A plain-language reference for founders managing serious wealth — built for the $5M–$100M+ range that traditional finance ignores and generic content underserves.
Most financial glossaries are written by compliance teams for compliance teams. This one is written for people who built companies, created liquidity, and now need to understand how wealth actually works — the structures, economics, and mechanics that nobody explains until you're already paying for expensive mistakes. Each term is defined with context specific to the founders. Where a concept connects to deeper analysis, we link to the relevant CapitalFounders.io Playbook.
This is educational content, not financial, tax, or legal advice. Your situation requires professionals who understand your specific circumstances.

Full Glossary
A
Accredited Investor
A regulatory classification defined by the SEC (in the US) that determines who can access private investment opportunities. The most common threshold is $1M in net worth excluding a primary residence, or $200K in annual income ($300K jointly) for the past two years. Most post-exit founders qualify automatically. The designation matters because it gates access to private equity funds, hedge funds, venture capital, and other alternative investments unavailable to the general public — though qualifying is only the first door. The more meaningful threshold is Qualified Purchaser status, which opens access to institutional-grade funds with better economics.
Allocation Drift
The gradual shift in a portfolio's asset mix as different holdings produce different returns over time. A founder who exits with a 60/40 split between equities and bonds might find themselves at 75/25 after a strong equity run — without having made a single decision. Drift is how concentration risk creeps back into a portfolio that was designed to avoid it. Left unchecked, it quietly rebuilds the exact vulnerability a founder diversified to escape.
Alpha
Returns generated above a benchmark, typically attributed to manager skill rather than broad market exposure. The wealth management industry talks about alpha constantly. Delivering it consistently is a different matter. For founders evaluating advisors and fund managers, the critical question isn't whether someone claims to generate alpha — nearly everyone does — but whether they can demonstrate it net of all fees, across a full market cycle, including periods when things went wrong. Most can't.
Alternative Investments
Any asset class outside traditional public equities, bonds, and cash — including private equity, venture capital, hedge funds, real estate, private credit, infrastructure, commodities, and collectables. Alternatives typically offer less liquidity, higher minimum investments, and longer holding periods. Founders are more comfortable with illiquidity than most investors (they held illiquid equity in their own businesses for years), but the fee structures and lock-up periods of institutional alternatives are a different kind of illiquidity — one where somebody else controls the timeline. (See: Private Equity for HNW Investors: Guide to Direct Deals & Club Investing)
Assets Under Management (AUM)
The total market value of assets a firm or advisor manages on behalf of clients. AUM is the dominant revenue driver in wealth management because most firms charge a percentage of it, typically 0.5%–1.5% annually. The incentive structure is worth understanding clearly: your advisor earns more when your portfolio grows, which sounds like alignment. It also means they're incentivised to gather and retain assets rather than recommend actions — like paying off debt or investing in your own business — that might reduce the pool they charge against.
B
Basis Points (bps)
A unit of measurement equal to one-hundredth of a percentage point. 100 basis points = 1%. Wealth management fees, fund performance, and interest rate movements are commonly expressed in basis points. When an advisor says their fee is "75 bps," they mean 0.75% annually. The number sounds small until you calculate it against a $20M portfolio compounding over a decade — at which point the cumulative cost becomes a six-figure annual drag that never appears on a single statement.
Blended Family Office
A hybrid arrangement where a founder uses a combination of external advisors, in-house staff, and technology platforms to replicate family office capabilities without building a full standalone operation. This is the practical middle ground for founders in the $10M–$50M range who need coordination and oversight but can't justify the $1M–$3M annual overhead of a dedicated single-family office. The challenge isn't building a blended model — it's preventing it from drifting into the fragmented mess it was designed to replace. (See: Running a Family Office Under $100M Playbook)
Blocker Corporation
A corporate entity (typically a C corporation) is inserted between a tax-exempt investor and a partnership investment to "block" Unrelated Business Taxable Income (UBTI) from flowing through. Founders holding alternative investments inside IRAs, foundations, or other tax-advantaged structures use blockers to avoid unexpected tax bills. The blocker pays corporate tax on the income instead, which is often lower than UBTI rates. Structuring decisions around blockers should happen before committing capital to a fund, not after receiving an unwelcome K-1.
Blueprint Wealth
A wealth management approach where the portfolio architecture is designed around a founder's specific life goals, risk tolerances, and time horizons — rather than starting with a model portfolio and retrofitting personal details around it. The opposite of "here's our balanced fund, it works for everyone." For founders whose wealth is concentrated, illiquid, or tied to specific liquidity timelines, starting from a standard allocation model misses the point entirely.
C
Capital Account
An investor's individual ledger within a partnership or fund, tracking their contributions, share of profits and losses, distributions received, and remaining balance. Your capital account tells you where you actually stand in a fund — not the headline return, but your specific position after fees, carry, and distributions. For founders investing in multiple partnerships, tracking capital accounts across vehicles is an operational task that gets messy fast without proper reporting infrastructure.
Capital Call
A demand from a private fund manager for investors to deliver a portion of their committed capital. When a founder commits $2M to a private equity fund, that money isn't transferred upfront — it's called in tranches over 3–5 years as the fund makes investments. Calls can arrive with as little as 10–14 days' notice, which means founders need to maintain sufficient liquid reserves to honour them. Missing a capital call can result in forfeiture of your existing investment and punitive dilution — consequences that are disproportionate to the operational failure of not having cash ready.
