How founders with $5M–$100M run their own capital like a business: structure, investing, top professionals on call, and systems that do the rest.
Specialist investors have deployed billions to buy service businesses, then transform them with AI. This playbook explains the model, the players, and what it means for founders who might sell, invest, or build.
A complete wealth operating system for founders with $5M–$100M in liquid assets.
Can AI do the due diligence on a fund or a deal for you? In a 2026 test, the best model got 57% of questions on SEC filings right, even with the right passages in front of it. You'll also see what one evergreen fund's small print says about fees and getting your money out, and get a prompt to try.
Hedge funds can help your portfolio lose less in a bad year, and they often make less in good ones. On $1m over five years, a feeder could leave you a little over half the gain after both layers of fees. Five questions to ask before you invest in one.
Founders with $5M–$100M get offered plenty of products and little help running the whole thing. Capital Founders OS is a model for that: four pillars, you in the middle, top professionals on call and systems doing the heavy lifting.
Once they've sold, many founders put their money back into what they already know, often without noticing. Why that happens, and how to check your own holdings.
Most of your wealth sits in one company, and the sale is the move you spend years picturing. Why it's OK to take some money off the table as the business grows, what that does for your risk and your stress, and what two founders got from billion-dollar valuations.
Ask about a family office at $30m and you get four names back and almost no prices. What each one costs, who ends up making the decisions, and what you are really buying when someone offers you a fractional setup.
Anthropic put a price on the packaged adviser stack last week, and the people who sell that software for a living were the least excited in the room. Look at what shipped and you can see who it was built for. If you run your own money, the tool is the cheap part and the checking is still yours.
Sooner or later someone suggests hiring one person to coordinate the accountant, the lawyer and the portfolio manager. Whether that's a hire or still you is a question of stage, not how much you have. What it costs, and the page worth writing before you look for anybody.
Most founders carry a number in their head, and many set it against the company's valuation. Carta's ownership ladder shows how little of that number is theirs by Series C, and why the version that survives the exit is the one written down early, on your own balance sheet.
Founders arrive at liquidity expecting to keep the pace of the business, and that pace is where money gets lost. Mindset first, then people, then four buckets that give every part of the money a job before any deal gets a yes. The order matters more than the picks.
One person can run a successful business, and founders stopped arguing about that a while ago. This piece takes the same idea to money: what a solo family office is, where it sits beside single and multi, and what running one looks like at $5M–$100M.
Most founders with $5M–$100M already run their money themselves, with professionals on call and no staff on payroll. That arrangement has never had a name. This week it gets one, and a standard to run to.
