What is a search fund? A search fund is a pool of capital that backs an operator to spend about 20 months finding a profitable, established small business, buy it and run it as CEO, and investors fund the search first and then get the right to fund the acquisition. Stanford Graduate School of Business has tracked the model since 1984, and its 2026 study reports an aggregate IRR of 33.9% and a 4.75x return on invested capital across 862 core search funds.
If you've written angel checks or you're holding proceeds from a business you sold, search funds offer private company upside with profitable businesses at the centre instead of startups. The catch is that the returns are concentrated in a few big outcomes, so how you invest matters as much as whether you do, and this guide walks through the model, the real numbers and the three ways individuals and family offices get exposure.
How does a search fund work, start to finish?
There are four stages, and they don't take equal amounts of capital or time, so it helps to see where your money actually goes before you look at any returns.
Stage one: the raise. A searcher raises a modest search fund from a group of investors to pay a salary and cover deal costs while they look, and those investors usually get the right, but not the obligation, to invest in whatever company is eventually acquired, often on preferential terms.
Stage two: the search. The searcher spends the next stretch calling owners of profitable, established businesses in fragmented industries, and Stanford reports that the median search fund acquired a company after 20 months, though most conversations go nowhere and plenty of deals die in diligence.
Stage three: the acquisition. When the searcher finds a company, they come back to the investor group to fund the purchase, usually alongside bank debt or seller financing, and Stanford reports a median purchase price of $16.0 million in 2024 and 2025 at a median multiple of 6.2x EBITDA.
The search check is small, and the acquisition check is the real position, which is why the most important decision you make as a search fund investor is usually the follow-on one.
Stage four: operate and exit. The searcher becomes CEO and runs the business for several years, usually growing revenue, professionalising operations and building a management team the previous owner never needed, before selling to a private equity firm or a strategic buyer or, in some cases, holding for much longer.
Stanford's 2026 study added data on 67 of these long-hold structures, often called long duration enterprises, although it doesn't calculate returns for them yet.
What kind of companies do search funds buy?
Among companies acquired since 2020, Stanford found the typical search fund target had a 25% EBITDA margin and 30 to 40 employees and sold for 6 to 7x EBITDA, with services, software and education the top industries searchers targeted in 2024 and 2025.
The median first-year base salary for a newly installed search fund CEO was $208,000, which gives you a sense of the scale involved, since these are real operating companies with real payrolls rather than early-stage experiments.
What do search fund returns actually look like?
The headline is an aggregate 33.9% IRR and 4.75x ROI across 862 core search funds with data through December 31, 2025, and Stanford also reports a public market equivalent of 2.88, meaning search funds as a group earned nearly three times what the S&P 500 returned over matching periods.
Those are historical, aggregate, pre-tax figures built from every investor contribution and distribution in the dataset, so they're not projections, they're not net of any fund's fees and they're not any individual manager's results, and anyone who quotes you the IRR without saying so is selling rather than explaining.
Underneath the headline sits a wide distribution, because the overall acquisition rate for concluded search funds is 58%, and for funds that started between 2021 and 2024 and have concluded it's 48%, meaning roughly half of recent searches never buy a company.
Of the searches that did acquire, 74% reported some gain in value and 26% reported a loss, and 61% of those losses were partial rather than total, while about two thirds of the gainers returned 1 to 5x and the rest returned more than 5x.
The biggest outcomes carry the aggregate, since excluding funds that returned 10x or more drops it to 2.8x and a 27% IRR, and excluding the top 10% of funds drops it to 2.1x and a 20% IRR.
What this means for how you invest in a search fund
A single search fund position leaves you exposed to one operator, one company, one industry and one moment in the market, and with half of recent searches never acquiring, a concentrated portfolio is mostly a bet on landing one of the rare outliers.
Owning more positions only helps if the diversification is meaningful across searchers, managers, industries and vintages, and that's hard to build one search at a time, which is the main reason structure matters so much in this asset class. The same idea shows up when LPs read why invest in emerging managers in venture: breadth and process usually beat a handful of one-off bets.
How individuals and family offices get search fund exposure
You have three real choices, and they carry very different workloads, so the right one depends mostly on how much time and diligence you can give it each year.
Option one: back individual searchers. You join a searcher's investor group directly and reserve capital for the acquisition, which gives you the most control and the best economics, but it's effectively a second job of sourcing searchers, reading deal materials, making follow-on decisions inside short windows and sometimes sitting on boards.
The strongest searchers are also often oversubscribed by investors who've backed them before, so a newcomer who picks searchers one at a time is frequently choosing from what's left after the repeat investors have taken their allocation.
Option two: invest deal by deal through syndicates. A syndicate or SPV lets you skip the search stage and invest directly in a specific acquisition once it's identified, so you see the company, the financials and the price before you commit, although you're only seeing the deals someone else chose to syndicate.