Carried Interest (Carry)
The share of profits a fund manager receives as performance-based compensation, typically 20% of gains above a defined hurdle rate. Carry is how private equity and venture capital managers build serious wealth — management fees cover costs, carry builds fortunes. For founders evaluating fund investments, the carry structure reveals incentive alignment: a manager earning 2% management fees on a $2B fund collects $40M annually regardless of performance. Their urgency to generate returns is different from a smaller manager whose personal economics depend on carry.
Carried Interest Recycling
A fund provision allowing the GP to reinvest realised gains (including their carry portion) back into the fund for additional investments rather than distributing them. Recycling can increase total investment capacity and improve net returns for LPs, but it also delays distributions and extends the fund's effective life. For founders, the recycling policy matters because it directly affects when cash comes back — a 10-year fund with aggressive recycling might not return meaningful capital until years 7–10.
Catch-Up Provision
A mechanism in fund economics that allocates a disproportionate share of profits to the GP after the hurdle rate is met, until the GP has received their full carried interest percentage on all cumulative profits. In practice, once LPs receive their preferred return (say 8%), the next tranche of profits goes entirely to the GP until the overall profit split reaches the agreed ratio (typically 80/20). The catch-up determines how quickly the GP starts earning on your returns — a 100% catch-up means the GP takes everything above the hurdle until they're "caught up," which can feel jarring to founders seeing their first fund distributions.
Clawback Provision
A contractual clause requiring a fund manager to return previously distributed carry if the fund's overall performance doesn't meet agreed thresholds by the end of its life. Without clawbacks, a manager could earn carry on early winners while the fund as a whole loses money — pocketing performance fees on deals that look good in isolation but mask a portfolio that's underwater. For founders investing in private funds, the presence and enforceability of clawback provisions are a basic alignment mechanism that should be non-negotiable.
Co-Investment
An opportunity for LPs to invest directly alongside a fund in a specific deal, usually with reduced or no management fees and carry. Co-investments let founders increase exposure to deals they find compelling without paying full fund economics. The catch: co-investments require fast decision-making (often 2–3 weeks), independent diligence capability, and comfort with concentrated positions. They also tend to be offered on larger deals where the GP needs additional capital, which creates selection bias worth understanding. (See: Private Equity Access for Founders Playbook)
Common Reporting Standard (CRS)
An international framework for the automatic exchange of financial account information between tax authorities across 100+ jurisdictions. CRS means that if a founder holds assets in Singapore, the Singapore tax authority automatically reports those holdings to the founder's home country. The practical implication is straightforward: offshore doesn't mean hidden. For globally mobile founders, CRS makes proactive tax compliance a structural requirement, not an optional exercise. Planning around CRS is about efficiency, not avoidance.
Concentration Risk
The danger of holding too much wealth in a single asset, sector, or geography. For founders, this usually manifests as a disproportionate net worth tied to a single company — either pre-exit equity or post-exit stock in the acquirer. Here's the reality: concentration creates wealth and then destroys it. Research consistently shows concentrated positions generate both the highest returns and the most catastrophic losses. The challenge isn't recognising the risk. It's acting while the concentrated position is still performing well, when every instinct says, "why would I sell a winner?"
Core-Satellite Portfolio
A portfolio construction approach combining a low-cost, broadly diversified core (typically index funds or ETFs representing 60–80% of assets) with higher-conviction satellite positions in alternatives, individual stocks, or thematic strategies. For founders who find pure passive investing intellectually unsatisfying but recognise that most active management destroys value, core-satellite provides a framework that scratches the itch for conviction without betting the whole portfolio on it. The discipline is keeping the satellites small enough that being wrong doesn't damage the core.
Custody
The safekeeping of financial assets by a qualified institution. Custody seems administrative until something goes wrong — and then it becomes the most important structural decision you made. Whoever holds your assets has operational control over them. For founders transitioning from a single brokerage account to a more complex structure with multiple managers and asset classes, understanding custody chains — who holds what, where, and under what protections — is a governance issue that deserves more attention than it typically receives. (See: Investment Landscape: Who Does What—and Why It Matters)
D
Direct Indexing
A portfolio strategy that replicates an index by owning individual stocks rather than a fund, enabling granular tax-loss harvesting at the individual security level. For founders with large taxable portfolios — particularly in the first few years after an exit when newly established positions haven't all appreciated — direct indexing can generate meaningful tax alpha, often 1–2% annually. It typically requires a $500K+ minimum and a platform or advisor that supports it. The concept is simple. The execution is operationally intensive, which is why it became accessible only recently as technology reduced costs.
Diversification
Spreading investments across different asset classes, geographies, sectors, and time horizons to reduce the impact of any single loss. Every founder knows diversification is sensible. Few find it emotionally easy. The transition from concentrated wealth (the bet that made you rich) to diversified wealth (the structure that keeps you rich) requires a genuine identity shift — from builder to steward. The founders who diversify earliest tend to do it best, because they act from a position of strength rather than reacting after a drawdown forces their hand.
Domicile vs Tax Residence
Two concepts that sound interchangeable but carry different legal weight. Domicile is your permanent home — the jurisdiction you intend to return to and where your deepest ties exist. Tax residence is determined by where you spend time, earn income, or meet specific statutory tests in a given year. You can be tax resident in one country while domiciled in another, and the interaction between these two statuses determines which country taxes what income, how, and when. For globally mobile founders, getting this wrong creates double taxation or compliance failures that compound over the years before anyone notices.
