From operator to owner. Most founders try to protect wealth while still running everything. This is for those ready to step back — structuring capital intentionally so mistakes don't compound quietly. Asset protection, tax structures, geographic diversification, and concentration risk after exit.
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.
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.
Somewhere in your wealth manager's paperwork you're either retail or professional. One word decides what you're offered, what you pay, and what protection you keep. How the line works, what the institutional side opens up, and when it starts to make sense.
Roughly seven million people hold between $5m and $100m, and the wealth industry has never named them. Why the bracket exists, why it keeps growing, and how founders inside it run their money.
Founders copy other people's wealth setups and find they don't fit. A minimum viable family office is five jobs in the right order, and the first is a page of writing that half of them never produce.
The story going around is that AI finally lets a founder run their own money and skip the wealth manager. It has it backwards. AI is worst at the actual investment decisions, and best at making the people who make them cheaper to hire.
A full in-house family office runs $700k to $1m a year, which makes little sense below $100m. The cheaper route is to buy the same work from a multi-family office or an outsourced CIO, for a fraction of the cost.
Two family-office reports landed this month with the same quiet finding: the offices adopting AI are using it for paperwork, not portfolios.
Many founders hold investments personally when a holding structure would be more efficient. Options vary dramatically by jurisdiction and personal situation. Making the wrong choice creates unnecessary complexity; not choosing at all often costs money.
BADR jumped to 18%, carried interest to 47%, BPR/APR softened to £2.5m. Three weeks on, the most common excuse for deferring wealth-architecture work is gone. Peer-reviewed research on founder identity arrived alongside, pointing the same way.
Most founders hear "you need a family office" once they cross $10M in liquid assets. The real question isn't SFO vs MFO — it's which structure matches your actual complexity, not your aspirations. Here's the framework.
