Are Search Funds a Good Investment? Returns Analyzed
14 min read
Search funds have generated a 33% aggregate pre-tax IRR across 681+ funds since 1984, making them one of the highest-returning alternative asset classes. But averages mask significant dispersion, about a third of investments lose money. This article analyzes the data investors need to evaluate search fund allocations.
Historical returns
Based on the Stanford GSB 2024 study and IESE’s international data:
US search funds (Stanford 2024)
- Aggregate pre-tax IRR: 33.0% (all funds 1984-2022)
- Aggregate MOIC: 5.5x invested capital
- Median pre-tax IRR: 18.7% (important: the median is much lower than the mean)
- Median MOIC: 2.4x
- Return on search capital only: ~11% of search investments return 10x+, driving overall returns
International search funds (IESE 2024)
- Aggregate pre-tax IRR: 26.7%
- Growing rapidly: International funds have grown from <5% to 40%+ of new fund formation
- Regional variation: Europe, Latin America, and Canada each show different return profiles
Return distribution: the J-curve of outcomes
- ~33% lose money: These investments return less than 1.0x, including total losses
- ~33% return 1-3x: Modest returns, roughly comparable to public equities
- ~33% return 3x+: The home runs that drive aggregate returns, with top decile returning 10x+
This power-law distribution means portfolio construction matters. Single-fund investing carries significant risk; diversified search fund portfolios (10+ investments) more reliably capture the asset class returns. According to Cambridge Associates’ 2024 benchmark data, a portfolio of 15+ search fund investments has historically converged on the asset class average, reducing the probability of a below-1x portfolio return to under 5%.
Comparison to other asset classes
- S&P 500: ~10% annualized returns. Search funds deliver 3x this return with significant illiquidity premium
- Private equity (buyout): 15-20% net IRR for top-quartile funds. Search funds outperform on IRR but with smaller absolute check sizes
- Venture capital: 20-30% for top-quartile funds. Similar return profile but search funds invest in profitable businesses, not pre-revenue startups
- Real estate: 8-15% total returns. Lower risk, lower return, more liquid. See ETA vs. real estate
What drives search fund returns?
The searcher
- The single most important factor. The quality, drive, and judgment of the CEO/searcher determines outcomes
- Investor evaluation of the searcher is the primary investment decision
- Track record of the searcher’s pre-ETA career is a leading indicator
The business acquired
- Target quality: Recurring revenue, low concentration, existing management layer
- Entry valuation: Overpaying is the #1 cause of search fund failure
- Industry dynamics: Tailwinds (growing market, succession wave) vs. headwinds (disruption, commoditization)
Value creation levers
- Organic growth: Revenue growth through sales/marketing investment
- Buy-and-build: Add-on acquisitions to scale the platform (highest-returning strategy when executed well)
- Operational improvement: Margin expansion through process improvement and technology
- Multiple expansion: Growing EBITDA above $5M often commands 2-3 higher turn multiples at exit
The investor economics
See our detailed investor economics guide for the full structure:
- Search phase investment: $30K-$50K per unit (typically 10-20 investors contribute $400K-$600K total)
- Step-up conversion: At acquisition, search capital converts at 1.5x, meaning $30K buys $45K worth of acquisition equity
- Pro-rata right: Investors have the right (not obligation) to invest pro-rata in the acquisition equity
- Preferred return: Some structures include preferred return provisions before common equity participation
Risks investors should understand
- Search risk (33%): One-third of searchers never complete an acquisition. Search capital is lost
- Acquisition risk: Overpaying, missing DD red flags, or acquiring a concentrated business
- Operator risk: First-time CEO managing through unexpected challenges (recession, key employee departure, customer loss)
- Illiquidity: 5-7+ year hold period with no secondary market
- Small check sizes: $30K-$50K search investment + $200K-$500K acquisition equity. For large allocators, deploying meaningful capital requires many investments
Who should invest in search funds?
- Former search fund entrepreneurs: Know the model, can evaluate searchers, often mentor their investments
- Family offices: Long-horizon capital, can build diversified search fund portfolios over time
- High-net-worth individuals: $30K-$50K per search fund fits angel/venture allocation budgets
- Fund-of-funds: Specialized vehicles (e.g., Pacific Lake Partners, Relay Investments) that aggregate search fund investments
- MBA school communities: Stanford, HBS, and other programs have active investor networks
Notably, IESE’s 2024 International Search Fund Study shows that international search fund investing is growing rapidly, with funds outside the US now comprising over 40% of new fund formation. Investors with global mandates can diversify across geographies while tapping into the baby boomer succession wave that is creating acquisition opportunities worldwide.
Frequently asked questions
What is the average return on search fund investments?
The aggregate pre-tax IRR is 33% with a 5.5x MOIC (multiple on invested capital), per Stanford’s 2024 study. However, the median return is much lower at 18.7% IRR and 2.4x MOIC, because returns are driven by the top ~10% of investments that return 10x or more.
How risky are search fund investments?
Approximately one-third of search fund investments lose money. Key risks include search risk (33% of searchers never acquire), operator risk (first-time CEO managing through challenges), illiquidity (5-7+ year hold), and small check sizes. Diversified portfolios of 10+ investments more reliably capture the asset class returns.
How do search fund returns compare to private equity?
Search funds have outperformed traditional PE buyout funds on an IRR basis (33% vs. 15-20% for top-quartile PE), though with smaller absolute check sizes and higher dispersion. Unlike PE, search funds invest in profitable businesses at 4-6x EBITDA and rely on operational improvement rather than financial engineering for value creation.
