Running a Family Office Under $100M

Learn how founders with under $100M can tactically build a digital-first family office. This step-by-step guide covers models (SFO, MFO, VFO), costs, jurisdictions, services, and best practices for protecting, growing, and passing your wealth.

If you're a tech founder sitting on $20M, $50M, or $100M+, you're already on one of the Advanced Levels of the Wealth Game.

The next big challenge?

Capital Concentration Risk and Coordination Failure.

Without a system to manage liquidity events, private investments, tax obligations, family governance, and cyber threats, your empire can crumble faster than you think.

A "family office" is that system.

Think of it as a command center for managing your capital, life, and legacy.

You don't need $500M to start. In fact, many digital-first founders effectively run family offices with less than $100M and are smashing it.

To do that effectively, you need a tactical setup. A family office brings order, resilience, and scalability to your financial life. It gives you control, privacy, and a professionalised system for managing wealth and capital preservation.

Let's break down how to run a family office that doesn't break the bank, maintain privacy, and add value beyond what your wealth advisor already does.

📌
Key Takeaways

You don't need $500M to start a family office — smart setups start at $20M-$200M.

Start lean: Virtual or Multi-Family Office models outperform Single-Family Offices below $200M.

Jurisdiction strategy is everything: tax, privacy, and succession protection must be engineered globally.

Prioritise investments, tax strategy, legal structuring, cybersecurity, and family governance early.

Keep total family office costs under 1% of assets — scalability and efficiency are non-negotiable.

Leverage technology aggressively: reporting, communication, document management, and security.

Think like an entrepreneur: modular, digital, and evolution-ready — not bloated or bureaucratic.

🧙🏻 The Family Office Archetypes

Before diving into models, understand where you fit among the family office archetypes:

Visionary Entrepreneur Family Office

Traditional Business Owner Family Office

Embedded Family Office

Professionalised Family Office

As Chew Mun Yew, head of private wealth at UOB, notes: "There are four critical enablers to partner with family offices: expertise with an advisory approach; efficient tech platforms; comprehensive bank propositions beyond just investments; and regional connectivity to serve the multi-jurisdictional nature of families."
