A founder can appear to be worth tens of millions and still depend on salary for next year's school fees. The contradiction is not unusual. Private-company value is quoted as a headline, while personal life runs on cash, legal rights and decisions that can actually be executed.
The planning mistake is treating one valuation as if it were already a diversified family balance sheet. It is neither. It is an uncertain claim on a company, shaped by documents, preferences, vesting, buyers, tax, timing and the founder's own ability to sell.
Six numbers hiding inside paper wealth
1. Headline valuation. This is the number attached to the company in a funding round, internal mark, offer or press story. It may refer to the value of the whole company on a particular set of terms.
2. Legal ownership. The cap table shows shares, options or other rights, but share classes, preferences, dilution and company documents affect what that ownership means.
3. Vested value. Unvested options, service conditions, exercise prices and leaver provisions can reduce what is currently owned or exercisable.
4. Saleable value. Private shares do not become liquid because a spreadsheet assigns a price. Transfers can require consent, a permitted secondary sale, an IPO or an acquisition. Investor.gov's private-placement guidance notes the limited liquidity and resale constraints common to private securities.
5. After-tax liquidity. Gross proceeds can be reduced by tax, transaction costs, escrow, holdbacks, debt repayment and currency conversion. Cross-border residence, employment and source questions may split the analysis between countries.
6. Sustainable personal capital. Cash in an account is still not a spending rule. Near-term commitments, retained company exposure, risk capacity, family goals and the cost of the intended lifestyle determine how much can safely be treated as durable personal capital.
Putting ranges around all six is more honest than multiplying a funding-round price by a share count.
Concentration is financial and emotional
The SEC identifies inadequate diversification as a risk pattern because concentration increases exposure to one investment. Its investor behaviour material is general rather than founder-specific, but the principle is especially visible when employment, identity, reputation and net worth all depend on the same company.
That does not make an immediate sale automatically correct. A founder may have contractual restrictions, tax consequences, information advantages, control objectives or strong conviction about future value. It does mean the concentration should be measured across the whole household.
Questions worth quantifying include: What percentage of family wealth depends on the company? How much annual spending depends on salary from it? Are property, guarantees or loans also linked to the business? What happens if an exit takes five years rather than one? Emotional attachment is not a spreadsheet error, but it should be named rather than disguised as objective portfolio theory.
The liquidity-event dependency map
A transaction is a chain of dependencies. A secondary sale can require board or investor consent. An IPO can involve lock-ups and restricted securities. Investor.gov's IPO overview explains that founders or management may be selling shareholders and that saleability can remain constrained after listing.
An acquisition can include rollover equity, earn-outs, escrow and warranties. Option exercise can require cash before proceeds arrive. A tender offer may cover only part of a holding. Each mechanism changes the amount, date and certainty of personal liquidity.
Create a dependency map with a named owner for corporate approvals, tax analysis, legal documents, banking readiness and the family decision. It should show the last date on which a decision remains reversible.
Residence, vesting and transaction timing
Moving country near a liquidity event creates more questions, not an automatic tax answer. Personal residence may change during the transaction. Employment-related securities can look to where duties were performed over a relevant period. Company management may move in practice even when incorporation does not.
For UK-connected founders, HMRC's Statutory Residence Test guidance is one part of the evidence framework. Destination-country residence, source rules and treaty provisions must be analysed separately.
The planning record should distinguish commercial reasons, family reasons and tax analysis. A move that exists only in paperwork is fragile. A genuine family move can still have poor tax timing. Neither point determines the outcome alone.

The source-of-wealth file banks will ask for
Liquidity can arrive faster than a private bank is prepared to receive it. A strong source-of-wealth file tells the history of the value and a source-of-funds file explains this specific payment.
The file may include incorporation records, historic cap tables, subscription and option documents, funding rounds, shareholder agreements, board approvals, the sale agreement, completion statement, escrow terms, tax advice and bank statements showing the path of proceeds. Where the founder has changed address or tax residence, those records should be current before the transfer.
A one-page chronology helps institutions understand the documents. It should be factual and consistent, not promotional. The reason is operational: an unexplained eight-figure transfer can be delayed even when every pound or euro is legitimate.
Turning a windfall into a family balance sheet
The post-transaction question is not simply where to invest. First identify what the money must do.
Separate near-term tax and transaction liabilities, an operating reserve for household commitments, any capital allocated to a new venture, property plans, gifts or philanthropy, long-term family capital and truly discretionary risk capital. Currency matters when future spending is in euros but proceeds arrive in sterling or dollars.
Governance matters too. Who can see the balance sheet? Who can authorise payments if the founder is unavailable? Are wills, powers of attorney and succession instructions aligned with new accounts and countries? A portfolio can be well diversified and still be badly governed.
There is no universal allocation. The useful output is a documented set of purposes, time horizons, decision rights and review dates.
Composite scenario: a partial secondary sale
A UK founder living between London and Lisbon is offered a secondary sale of 12% of the founder's holding. Half the options are vested. The company expects another funding round, the family wants a Portuguese home and the founder is considering moving before completion.
The headline valuation is only the first number. The legal documents determine which shares can transfer. The exercise cost and tax need funding. Residence facts must be tested in both countries. The bank needs the ownership and transaction history. The family needs to decide how much liquidity removes risk without turning a company transaction into an oversized property commitment.
The scenario has no generic best answer. It has a series of decisions that can be costed, sequenced and documented.
A ninety-day founder workplan
Days 1-30: Reconcile the cap table, vesting, exercise costs, share classes and transfer restrictions. Build a personal balance sheet and a residence calendar. List known transaction paths without assigning certainty to any of them.
Days 31-60: Commission coordinated tax and legal analysis for the company, the founder and the destination country. Prepare the source-of-wealth file. Agree family objectives, minimum liquidity and unacceptable outcomes.
Days 61-90: Test banking capacity, transaction cash flows and currency needs. Record which decisions are conditional on advice. Create a post-completion control list for tax reserves, account authority, estate documents and investment governance.

- How would a move affect personal residence, employment-related securities or company management?
- Which proceeds could be delayed, retained or contingent?
- What documents will banks and future advisers need to verify the wealth?
- Which household commitments depend on an uncertain transaction?
- How will the family govern cash, investments and access after completion?
FAQ
Is a company valuation the same as personal wealth?
No. It does not account for ownership, vesting, preferences, dilution, tax, sale restrictions, transaction costs or whether a buyer exists.
When should a founder start personal liquidity planning?
Before a transaction is certain, while residence, records, family goals and transaction choices can still be examined without a completion deadline.
Is diversification always the first move after an exit?
There is no universal sequence. Tax, lock-ups, cash needs, risk capacity, retained business exposure and personal goals all affect the decision.