Donor-Advised Fund (DAF)
A charitable giving vehicle that allows founders to make a tax-deductible contribution now and distribute grants to charities over time. DAFs are particularly powerful in high-income years — including the year of a business exit — because they front-load the tax deduction while giving the founder years to decide which organisations receive grants. The contribution is irrevocable (the money belongs to charity), but the founder retains advisory privileges on timing and recipients. For founders who know they want to give but aren't ready to choose where, DAFs remove the pressure of rushed philanthropic decisions during an already overwhelming transition.
DPI (Distributed to Paid-In Capital)
A private fund performance metric measuring actual cash returned to investors divided by total capital contributed. A DPI of 1.0x means you've gotten your money back. Above 1.0x, you're in profit. DPI is the metric that separates real returns from paper marks — unlike TVPI, which includes unrealised NAV, DPI only counts money that has actually landed in your account. Founders should ask managers about DPI early and often, especially for funds past their fifth year. A fund showing a 2.0x TVPI with a 0.3x DPI is telling you a story that hasn't been proven with cash yet.
Drawdown (Investment)
The decline from a portfolio's peak value to its lowest point before recovery. A 30% drawdown on a $20M portfolio means the value dropped to $14M. For founders, drawdowns are psychologically specific: the instincts that built wealth — conviction, doubling down, staying aggressive — are the opposite of what drawdowns require. Watching a portfolio decline while doing nothing triggers every operator instinct to act, which is precisely when action is most likely to be destructive.
Dry Powder
Uncommitted capital available for future deployment. In private equity, dry powder refers to capital raised but not yet deployed. For individual founders, maintaining dry powder means keeping enough liquid reserves to meet capital calls, seize opportunities, or survive downturns without forced selling. The tension is real: too much dry powder means cash drag on long-term returns. Too little means vulnerability at the worst moment. Most founders under-allocate to dry powder because holding cash feels unproductive — until the quarter when it becomes the most productive asset they own.
E
Earn-Out
A component of an acquisition where a portion of the purchase price depends on the business hitting specific performance targets post-sale. Earn-outs extend the founder's financial exposure to a business they no longer control — and therein lies the problem. Acquirers change strategy, replace teams, and restructure operations in ways that affect earn-out metrics but aren't within the founder's power to prevent. For founders negotiating exits, the earn-out amount matters less than the probability-adjusted value: what's it actually worth given the conditions, the acquirer's track record, and your realistic ability to influence outcomes?
Emerging Wealthy Founder™
A term coined by CapitalFounders.io to describe founders holding $5M–$100M in investable assets, typically from a business exit or a meaningful liquidity event. This cohort sits in a gap the financial industry largely ignores: too wealthy for retail advisory platforms, too small for institutional family office services, and too sophisticated to accept generic advice packaged as wisdom. Emerging Wealthy Founders share recognisable traits — global mobility, scepticism of traditional finance, high agency, and an identity built around creation rather than management. The wealth management industry is structured to serve people above and below this range. Serving this group requires a fundamentally different approach.
Endowment Model
An investment approach pioneered by large university endowments (Yale being the most cited example) that emphasises heavy allocation to alternatives — private equity, venture capital, real assets, hedge funds — alongside traditional stocks and bonds. The model has delivered strong long-term returns for institutions with permanent capital and infinite time horizons. Individual founders cannot replicate it directly. You don't have a 300-year investment horizon, you can't absorb five years of illiquidity without lifestyle impact, and you don't have a development office raising new capital annually. Taking inspiration from the endowment model is reasonable. Copying it literally is a mistake.
Estate Planning
The process of arranging how assets will be transferred, managed, and taxed at death or incapacity. For founders, estate planning involves business interests, multi-jurisdictional assets, trusts, insurance structures, and family governance that standard templates don't cover. The most expensive estate planning mistake is not paying too much tax — it's doing nothing and letting default rules apply. Default rules are designed for average estates. Founder estates are not average.
F
Family Office
A private organisation managing the financial and administrative affairs of a wealthy family. Single-family offices (SFOs) serve one family; multi-family offices (MFOs) serve several. The term is used so loosely in the industry that it's almost meaningless — a founder with a part-time bookkeeper and a founder running a 50-person, $5B operation both call themselves "family offices." For founders under $100M, the question isn't whether to build one. It's which specific capabilities they actually need and what's the most cost-effective way to source them. (See: Running a Family Office Under $100M Playbook)
FATCA (Foreign Account Tax Compliance Act)
A US law requiring foreign financial institutions to report to the IRS accounts held by US persons. FATCA makes it functionally impossible for US-connected founders to hold unreported foreign accounts, and it makes many foreign institutions reluctant to accept US clients at all. For founders with US citizenship or residency, FATCA obligations follow them globally and affect which banks will work with them, which jurisdictions are practical, and the compliance overhead of every international structure.
Fee-Only vs Fee-Based
Two advisor compensation models that sound similar but operate differently. Fee-only advisors earn compensation solely from client fees — no commissions, no product sales, no revenue sharing with fund managers. Fee-based advisors charge fees but may also earn commissions on products they recommend. The distinction matters because commission-based incentives can steer advice toward products that pay the advisor rather than serve the client. Fee-only doesn't guarantee good advice. But it removes one structural conflict that fee-based models leave intact.
Fiduciary Duty
A legal obligation to act in a client's best interest. In the US, Registered Investment Advisors (RIAs) owe a fiduciary duty to clients; broker-dealers operate under a lower "suitability" standard, meaning they only need to recommend products that are "suitable" — not necessarily optimal. For founders choosing advisors, the fiduciary question is baseline, not sufficient. An advisor without a legal obligation to prioritise your interests probably won't when your interests conflict with their revenue.
