The Wire Has Landed.
Now Set Yourself up for Life.

Suddenly you are managing more money than ever, fielding a dozen advisors with competing pitches, and facing decisions you can't reverse. The Setup is a short, fixed-fee engagement that takes you from "now what" to a clear, written plan for how your wealth is structured and who runs it. For nine years I ran a £200M+ single-family office from the inside. That experience, working directly for you.

Why me

I am not a founder telling you I have felt what you are feeling. I am 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 have 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 is 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 are 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 have 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.

The Framework

6 Critical Areas of Post-Exit Wealth

A complete foundation from the morning after signing to building multi-generational wealth.

01

Exit & Transition

Your first 90 days. What to do. What NOT to do. The decision framework for immediate actions and the 12-month no-major-commitments rule.

02

Finance & Tax Planning

Structuring wealth for long-term preservation. Keeping what you earned across jurisdictions. Sustainable income planning.

03

Estate Planning & Legacy

Protecting what you have built for the next generation. Family governance, charitable structures, and wealth transfer strategies.

04

Lifestyle & Identity

The identity crisis nobody prepares you for. The emotional arc. Relationship impacts. Building your next chapter with intention.

05

Risk & Diversification

Escaping concentration risk. Diversification frameworks. Hedging strategies. The behavioral traps that catch even the sharpest operators.

06

The Family Office

Do you need one? Three models explained. Structure, staffing, governance, and a full cost analysis and break-even by AUM.

How It Works

A structured path from uncertainty to confidence across every dimension of post-exit life.

Who Is Behind PostExitWealth

Over 13 years working alongside founders and entrepreneurs, I have 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 are different. You have 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 is 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.
