How University Endowments Build Their Venture Allocations

University endowments are among the most respected investors in venture capital. Many have backed leading venture firms for decades, and their long time horizons make them natural investors in an asset class where returns take years to arrive.

The best-known approach is the "Yale model", developed under David Swensen, Yale's chief investment officer from 1985 until his death in 2021, which emphasised diversification into alternative assets such as venture capital and private equity. This guide explains how endowments approach venture investing, why they have been so influential, and what other investors can learn from them.

1. Why Endowments Suit Venture Capital

• Perpetual time horizon. Endowments aim to support their institutions indefinitely, so they can accept illiquidity for higher long-term returns.
• Predictable spending. Most spend a set percentage of assets each year, often around 4% to 5%, which allows them to plan liquidity needs.
• Long-standing relationships with top venture firms, sometimes spanning decades, giving them access others lack.
• Professional investment teams dedicated to manager selection and portfolio construction.

2. How Endowments Build Their Allocations

1. Set a target allocation to venture capital as part of a broader private markets strategy.
2. Plan commitment pacing, spreading commitments across vintage years to avoid concentration in any one market cycle.
3. Select managers carefully, focusing on track record, team stability, strategy and alignment.
4. Build long-term relationships, often re-investing with strong managers across many funds.
5. Back some emerging managers to find the next generation of top performers early.
6. Monitor and rebalance, adjusting commitments as valuations and market conditions change.

3. Recent Pressures on Endowments

• The denominator effect. When public markets fall, private holdings can become a larger share of the portfolio than intended, limiting new commitments.
• Slow distributions. Fewer exits mean less cash returned, while capital calls continue. See DPI vs. TVPI.
• Higher taxes. A 1.4% excise tax on the investment income of wealthy private universities was introduced in 2017, and a 2025 federal law raised rates for the largest endowments.
• Liquidity management. Several prominent endowments reportedly explored selling private fund stakes on the secondary market in 2025 to raise cash and rebalance. See the LP secondary market.

4. Lessons for Other Investors

• Think long-term. Venture returns take years; consistent commitments across cycles matter more than timing the market.
• Pace commitments across vintage years for diversification.
• Prioritise manager quality and long-term relationships.
• Plan for liquidity, including capital calls and slower distributions.
• Be realistic about access. Endowments' advantages come from decades of relationships that newer investors cannot replicate quickly.

5. What Endowments Mean for Founders and GPs

For fund managers, endowment LPs are valuable, stable partners and a strong signal to other investors. They typically expect rigorous reporting, clear strategy, alignment and strong governance. Emerging managers often find endowments selective but influential once they commit.

Frequently Asked Questions

What is the Yale model?

An investment approach associated with David Swensen at Yale that emphasises diversification into alternative assets such as venture capital, private equity and real assets, supported by a long-term horizon.

How much do endowments allocate to venture capital?

It varies widely by institution and strategy. Some of the largest endowments have significant allocations to venture and private equity combined.

Why do endowments sell fund stakes on the secondary market?

To raise liquidity, rebalance their portfolios or reduce exposure to certain managers or vintages.

Can individual investors copy the endowment model?

Partially. The principles of long-term thinking, diversification and pacing apply, but access to top managers is harder for smaller investors.
