Ten Percent Can Mean One Fund or an Investment Platform
The same venture percentage buys different programmes for families with $100 million, $500 million or $5 billion. More dollars allow more managers and vintage years. They also require more staff, cash planning and reports that show holdings through every route.
The UBS Global Family Office Report 2025 shows how large single-family offices invest across several markets. Its averages describe those families. They are not targets for another family.
UBS surveyed 317 offices with average family net worth of $2.7 billion and average office assets of $1.1 billion. Those figures describe the sample. The commitments and work created by a venture target depend on each family's own size and holdings.
A sample family office portfolio allocates fifteen percent to venture and thirty five percent to other alternatives. Public and liquid assets receive thirty five percent. Cash and reserves receive the remaining fifteen percent.
A Scaled Family Office Allocation
As a family office grows, venture can be combined with other alternatives and liquid assets instead of sitting as a one-off investment.

- Other alternatives35%
- Public and liquid assets35%
- Cash and reserves15%

| Portfolio segment | Share | How to read it |
|---|---|---|
| Venture capital | 15% | Dedicated venture programme across funds, SPVs, co-investments, or secondaries. |
| Other alternatives | 35% | Private equity, real assets, credit, hedge funds, or other private strategies. |
| Public and liquid assets | 35% | Liquid assets that support spending and portfolio rebalancing. |
| Cash and reserves | 15% | Capital reserved for taxes, distributions, commitments, and opportunities. |
Scale Expands the Available Routes
A smaller office may need pooled access or a focused group of funds because manager minimums consume much of the allocation. At $500 million, the family can build across several vintages. At $5 billion, direct relationships and co-investments can sit beside secondaries and internal staff.
More routes widen the choice without setting the amount to invest. Family payments, taxes, business needs and other private assets all compete with venture for cash.
What Scale Makes Possible
| Family office assets | Possible approach | Main constraint |
|---|---|---|
| $100M | Fund of funds, pooled access, or a few direct funds | Minimum commitments and concentration |
| $500M | Direct fund relationships across vintages with selective SPVs | Building process before deal flow grows |
| $5B | Dedicated mandates, co-investments, secondaries, and internal staff | Deploying large capital without lowering quality |
What Annual Programme Does the Target Require?
Ten percent becomes $10 million, $50 million or $500 million at the three example sizes. The smallest programme may support only a focused group of direct funds. The largest may need several investment structures to deploy without lowering quality.
A target range describes the intended holding over time; a yearly pace describes how commitments build toward it. The two can differ sharply from current NAV because money promised to funds may remain uncalled for years.
Access Creates Work Before It Creates Value
A larger office may gain better manager allocations and more co-investment invitations. That access brings reports, calls and direct company decisions too. Staff and process capacity affect how much of it the family can use well.
A larger cheque can magnify the mistakes of an informal decision process.
What Shapes the Family's Programme
- A goal based on returns, learning, strategic access or a mix gives the programme its purpose.
- Cash for family distributions, taxes and business needs limits the venture budget.
- Funds, pooled vehicles, SPVs, co-investments and direct deals each place different demands on the team.
- Growth across market cycles reduces dependence on one entry period.
- The roles assigned to family members, the committee and staff determine how investment decisions are made.
Together, those choices define a programme the family can run. Scale adds value when wider access remains within its limits on cash and oversight.
The Same Policy Produces Different Dollars
A 10% venture target gives a $100 million office $10 million to deploy. The same target creates $50 million at a $500 million office and $500 million at a $5 billion office.
UBS reported that private markets averaged 21% in 2024 among surveyed offices. Respondents planning changes in 2025 intended to move to 18% on average, showing that even large family offices adjust private exposure over time.
Manager Count Changes With the Dollars
At a $10 million fund minimum, a $10 million allocation supports 1 relationship. A $50 million allocation supports 5, while $500 million could support 50 equal commitments before reserves. The arithmetic shows why larger offices need a portfolio design tailored to their own balance sheet.
A 10% venture allocation creates $10 million, $50 million, and $500 million of venture capital across $100 million, $500 million, and $5 billion family offices.
Venture Capacity at Different Family-Office Sizes
The same 10% allocation becomes a one-fund allocation at $100M and a full institutional portfolio at $5B.

How the Team's Capacity Shapes the Structure
A small portfolio may rely on pooled funds; a larger one may support direct relationships and selected deals. Reserves and future cash needs limit either mix and determine how much room the family retains to change course.
More Capital Creates Pressure to Use Every Route
A large office has access to funds, company vehicles and secondaries. A core route gives the programme a base; the others can serve specific purposes around it. Without those roles, more choice can leave the portfolio harder to understand.
Funds provide manager-led breadth. Direct deals add company exposure where the family has knowledge, and secondaries can change timing. These different roles explain why a family might combine the routes rather than put more money into the same one.
Frequently Asked Questions
Should every family office use the same venture percentage?
Liquid assets and existing private holdings limit how much venture the family can bear. Team capacity limits how much it can oversee. A peer's percentage may reflect a very different balance of those needs.
When does a family office become institutional in venture?
An office meets an institutional standard when staffing, approvals and monitoring keep pace with the money invested. A large cheque alone does not make informal decisions more sound.
