You've Built the Business.
Now Set Yourself up for Life.

The wire hits, and suddenly you're managing more money than ever, fielding a dozen advisors with competing pitches, and facing tax decisions you can't reverse. For nine years I sat on the other side running a £200M+ single-family office for a founder. PostExitWealth is that experience, made available to you.

Why me

I'm not a founder telling you I've felt what you're feeling. I'm the person who ran the family office on the other side of it; nine years managing £200M+ for a founder throughout various liquidity events, across multiple jurisdictions. I've made these decisions from the inside, watched what works and what erodes wealth, and done it with no products to sell. Combined with 13 years working alongside founders and exiting my own fund, that's the vantage point PostExitWealth is built on.

Why Post-Exit Planning Matters

After the exit, the hard part starts

Whether your exit was £5M or £500M, the challenges are surprisingly similar and almost nobody prepares you for them.

Studies consistently find

70%
of significant wealth transfers don't survive the second generation
90%
are gone by the third generation
⅓
barely one in three founders feel more satisfied after the exit than before

These outcomes aren't inevitable. They're the result of predictable, avoidable mistakes: behavioral, structural, and the absence of a coherent framework for moving from earning wealth to stewarding it.

Sudden liquidity

You have more money than you've ever managed at once. Chapter 1 gives you a decision framework for the first 90 days: what to do, and critically, what not to do.

A tax bill that could buy a house

Chapter 2 maps tax strategy across US, UK, EU and Switzerland so you can keep what you earned, not just celebrate the gross number.

An identity without a title

Chapter 4 maps the emotional arc the first two years post-exit, identifies the identity trough, and helps you build what comes next with intention.

Wealth eroding without structure

Chapters 3–6 cover estate planning, concentration risk, diversification frameworks, and whether you need a family office before dispersed decisions erode what you built.

Who Is Behind PostExitWealth

Over 13 years working alongside founders and entrepreneurs, I've evaluated, invested in, and supported the growth of 70+ startups across sectors from early-stage ventures to exits and fund-level exposures. That founder-side perspective is one half of the picture; the nine years I spent setting up and operating a first-generation single-family office managing £200M+ is the other. Together they give me a rare vantage point into both the exit itself and everything that comes after.

Most wealth management advice is written for people with inherited or slowly accumulated wealth. You're different. You've just experienced a liquidity event, whether through a fund exit, a company sale, or a transaction windfall. Your situation has its own dynamics: concentration risk, identity transition, and the sudden complexity of diversification and family wealth structures.

My guidance is directional, not prescriptive. I don't give specific financial, legal, or tax advice, that's what your accountant, lawyer, and wealth advisor are for. But I can help you ask them the right questions, serve as your virtual family officer or help you set up your family office as independent advisor. I can help you think through the framework and find your way to the right advisors who can implement.
