Net Worth Can Overstate the Capital Available for Venture
A $500 million net worth does not mean a family has $500 million available for venture commitments. If most wealth sits in an operating business, property or other private assets, far less cash may be available for capital calls. That gap between wealth and usable cash limits venture capacity.
Those existing assets already consume part of the family's illiquidity budget, so venture belongs inside the whole alternatives review. The Goldman Sachs 2025 Family Office Investment Insights Report offers a useful reference.
Goldman reported 42% alternatives exposure in 2025. Private equity accounted for 21%, while private real estate and infrastructure represented 11%; private credit added 4%. These assets already make claims on liquidity that venture would share.
A sample family office balance sheet shows venture capital at twenty percent, other illiquid assets at sixty percent, and liquid assets at twenty percent.
Illiquidity Has More Than One Source
A family office can carry meaningful venture exposure when it understands the whole illiquid asset base and keeps enough liquid capacity.

| Portfolio segment | Share | How to read it |
|---|---|---|
| Venture capital | 20% | Illiquid growth exposure requiring patience and monitoring. |
| Other illiquid assets | 60% | Operating businesses, real estate, private equity, credit, or other long-hold assets. |
| Liquid assets | 20% | Liquidity available for spending, taxes, capital calls, and flexibility. |
How Illiquidity Relates to Cash Flow
A high illiquid share may work when recurring cash flow is strong, spending is modest and the family can wait a long time. Current illiquid assets and uncalled commitments together show how much wealth is tied up compared with cash needs in a weak period.
Twenty Percent and Eighty Percent Are Different Ways of Working
| Illiquid share | Possible position | Main requirement |
|---|---|---|
| 20% | Most assets remain available for calls and spending | Basic pacing and concentration limits |
| 50% | Private assets are a major return source | Multi-year cash forecasting and carefully planned commitments |
| 80% | The balance sheet is built around long-held private wealth | Strong recurring cash flow, low forced-sale risk, and clear family policy |
The percentages show three ways to run the portfolio. Each needs limits suited to the family. The same venture cheque may work for a family with steady cash coming in. It may be too much for one whose wealth is mostly on paper.
The Operating Business Can Fund Calls and Create the Main Risk
A profitable family business may fund calls for years. It can also be the family's largest asset that is hard to sell. If it and the venture holdings rely on the same economic cycle, both risks can rise at once.
The family business belongs in this picture because it can supply cash or absorb it.
Consider $500 million of family wealth, including a $300 million business and $100 million of private real estate. A $50 million venture programme is 10% of net worth but consumes half of the remaining $100 million liquid pool before taxes or spending.
The business may also need capital during the same weak market in which venture funds issue calls and exits slow. In that case, assets the family can actually use matter more than the appraised balance sheet.
Uncalled Commitments Convert Future Liquidity Into Private Assets
The current asset mix may look comfortable while the office carries large fund obligations. Each call reduces the liquid pool and increases the private position. A period with no venture distributions and weaker business cash flow shows how those pressures can combine.
Ways to Support a Larger Venture Programme
- A liquid reserve covers existing capital commitments without relying on new exits.
- Several vintages spread calls and possible exits across cycles.
- Secondaries can improve cash-flow timing when the investment starts later in the asset's life.
- Cash earmarked for family entities is already spoken for, even if it remains in the bank.
- A pause rule links slower new commitments to a decline in liquid coverage.
A high illiquid share can be deliberate. It becomes excessive when ordinary cash needs force the family to borrow under pressure or sell an asset it would otherwise keep.
The Combined Illiquid Portfolio
For a $500 million office, a 20% illiquid share is $100 million. At 50%, the amount is $250 million; at 80%, it reaches $400 million and leaves only $100 million liquid before other obligations.
Goldman reported 42% alternatives exposure among surveyed offices in 2025. Venture is one use of that wider illiquidity budget.
Venture's Share of the Available Capital
If venture receives one-quarter of the illiquid allocation, a 20% private share on $500 million supports $25 million of venture. At 50% total illiquidity, venture becomes $62.5 million; at 80%, it reaches $100 million.
For a $500 million family office, 20%, 50%, and 80% illiquid assets equal $100 million, $250 million, and $400 million of illiquid exposure.
Illiquid-Asset Load and Venture Capacity
A family can still make room for venture alongside other illiquid assets, but it needs larger cash reserves and careful commitment timing.

| Illiquid assets | Dollar amount on $500M | Venture at 25% of illiquid allocation | Liquidity implication |
|---|---|---|---|
| 20% | $100M | $25M | More flexibility for timing. |
| 50% | $250M | $62.5M | Requires formal cash-flow planning. |
| 80% | $400M | $100M | Requires stronger reserve discipline. |
Family Spending Sets a Limit on Venture
Family businesses, yearly spending and known taxes have claims on the available cash. Funds can spread the capital left across more holdings. Individual deals and secondaries make more focused choices within that limit.
Frequently Asked Questions
Can a family office with 80% illiquid assets still invest in venture?
At 80% illiquidity, a family may still have room for venture if cash flow is strong and enough cash remains for known needs. That room shrinks in a weak case where the business and venture holdings both absorb cash at once.
Should venture be counted separately from private equity?
Venture has distinct strategy risks, but it shares the same long-term cash capacity as other private equity. Separate strategy reporting and a combined view of illiquidity answer different questions.