Fragmentation Tax™
A concept coined by CapitalFounders.io describing the hidden cost founders pay when their wealth is spread across disconnected advisors, accounts, structures, and jurisdictions with no unified oversight. The fragmentation tax doesn't appear on any statement. It shows up as missed tax optimisation, duplicated fees, uncoordinated risk exposure, contradictory advice, and decisions made without full visibility into the overall picture. For founders in the $5M–$50M range who've accumulated three advisors, two accountants, four brokerage accounts, and a trust they set up years ago, fragmentation is often the single largest drag on wealth that nobody is measuring — because nobody has the complete picture. (See: The Fragmentation Tax Playbook)
Fund of Funds (FoF)
An investment vehicle that allocates capital across multiple underlying funds rather than investing directly in companies or assets. FoFs offer diversification, access to top-tier managers who may be otherwise closed to new investors, and professional fund selection. The cost: an extra layer of fees, typically 0.5–1% management plus 5–10% carry, stacked on top of the underlying funds' own economics. For founders early in their alternatives journey, FoFs can be a reasonable access vehicle. As portfolio size grows and direct fund relationships develop, the compounding fee drag makes them harder to justify.
G
Geographic Diversification
Distributing assets, structures, and sometimes residency across multiple jurisdictions to reduce exposure to any single country's political, regulatory, or economic risk. For globally mobile founders, geographic diversification isn't paranoia — it's insurance that most people buy too late. A single government's policy change, currency crisis, asset freeze, or regulatory shift shouldn't be able to damage your entire financial life. The execution requires navigating CRS reporting, substance requirements, and cross-border tax treaties, which is where most founders underestimate the complexity. (See: Family Office Location Guide)
Governance (Investment)
The system of rules, practices, and decision rights determines how investment decisions are made, executed, and monitored. For founders managing meaningful capital, governance answers specific questions: Who has the authority to make investment decisions? What size of commitment requires approval? How are managers evaluated and replaced? How are conflicts of interest identified and managed? Founders who built companies understand operational governance instinctively. Applying the same discipline to their personal capital is where most fall short — not because they can't, but because nobody told them it was necessary. (See: Investment Governance Playbook)
GP (General Partner)
The managing entity of a private fund — the people who make investment decisions, run operations, and earn management fees and carried interest. In any private equity or venture capital fund, the GP does the work while the LPs provide capital. For founders evaluating fund investments, the GP is the investment. Their track record, team stability, incentive alignment, decision-making process, and operational capability matter more than the fund's marketing deck or sector thesis.
GP Commit
The amount of personal capital a fund's general partner invests alongside its LPs, typically expressed as a percentage of the fund's total size. Industry norms range from 1–5%, though committed GPs invest more. GP commitment matters because it reveals skin in the game — a manager investing 5% of a $500M fund ($25M of their own money) makes different decisions than one investing the minimum. For founders, GP commitment is one of the simplest and most reliable signals of alignment. If the manager wouldn't invest meaningfully in their own fund, that tells you something.
GRAT (Grantor Retained Annuity Trust)
An estate planning structure allowing a founder to transfer appreciating assets to beneficiaries while minimising gift and estate taxes. The founder places assets in a trust, receives fixed annuity payments for a defined term, and any appreciation above the IRS-set rate (the Section 7520 rate) passes to beneficiaries tax-free. GRATs work best when interest rates are low and expected asset appreciation is high — making them particularly relevant for founders holding pre-IPO stock or concentrated positions with significant anticipated upside. Timing and structure matter enormously; a poorly designed GRAT provides no benefit.
H
High-Water Mark
A provision ensuring a fund manager only earns performance fees (carry) on new profits, not on recovering previous losses. If a fund drops from $100M to $80M, the manager must recover to $100M before earning carry on further gains. Without a high-water mark, you'd pay performance fees twice: once on the way up, again on the recovery. Any fund that doesn't include this provision is asking you to subsidise their bad years. It should be a non-negotiable term.
Holding Company
A legal entity whose primary purpose is owning assets — shares in operating companies, investments, real estate, and intellectual property — rather than conducting operations directly. Founders use holding companies to separate personal liability from business assets, consolidate ownership for tax efficiency, and create cleaner estate-planning and wealth-transfer structures. Jurisdiction matters significantly: a Delaware LLC, a UK limited company, and a Singapore holding company each carry different tax, reporting, and liability characteristics. The structure should follow the strategy, not the other way around.
Hurdle Rate
The minimum return a fund must generate before the GP earns performance fees (carried interest). The most common hurdle is 8% — meaning the manager only earns carry-on returns above that threshold. For founders, the hurdle rate is a negotiation signal. A GP confident in their ability to deliver strong returns will accept a meaningful hurdle. No hurdle or a low hurdle means the manager starts earning carry before you've received a reasonable return on your capital. Combined with the catch-up provision, these two terms define the economics of your relationship with every private fund manager.
I
Illiquid Assets
Investments that cannot be quickly converted to cash without significant value loss or extended time horizons. Private equity, venture capital, real estate, and business equity all qualify. The irony for founders is obvious: the asset that created their wealth was deeply illiquid — they held company equity for years. Post-exit, some over-correct toward liquidity and leave returns on the table. Others immediately lock capital into new illiquid vehicles without appreciating that this time, they chose the illiquidity rather than having it imposed by building a business. That distinction matters when markets turn and the lock-up feels different from the inside.
