Venture Sits on Top of the Wealth the Family Already Owns
Venture is one part of the family's wealth, alongside its operating business, property and other investments. When much of that wealth is already hard to sell, the family has less room for another long-held asset than the venture percentage alone suggests.
The 2025 RBC and Campden Wealth North America Family Office Report shows how common large private-market holdings are among family offices.
In the survey, 88% of North American offices held private-market assets. Those assets made up 29% of the average portfolio in 2025. A new venture commitment adds to the cash already tied up in those holdings.
A sample family wealth allocation assigns twenty five percent to venture and thirty five percent to liquid assets. Real assets receive twenty five percent. Liquidity reserves receive the remaining fifteen percent.
When Venture Becomes a Family-Wealth Decision
At 25% of family wealth, venture becomes a major part of the balance sheet. Its losses, cash calls and exit timing can affect decisions well beyond the venture programme.

| Portfolio segment | Share | How to read it |
|---|---|---|
| Venture capital | 25% | Meaningful growth allocation that needs governance and diversification. |
| Liquid assets | 35% | Public securities and cash-like assets supporting flexibility. |
| Real assets and operating interests | 25% | Property, operating company, or other long-term family assets. |
| Liquidity reserve | 15% | Cash for commitments, distributions, taxes and unexpected needs. |
What a Loss or Delay Could Change for the Family
A 5% venture allocation can be excessive when the rest of the wealth is tied to one private business. A 25% allocation may be manageable for a diversified family with strong liquidity and a long horizon.
What matters is what happens when exits take longer than expected. If the family would have to sell other assets or miss commitments, the venture position is too large for the balance sheet around it.
The Whole Private Balance Sheet Matters
| Family position | Venture capacity may be higher when | Capacity may be lower when |
|---|---|---|
| Operating business | Business cash flow is stable and unrelated to venture holdings | Most wealth and income depend on one private company |
| Liquid assets | Calls can be funded without selling at a bad time | Liquid reserves are small relative to commitments |
| Family spending | Needs are predictable and modest | Large distributions, taxes, or purchases are near |
| Time horizon | Capital can remain invested across generations | Liquidity is needed within a few years |
One Company Can Appear Through Several Vehicles
A family may own one business through a venture fund and an SPV, then add a direct holding. Three legal positions still create one company risk.
Taken together, those holdings can reveal more sector, manager or company risk than any single report shows. Direct deals may increase dependence on one company faster than the overall venture share suggests.
Both Losses and Winners Can Create Concentration
A downside case can assume that part of the venture book is lost and the rest returns cash late, while existing capital calls continue. The strain appears when the family cannot meet its other needs without a forced sale.
Success can also concentrate wealth. If one company grows into a large share of the family's assets, selling part of it may matter more than chasing the highest final multiple. Estate planning may also become more pressing.
Ways to Manage a Material Allocation
- Vintages across several market cycles reduce reliance on one entry period.
- Company limits cover more of the actual risk when they include direct stakes and holdings through funds.
- Liquid assets provide a source of cash for firm capital commitments while exits remain uncertain.
- Secondaries can allow later entry or earlier sale. Their benefit depends on the price and terms, as well as how the transaction changes the portfolio.
- A partial sale can reduce the family's dependence on a winner that has grown into a large share of its wealth.
The size of the allocation determines how much a strong venture result can help the family. It also affects how much freedom remains for other financial choices in a weak market.
What the Percentage Bands Mean in Dollars
For a $500 million family office, 5% in venture is $25 million. A 15% allocation is $75 million, while 25% requires $125 million. Those dollars are easier to compare with family spending and future calls.
RBC and Campden reported that private markets represented 29% of the average North American family-office portfolio in 2025. The venture decision sits inside that broader private allocation.
Other Illiquid Assets Add to the Constraint
A family with 40% of its wealth in a business and property reaches 65% in hard-to-sell assets after adding 25% in venture. Buyout funds and restricted shares can raise the share further, while unpaid commitments create more future cash claims.
For a $500 million family office, venture allocation of 5%, 15%, and 25% equals $25 million, $75 million, and $125 million.
Venture Concentration on a $500M Family Balance Sheet
The move from 5% to 25% turns venture from a satellite allocation into a major portfolio that needs timing and governance.

| Venture share of family wealth | Assumed family wealth | Venture dollars | Portfolio implication |
|---|---|---|---|
| 5% | $500M | $25M | Smaller allocation with manageable timing. |
| 15% | $500M | $75M | Requires formal allocation policy. |
| 25% | $500M | $125M | High concentration and liquidity sensitivity. |
How Concentration Limits Support Family Liquidity
A smaller portfolio may need pooled funds to spread its risk. A larger one may support direct fund relationships and selected deals. Both depend on cash left outside venture: reserves and planned family spending can fall due before any exits occur. That timing determines how much freedom the family has to respond to change.
Frequently Asked Questions
Is a 25% venture allocation always too high?
A 25% allocation may fit a family with strong liquidity and aligned governance. The same target can be unsafe when most wealth already sits in one private business.
Should family offices count direct startups separately from funds?
Separate records for direct startups and funds make each holding's risks easier to see. Together, they show total venture exposure. A direct stake usually adds more dependence on one company and its later funding needs.