Option three: invest through a diversified fund. A fund that invests across many search fund managers, with selected direct investments alongside them, gives you the breadth this asset class needs without the second job, through one commitment that spreads exposure across experienced managers, their searchers and the companies they acquire.
An example of a diversified search fund path
One example of that diversified path is Agate Hound, a fund that invests primarily through underlying search fund managers, with selected direct investments alongside them, and it isn't a search fund itself. Managing partner Jon Staenberg and operations and finance partner Joel Mezistrano at Agate Hound work from the manager-selection side of the ecosystem, which is a different job from running a single search.
For an individual or family office, that distinction is the diligence point: you're evaluating access, diversification and reporting across many positions, not underwriting one searcher's next LOI.
What ETA means and why you'll hear both terms
Entrepreneurship through acquisition, usually shortened to ETA, is the broader category, covering everyone who buys an existing business instead of starting one, including self-funded buyers, independent sponsors and traditional search funds.
Search fund is the older and more specific term, and it's still the phrase most investors use, while ETA is the term business schools teach, and you'll also hear this corner of the market called microcap PE because the companies are real private equity targets, just far smaller than the ones big buyout funds chase.
How this compares to angel investing
If you've written angel checks, the first difference you'll notice is that the company is already profitable, so you're buying revenue, customers and cash flow that already exist rather than funding a search for product market fit.
The entry price is also grounded in earnings, since search fund acquisitions are priced on cash flow at a median 6.2x EBITDA in 2024 and 2025, not on revenue multiples or a story about the future.
The failure mode is different too, because startups usually fail by running out of money before finding demand, while search fund companies usually struggle because the operator was the wrong fit, a customer concentration problem went unnoticed or the debt was too heavy for a soft year.
What Stanford says predicts a successful search
Stanford's 2026 data shows that searchers with more than two years of post-graduation experience acquired at a 55% rate against 40% for those with a year or less, and partnered searches acquired at 58% against 43% for solo searchers.
Searchers who signed a letter of intent within their first six months acquired at a 74% rate, and these are correlations rather than guarantees, but they give an individual investor a concrete starting checklist when meeting a searcher for the first time.
Why AI could matter more for small businesses than for anyone else
Small businesses have historically adopted new technology more slowly than large companies, and that lag is exactly why they may have the most relative upside from AI, because a new CEO who understands the tools and controls the P&L can apply it to pricing, customer service, scheduling and the back office within months.
That's a forward-looking thesis rather than proven return data, and nobody has a clean dataset yet on AI's effect on search fund outcomes, but it's one of the reasons we think this asset class is worth a fresh look now.
What are the main risks in a search fund?
The search may not find anything, and with a 48% acquisition rate for recently concluded searches, roughly half of search capital buys nothing at all, so size that first check carefully and expect that some searches won't convert.
One person carries the company, usually a first-time CEO learning on the job without a co-founder, and any leadership transition at a small business needs careful management by the board.
Debt amplifies mistakes, because most acquisitions are financed partly with borrowing, so a soft year hurts more than the purchase price suggests, and small businesses are exposed to local economies, labour costs and customer concentration in ways a diversified public portfolio isn't.
Your money is also locked up for years, since this is private equity with no active secondary market, and CEOs in Stanford's latest study held their companies longer than in the previous one, so plan on a long horizon before you see distributions.
Questions to ask before you invest in a search fund
For an individual searcher, ask what they've operated before, how they'll screen companies, who else is in the investor group, how much of their own money is in, what happens if the search doesn't convert and how much debt they expect to use, because experienced search investors on the cap table are both a quality signal and a source of help when a deal gets hard.
For a diversified fund, ask how many underlying managers and direct positions it holds, what its access to strong managers and searchers actually is, how direct investments get chosen, how much the GP has committed and how it reports on a portfolio of private operating companies.
Frequently asked questions
How does a search fund work?
Investors back an operator to find and buy one profitable small business, funding the search first and then getting the right to invest in the acquisition, after which the searcher becomes CEO and typically runs the company for several years before a sale.
Are search fund returns really above 30%?
Stanford GSB's 2026 study reports an aggregate IRR of 33.9% and a 4.75x ROI across 862 core search funds since 1984, but that's a historical, pre-tax figure, and excluding the top 10% of funds it falls to a 20% IRR.
What kind of companies do search funds buy?
Profitable, established small businesses, typically with about a 25% EBITDA margin and 30 to 40 employees, and Stanford reports a median purchase price of $16.0 million in 2024 and 2025, mostly in services, software and education.
How long until I see money back?
Plan on a long horizon, because acquiring a company typically takes around 20 months, and CEOs usually hold the business for several years before an exit.
Is it better to invest in one searcher or a fund?
It depends on how much time and diligence you can give it, since backing individual searchers gives you control but concentrates risk in one operator, while a diversified access fund spreads exposure across managers, searchers, industries and vintages in one commitment.