Internal Rate of Return (IRR)
The annualised return that accounts for the timing and size of all cash flows into and out of an investment. Unlike a simple return percentage, IRR captures when capital was deployed and returned, which matters enormously in private markets where money is called gradually and distributed unevenly over years. A fund reporting 25% IRR sounds impressive until you learn it used a subscription credit line to delay capital calls (artificially inflating early returns), took 8 years to return capital, and the bulk of gains arrived in the final year. IRR can be engineered. Sophisticated investors look at it alongside MOIC, DPI, and TVPI to separate real performance from financial presentation.
Investment Policy Statement (IPS)
A written document defining a founder's investment objectives, risk tolerance, time horizon, liquidity needs, constraints, and governance framework. An IPS is the operating agreement between you and your advisors — or between present-you and future-you during a market panic. It answers questions in advance: what's the asset allocation? When do we rebalance? What triggers a strategy review? Most founders don't have one. The founders who do make fewer reactive decisions, because the framework for saying "no" already exists. (See: Investment Governance Playbook)
J
J-Curve
The pattern of negative returns in the early years of a private equity fund, caused by management fees, initial investment costs, and the time required for portfolio companies to create value. Fund returns dip below zero (the bottom of the "J") before curving upward as exits and distributions begin, typically in years 4–7. For founders making their first private fund commitment, the J-curve is disorienting. Watching an investment lose reported value for 2–4 years while management fees compound requires a kind of patience that public market investing never demands. Understanding the J-curve before committing capital is the difference between holding through it and panicking out of it.
K
Key Person Clause
A provision in fund agreements that triggers specific consequences — usually suspension of new investments and sometimes the right to withdraw capital — if a named individual (typically the lead GP or CIO) leaves, dies, or becomes incapacitated. Private fund performance is often concentrated in a small number of decision-makers. Investing in a fund without key person protections means you evaluated one team and might end up invested with a different one. For founders, this is familiar logic: you wouldn't invest in a startup without understanding what happens if the founder leaves.
L
Liquidity Event
Any transaction that converts an illiquid asset into cash or near-cash. For founders, the most common liquidity events are business sales, IPOs, secondary share sales, and PE recapitalisations. The financial mechanics are straightforward. The psychological impact is not. The transition from "wealthy on paper" to "wealthy in cash" changes identity, daily structure, motivation, and decision-making in ways that the vast majority of founders don't anticipate until they're living through it. Post-exit capital destruction — making expensive mistakes in the 12–36 months after liquidity — is the single most common wealth failure pattern among founders.
Liquidity Planning
Ensuring a founder maintains sufficient, readily accessible cash and near-cash assets to meet obligations, seize opportunities, and address emergencies without forced selling of long-term holdings. Good liquidity planning answers one question: "If everything goes wrong simultaneously — markets crash, a capital call arrives, a business needs emergency capital, and I need cash for a personal crisis — am I okay?" Most founders plan for average conditions. Liquidity planning is about surviving the scenario you think is unlikely.
LP (Limited Partner)
An investor in a private fund who provides capital but has no role in investment decisions or management. LPs have limited liability — they can lose their investment but aren't responsible for fund debts or obligations. When a founder invests in a private equity or venture capital fund, they become an LP. The relationship is governed by the Limited Partnership Agreement (LPA), which defines fees, reporting, distributions, governance rights, and the circumstances under which you can (and more importantly, cannot) exit.
M
Management Fee
The annual fee a fund manager charges to cover operational costs — salaries, office, travel, legal, and administration. Typically 1.5–2% of committed capital during the investment period and 1–1.5% of invested capital during the harvest period. Management fees are charged regardless of performance. On a $2M fund commitment, a 2% fee extracts $40K annually, whether the fund returns 30% or loses money. Over a 10-year fund life, cumulative management fees alone can consume 15–20% of committed capital before a single investment return is generated.
Mode Progression
A behavioural framework used at CapitalFounders.io that describes the internal transitions founders go through as their relationship with wealth evolves. The progression runs Growth Mode (building, scaling, creating capital) → Operator Mode (running systems, optimising for stability) → Owner Mode (designing structures, governance, and incentive architecture) → Allocator Mode (deploying capital across assets with institutional discipline). Most wealth destruction occurs when founders remain stuck in Growth Mode — still chasing deals and momentum — after their situation demands Owner or Allocator thinking. The modes aren't stages you graduate from permanently. Founders building a second company may cycle back through earlier modes while maintaining Allocator discipline for their existing capital.
MOIC (Multiple on Invested Capital)
Total value returned by an investment divided by total capital invested, expressed as a multiple. A 3.0x MOIC means $1 invested returned $3. MOIC ignores timing — 3.0x over 3 years is exceptional; 3.0x over 12 years is mediocre. But it provides something IRR doesn't: a simple, unmanipulable measure of how much money you actually made. Founders should evaluate private investments using both MOIC and IRR. A fund showing high IRR with low MOIC likely used financial engineering (subscription credit lines, early distributions) to flatter the time-weighted return.
