History of Search Funds: From Stanford 1984 to Today

In 1984, a Stanford professor named H. Irving Grousbeck gave two MBA graduates a radical proposition: raise a small pool of capital, spend up to two years finding one company to buy, then run it as CEO. That experiment produced the first search fund, and the entrepreneur who ran it returned investors more than 24× their money. Four decades later, the model Grousbeck invented has generated over 680 funds in the United States and Canada alone, expanded to 40+ countries, and delivered a 35.1% aggregate pre-tax IRR according to the 2024 Stanford Search Fund Study. This article traces the full arc, from a single classroom idea to one of the highest-returning alternative asset classes in private equity.

The Invention: Grousbeck, Stanford GSB, and the Class of 1984

H. Irving Grousbeck joined the Stanford Graduate School of Business faculty in 1985 and would later co-found its Center for Entrepreneurial Studies (CES) in 1996 alongside Charles Holloway. But the seed was planted earlier. As a professor focused on entrepreneurship, Grousbeck recognized a gap: talented MBA students wanted to lead companies, yet most lacked the capital, the deal flow, or the appetite for startup risk. Traditional paths to ownership, inheriting a family business, climbing to a corporate CEO role, or assembling a used buyout, were either unavailable or required decades of waiting.

Grousbeck’s solution was elegant. A recent graduate would raise a modest fund, typically $150,000 to $400,000, from a small group of investors. That money would cover living expenses and search costs for up to two years while the “searcher” identified, evaluated, and negotiated the acquisition of a single small business. Once a target was found, the same investors (plus new ones) would fund the acquisition. The searcher would become CEO and earn 20-30% of the equity over time, creating powerful alignment between operator and capital. If you’re new to the concept, the what is ETA overview explains the modern version of this structure.

Jim Southern and the First Proof of Concept (1984-1994)

The first person to test Grousbeck’s thesis was Jim Southern, a Stanford MBA from the class of 1983. In 1984, Southern raised roughly $150,000 from professors and friends, money that would fund an 18-month search. He found his target in Uniform Printing, a specialty insurance-document printing company generating about $5 million in revenue. Southern acquired the business, stepped in as CEO and Chairman, and ran it for a decade. By the time he exited, investor returns exceeded 24× the acquisition capital, a staggering outcome that validated the entire concept.

Southern’s success proved three things. First, a young MBA with no prior operating experience could acquire and meaningfully grow a small company. Second, the economics for investors were extraordinary. Third, the structure worked: the two-stage fundraise (search capital, then acquisition capital) kept risk manageable for both sides. After exiting Uniform Printing, Southern went on to co-found Pacific Lake Partners in 2009 with Coley Andrews, one of the first institutional vehicles dedicated exclusively to search fund investing. The firm has since backed hundreds of search fund entrepreneurs and invested in over 70 companies.

Growth in the first decade was glacial. Fewer than 20 search funds were raised between 1984 and the mid-1990s. The model was essentially an oral tradition passed among Stanford GSB alumni, a handful of professors, and their personal networks. There was no primer, no conference, no dataset. Each new searcher was largely reinventing the wheel.

Building the Evidence Base: The Stanford Search Fund Studies (1996-2024)

What transformed the search fund from a niche Stanford experiment into a legitimate asset class was data. Starting in 1996, the Center for Entrepreneurial Studies began systematically surveying every search fund it could identify, tracking fundraising, acquisitions, operating outcomes, and investor returns. The resulting biennial studies became the gold standard for search fund returns analysis.

Fourteen editions have been published to date, in 1996, 1998, 2001, 2003, 2005, 2007, 2009, 2011, 2013, 2016, 2018, 2020, 2022, and 2024. Each edition expanded the dataset and refined the methodology. Key milestones in the study series include:

• 2001 study: The first widely cited edition, documenting a 36% gross IRR, a number that caught the attention of institutional investors and business school faculty outside Stanford.
• 2018 study:Covered 401 search funds and reported a 35.3% gross IRR, representing the largest dataset at the time and cementing the model’s track record across multiple economic cycles.
• 2022 study:Updated data through December 31, 2021, showing 35.3% gross IRR and 5.2× return on invested capital. The study also tracked a record-setting year for new fund formations.
• 2024 study: The most recent edition covers 681 qualifying search funds in the U.S. and Canada through December 31, 2023. Headline figures: 35.1% aggregate pre-tax IRR and 4.5× return on invested capital. A record 94 new searches launched in 2023 alone, and 63% of those that completed their search successfully acquired a company.

The consistent finding across all 14 editions, gross IRRs in the 33-36% range, is what makes search funds remarkable. Few asset classes have maintained that level of performance over a 40-year window, which is why top search fund investors continue to allocate capital to the model.

From Cottage Industry to Asset Class (2000-2015)

The early 2000s marked a turning point. The 2001 Stanford study gave the model academic credibility. Harvard Business School started writing case studies on search funds, exposing a new generation of MBA students to the concept. Between 2000 and 2005, the number of search funds raised roughly doubled the combined total of the previous 16 years, according to a 2016 University of Chicago analysis of ETA’s evolution. By the model’s 30th anniversary in 2014, approximately 350 funds had been raised globally.