Multi-Family Office (MFO)
A firm providing family office services — investment management, tax coordination, estate administration, reporting, and sometimes lifestyle and concierge — to multiple families simultaneously. MFOs give founders access to institutional-grade capabilities without the overhead of building a dedicated single-family office, typically serving clients with $10M–$100M+ in assets. The tradeoff: less customisation than an SFO, shared attention across multiple clients, and potential conflicts of interest if the MFO earns revenue from product placement alongside advisory fees. Asking how the MFO generates revenue beyond advisory fees is always worthwhile. (See: Running a Family Office Under $100M Playbook)
N
Net Asset Value (NAV)
The total value of a fund's or entity's assets minus liabilities. In private funds, NAV is reported periodically (usually quarterly) based on the manager's internal valuations, which may or may not reflect what those assets would sell for today. The gap between reported NAV and realisable value is particularly important in private holdings. A fund's NAV might show steady growth, but until distributions arrive, that value is the manager's opinion. DPI tells you what's real.
O
Opportunity Zone
A US tax incentive providing capital gains tax benefits for investments in designated economically distressed areas. Founders who invest recently realised capital gains into Qualified Opportunity Zone Funds can defer and partially reduce the original gain, and eliminate capital gains on new appreciation if held for 10+ years. Opportunity Zones are most relevant for founders with large, recent capital gains — particularly post-exit. The tax benefit is real, but the underlying investment (usually real estate or a business in the designated zone) carries its own risk profile, independent of the tax advantage.
P
Pledge Fund
A private fund structure where LPs commit to evaluate deals individually rather than committing capital upfront. Each time the GP identifies an investment, LPs decide whether to participate. Pledge funds offer founders more control and flexibility per deal, but they create a fundamental tension: the GP can't guarantee capital, which means the best deals (which require speed and certainty) may go elsewhere. For founders who want deal-by-deal control, pledge funds are attractive. For access to top-performing managers, they're often a compromise.
Post-Exit Capital Destruction
The pattern of significant wealth loss in the 12–36 months following a business sale, driven by a specific and predictable combination of overconfidence, identity disruption, unfamiliar asset classes, and the sudden absence of the operational structure that previously governed every decision. Founder interviews and research consistently show that the highest-risk period for capital isn't during the building phase — it's immediately after the exit, when founders have maximum capital and minimum experience managing it. The pattern is so consistent it's practically a lifecycle stage. (See: Post-Exit Path Playbooks)
Private Credit (Private Debt)
Loans and debt instruments are provided by non-bank lenders, typically structured as private funds. Private credit includes direct lending, mezzanine financing, distressed debt, and speciality lending. For founders, private credit can provide predictable income streams — often 8–14% annually — with lower correlation to public equity markets. The risk profile differs from equity: you're the lender, not the owner. Default risk, illiquidity, and valuation opacity are the primary concerns. In a rising-rate environment, floating-rate private credit can be particularly attractive, but credit quality matters more than yield.
Private Equity (PE)
Investment in private companies through buyouts, growth equity, or recapitalisations, typically structured as limited partnership funds with 7–12 year lifecycles. PE firms acquire companies, improve operations or capital structure, and sell at a higher valuation. For founders, private equity sits on both sides of the table: as a potential acquirer of their business, and as an asset class for post-exit allocation. The performance dispersion in PE is extreme — the difference between top-quartile and bottom-quartile funds dwarfs the equivalent spread in public markets. Access to top-performing managers requires relationships, minimum commitments, and a track record that takes time to build. Starting early matters. (See: Private Equity Access for Founders Playbook)
Private Placement Life Insurance (PPLI)
A specialised insurance wrapper that provides tax-advantaged growth for a portfolio of investments held within a life insurance policy. PPLI can hold alternatives, hedge funds, and other assets that would normally generate taxable income or gains. For founders in high-tax jurisdictions with long time horizons (typically 15+ years), PPLI can meaningfully reduce lifetime tax drag. The structures are complex, insurance costs are real, compliance requirements are jurisdiction-specific, and assets must be managed by an independent investment manager—not the policy owner. This is a tool for deliberate, long-term planning, not a quick tax hack.
Q
QSBS (Qualified Small Business Stock)
A US tax provision (Section 1202) allowing founders and early employees to exclude up to $10M — or 10x their cost basis, whichever is greater — in capital gains from federal taxation when selling shares in a qualifying C corporation held for at least five years. QSBS is one of the most significant tax benefits available to US founders. The qualification requirements are specific: the company must be a C corporation, have gross assets under $50M at the time of stock issuance, and operate in an eligible industry. These requirements must be met at the time shares are issued; retroactive qualification is not possible. If your company might qualify, structuring for QSBS eligibility should happen years before any exit conversation begins.
Qualified Purchaser
A regulatory threshold above accredited investor, requiring $5M+ in investments (not net worth). Qualified purchaser status unlocks access to "3(c)(7) funds" — institutional-grade private funds with fewer regulatory restrictions, larger investor bases, and often better fee terms. For founders in the $5M–$50M range, reaching qualified purchaser status opens doors to managers and strategies that accredited investor status alone can't access. It's the point where the private markets menu expands meaningfully.
R
Rebalancing
Adjusting a portfolio back to its target allocation by selling assets that have outgrown their target weight and buying those that have fallen below. The concept is simple. The execution is psychologically brutal — it requires selling winners and buying losers, which contradicts every instinct that made a founder successful through concentrated conviction. Systematic rebalancing on a predetermined schedule (quarterly, semi-annually) consistently outperforms discretionary rebalancing driven by market views or emotions. The IPS should define the rebalancing rules. The founder should follow them.
Registered Investment Advisor (RIA)
A firm or individual registered with the SEC or state regulators to provide investment advice for compensation. RIAs owe a fiduciary duty to clients, legally requiring them to act in the client's best interest. This distinguishes RIAs from broker-dealers and wirehouses operating under suitability standards. For founders selecting advisors, RIA registration is a minimum qualification — not a guarantee of quality, competence, or alignment, but a structural floor that ensures the person giving you advice is legally required to prioritise your interests.
Regulation D (Reg D)
The SEC regulation governing private placements is the legal mechanism through which private funds and companies raise capital without public registration. Reg D creates the framework for Rule 506(b) and 506(c) offerings, which are how founders access most private equity, venture capital, and hedge fund investments. Understanding Reg D matters because it defines who can invest (accredited investors and qualified purchasers), what disclosures are required, and what restrictions apply to reselling the securities. Every private fund subscription document references Reg D. Knowing the basics prevents surprises.
S
Section 409A Valuation
An independent appraisal of a private company's common stock fair market value, required for setting the exercise price of stock options and other deferred compensation. For founders issuing equity to employees pre-exit, a 409A valuation that's too low creates IRS problems; one that's too high makes equity grants less attractive to employees. The valuation must be conducted by a qualified independent appraiser and is typically refreshed annually or after material events (fundraising rounds, significant revenue changes). Getting this wrong doesn't just create tax liability — it can affect the company's entire equity compensation structure.
Securities-Based Lending (SBL)
Borrowing against a portfolio of securities rather than selling them — accessing liquidity without triggering capital gains taxes, typically at interest rates lower than unsecured alternatives. SBL is elegant in stable markets and dangerous in volatile ones. If the collateral's value drops significantly, the lender issues a margin call requiring additional collateral or forced selling at the worst possible time. For founders considering SBL for major purchases or bridge financing, the critical exercise is stress-testing: what happens to this loan if my portfolio drops 30% in a month? If the answer involves forced selling, the structure needs rethinking.
Separately Managed Account (SMA)
A portfolio of individually owned securities managed by a professional investment manager on behalf of a single client. Unlike mutual funds or ETFs, you own each underlying security directly, which enables customised tax management, ethical screening, concentrated stock exclusions, and full transparency. SMAs are common for founders with $1M+ in a single strategy. They're the structural building block behind direct indexing and tax-optimised portfolio management.
Side Letter
A separate agreement between an LP and a GP that modifies the standard fund terms for that specific investor. Side letters can grant fee discounts, preferential co-investment rights, enhanced reporting, specific liquidity provisions, or other bespoke terms. They're standard practice in institutional investing and increasingly accessible to founders committing meaningful capital ($1M+). For founders, asking about side letter availability signals sophistication and often unlocks terms that aren't offered unless requested. The worst that happens is the GP says no.
Single Family Office (SFO)
A dedicated organisation serving one family's complete financial, administrative, and lifestyle needs. SFOs typically require $100M+ in assets to justify the overhead — staff, office, technology, compliance, legal, and governance infrastructure can easily run $1M–$3M annually before investment management fees. For founders below that threshold, building an SFO prematurely is one of the most common and most expensive post-exit mistakes. It creates institutional complexity and cost without proportional benefit, often driven by the false belief that "having my own family office" is the natural next step after a successful exit. (See: Running a Family Office Under $100M Playbook)
SPV (Special Purpose Vehicle)
A legal entity created for a specific, narrow purpose — holding a single investment, isolating risk, or structuring a particular transaction. Founders encounter SPVs when co-investing alongside funds, participating in syndicated deals, or structuring their own investments. SPVs provide liability isolation and clean accounting, but they also add administrative costs and legal complexity. Each SPV is another entity to maintain, file for, and eventually wind down.
Subscription Credit Line
A fund-level lending facility that allows a GP to borrow money (using LP commitments as collateral) to make investments before calling capital from LPs. Subscription lines smooth capital calls and provide operational flexibility for the GP. The effect on performance reporting: by delaying the point at which LP capital is "in the ground," subscription lines mechanically inflate IRR — sometimes significantly. A fund reporting 25% IRR might show 18% without the credit line. This isn't fraud; it's financial engineering. For founders evaluating funds, asking for returns both with and without the subscription line gives a clearer picture of actual investment performance.
Substance Requirements
Tax and regulatory rules require that an entity have genuine economic activity — employees, decision-making, physical presence — in the jurisdiction where it's established. Substance requirements exist to prevent paper-only structures: a holding company "based" in a low-tax jurisdiction that actually operates entirely from London or New York. For founders using international structures, ensuring adequate substance is essential for those structures to be respected by tax authorities. Getting substance wrong doesn't just create a tax problem — it can cause the entire structure to be disregarded, with retrospective consequences. (See: Family Office Location Guide)
T
Tax-Loss Harvesting
Selling investments at a loss to offset capital gains taxes, then reinvesting in similar (but not "substantially identical") assets to maintain market exposure. Systematic tax-loss harvesting can generate 1–2% in annual tax alpha for taxable portfolios. For founders in the first few years after an exit, when many newly established positions haven't all appreciated, the harvesting opportunity window is richest. The wash sale rule (preventing repurchase of "substantially identical" securities within 30 days) requires careful execution, which is why this strategy works best through direct indexing platforms or tax-aware SMAs rather than manual trading.
TVPI (Total Value to Paid-In Capital)
Total value — both distributed cash and remaining NAV — divided by total capital contributed. A TVPI of 1.5x means the fund has returned or is currently valued at 1.5 times what investors put in. TVPI includes unrealised value, so it depends on the GP's valuation of assets they haven't sold yet. That's why TVPI should always be read alongside DPI. A fund showing 2.5x TVPI with 0.4x DPI is mostly telling you about their accounting, not your returns.
U
Unrelated Business Taxable Income (UBTI)
Income generated by tax-exempt entities (IRAs, foundations, endowments) from activities unrelated to their tax-exempt purpose which becomes subject to regular income tax. For founders holding alternative investments in IRAs or other tax-advantaged structures, UBTI can create unexpected tax liability — particularly from leveraged real estate or certain partnership investments that generate debt-financed income. The solution is structural: blocker corporations or specific fund structures can mitigate UBTI exposure, but the planning must happen before capital is committed, not after the K-1 arrives.
V
Vintage Year
The year in which a private fund makes its first investment or closes on committed capital. Vintage year matters because private fund performance is heavily influenced by economic conditions at entry — funds deploying capital at market bottoms tend to outperform those buying at peaks. For founders building a long-term private markets allocation, committing capital across multiple vintage years (sometimes called "vintage year diversification") reduces the risk of concentrating all their illiquid exposure at a single point in the cycle. It's the private markets equivalent of dollar-cost averaging.
Virtual Family Office (VFO)
A model where a founder assembles a coordinated network of independent specialists — investment advisor, tax accountant, estate attorney, insurance consultant — who collaborate under a unified strategy without a dedicated in-house team. VFOs rely on technology for aggregated reporting and a quarterback (often the lead advisor or the founder themselves) for coordination. For founders in the $5M–$30M range, this is often the most cost-effective way to achieve family-office-level coordination without the overhead. The risk is that "virtual" becomes a polite way of saying "fragmented" if no one actually owns the coordination role. (See: Running a Family Office Under $100M Playbook)
W
Waterfall (Distribution)
The sequence in which a fund distributes profits between LPs and the GP. The two dominant structures are the European waterfall (whole-fund: carry is calculated on overall fund performance, meaning the GP earns carry only after all invested capital plus preferred return is returned across the entire fund) and the American waterfall (deal-by-deal: carry is calculated on individual investments, allowing the GP to earn carry on successful deals even if the fund overall hasn't returned all capital). European waterfalls are more LP-friendly. American waterfalls are more GP-friendly. For founders, understanding which waterfall structure a fund uses — and how it interacts with the clawback provision — directly affects when you receive distributions and how much the GP earns relative to your returns.
Wealth Architecture
A framework used at CapitalFounders.io describing the deliberate design of how wealth is structured, held, protected, and deployed. Wealth architecture encompasses entity structures, jurisdictional decisions, custody arrangements, governance frameworks, tax strategy, and portfolio construction as an integrated system. Most founders focus primarily on what to invest in — which stock, which fund, which allocation. Wealth architecture focuses on how the entire system is designed: which entities hold which assets, in which jurisdictions, under what rules, and overseen by whom. Getting the architecture right matters more than getting any single investment right, because structural decisions compound across the entire portfolio. (See: Wealth Architect Playbooks)
Wealth Management
The professional service of managing a client's financial life across investment management, financial planning, tax strategy, estate planning, and risk management. The term is broad enough to be almost meaningless — from a solo financial planner to a global bank, everyone describes their service as "wealth management." For founders, the distinction that matters is between transactional wealth management (selling products and charging for transactions) and advisory wealth management (coordinating strategy across the full financial picture and charging for that coordination). The labels on the door are often identical. The service behind them is not.
Wealth Preservation vs Wealth Growth
Two fundamentally different investment philosophies that founders must navigate — often simultaneously. Wealth growth prioritises maximising returns, accepting higher volatility and concentration in pursuit of compounding. Wealth preservation prioritises protecting existing capital against permanent loss, favouring diversification, liquidity, and downside protection over return maximisation. The shift from growth to preservation is one of the most difficult psychological transitions for founders, because the mindset that created their wealth (concentrated conviction, risk tolerance, aggressive action) is the opposite of what it takes to preserve it. Most founders don't switch completely from one to the other — they find a personal ratio that reflects their risk capacity, time horizon, and identity.
Numerical / Symbols
10b5-1 Plan
A pre-arranged trading plan allows corporate insiders to sell shares on a predetermined schedule, providing legal protection against insider trading allegations. For founders holding public company stock post-IPO or acquisition, a 10b5-1 plan creates a systematic mechanism to diversify concentrated positions without creating legal exposure or sending negative market signals. Plans must be established during a period when the insider doesn't possess material non-public information, and recent SEC rule changes have added mandatory cooling-off periods and disclosure requirements.
1031 Exchange
A US tax provision deferring capital gains when selling one investment property and reinvesting proceeds into a "like-kind" property within strict timelines — 45 days to identify potential replacement properties, 180 days to close. For founders with real estate holdings, 1031 exchanges can defer substantial tax liabilities across multiple transactions, potentially indefinitely. The constraint: the capital remains locked in real estate. A founder using a 1031 exchange to defer a $3M gain is preserving tax efficiency but also choosing to keep that capital in property rather than diversifying into other asset classes. The tax tail shouldn't wag the investment dog.
83(b) Election
A US tax election that allows a founder or employee to pay ordinary income tax on the fair market value of restricted stock at the time of grant rather than at vesting. If the stock appreciates substantially between grant and vesting, the 83(b) converts what would have been ordinary income into long-term capital gains — a significant rate difference. The filing deadline is absolute: 30 days from the date of the stock grant. No extensions. No exceptions. No retroactive filings. Missing this deadline is one of the most expensive administrative errors a founder can make, often costing six or seven figures in unnecessary taxes.