Three structural changes drove this acceleration:

1. Dedicated investor firms emerged. Rich Kelley, a Stanford MBA who had been investing in search funds since 1994, co-founded Search Fund Partners in 2004 with David Carver, one of the earliest institutional vehicles focused purely on search fund deals. Pacific Lake Partners followed in 2009. These firms professionalized the investor side, creating repeatable diligence processes and standardizing search fund term sheets.
2. The self-funded model gained traction. Not every aspiring acquirer could, or wanted to, raise a traditional search fund. By the late 2000s, entrepreneurs began self-funding their searches, using personal savings and SBA 7(a) loans to acquire businesses without giving up the equity that a traditional search fund structure requires.
3. Deal sizes grew.The median purchase price of search fund acquisitions climbed from the $3-$10 million range in the 1990s to above $10 million by 2010, reflecting both inflation and searchers’ increasing ambition.

By 2010, roughly 180 total search funds had been raised, and cumulative acquisitions were approaching $2.5 billion. The model was no longer a Stanford curiosity, it was an asset class with a documented track record and a growing ecosystem of specialized capital.

Going Global: IESE and International Expansion

While Stanford tracked domestic search funds, the model was quietly crossing borders. IESE Business School in Barcelona published its first international search fund study in 2005 and has since released seven editions, most recently in 2024. The IESE 2024 study tracks 320 international search funds across 40 countries on five continents, documenting 146 completed acquisitions, 85 in Europe, 54 in Latin America, 5 in Asia-Pacific, 1 in the Middle East, and 1 in Africa.

The countries with the most first-time fund launches tell the story of where the model has taken deepest root: Spain leads with 67, followed by Mexico (50), the United Kingdom (35), and Brazil (34). The median international acquisition has a purchase price of $11.7 million, $7.8 million in revenues, a 24% EBITDA margin, and about 50 employees.

Several factors fueled international adoption. European business schools, IESE, INSEAD, London Business School, began teaching the search fund model, creating local pipelines of aspiring searchers. Baby-boomer succession dynamics are not unique to the United States; Europe and Latin America face similar waves of retiring business owners with no succession plan. And a new record of 59 international search funds launched in 2023 alone, suggesting the global trajectory is still accelerating.

The Modern ETA Ecosystem (2015-Present)

Today’s entrepreneurship-through-acquisition market barely resembles the one Jim Southern entered in 1984. The traditional search fund remains the flagship model, 94 new ones launched in 2023, a record, but it now coexists with a constellation of related structures:

• Self-funded search: The fastest-growing variant. Searchers skip the initial fundraise, bear their own search costs, and raise acquisition capital only when they have a deal in hand. SBA 7(a) loans are the workhorse financing tool. Learn more in our traditional vs. self-funded comparison.
• Search fund accelerators: Programs like Search Fund Accelerator (founded 2015), Relay Investments, and Trilogy Search Partners provide structured cohort experiences, combining capital, mentorship, and operational training. Our guide to search fund accelerators covers the leading programs.
• Pledge funds: Investor groups that commit to evaluating each deal individually rather than pooling capital upfront. The pledge fund model gives investors more control while still supporting the searcher.
• Fundless sponsors and independent sponsors: Experienced operators who source deals without a committed fund, assembling capital on a deal-by-deal basis.

The investor base has matured alongside the models. Family offices, endowments, and dedicated search fund investment firms now maintain standing allocation pools. Search capital raised across the U.S. and Canada grew from $5 million in 2010 to $75 million in 2023, a 15× increase in just 13 years.

Demographics are shifting too. The 2024 Stanford study reports that 18% of new searchers in 2023 were women, and the vast majority of searchers are 35 or younger. Community infrastructure has exploded: SearchFunder.com, the Stanford Search Fund Conference, the IESE International Search Fund Conference in Barcelona, MIT’s ETA conference, and dedicated newsletters and podcasts now serve a global audience of aspiring acquirers.

Why the Model Has Endured for 40 Years

Many financial innovations flame out within a decade. Search funds have not only survived but accelerated. Several structural features explain the durability:

• Incentive alignment:The searcher’s 20-30% equity stake creates CEO-level motivation with a direct tie to investor returns. Both sides win or lose together.
• Structural market advantage:Search funds target the $1-$5 million EBITDA “sweet spot” where private equity competition is thin and sellers value a relationship-driven buyer who will preserve their legacy.
• Decades of data:Fourteen Stanford studies and seven IESE studies have refined the playbook from fundraise to exit, reducing the “reinventing the wheel” problem that plagued early searchers.
• Demographic tailwind: The baby-boomer retirement wave is creating a growing supply of quality acquisition targets, an estimated 10,000 U.S. small-business owners reach retirement age every day, and many lack a succession plan.
• Scalable talent pipeline: The model has expanded beyond Stanford to business schools worldwide, and the rise of self-funded search means you no longer need an elite MBA to participate. For a full assessment of whether the path suits you, see is ETA right for you.

Frequently Asked Questions

Who invented the search fund model?

H. Irving Grousbeck, a professor at Stanford Graduate School of Business, conceptualized the search fund in 1984. Grousbeck later co-founded Stanford’s Center for Entrepreneurial Studies in 1996 and is also known as a co-owner of the Boston Celtics (acquired in 2003). The first person to execute the model was Jim Southern (Stanford MBA ’83), who raised $150,000, acquired Uniform Printing, ran it for 10 years, and returned investors more than 24× their capital.

How many search funds have been raised since 1984?

The 2024 Stanford study counts 681 qualifying search funds in the United States and Canada. IESE’s 2024 international study adds 320 funds outside North America. Combined, over 1,000 search funds have been launched globally across 40+ countries since 1984.

What returns do search funds generate?

Across all 681 funds in the Stanford dataset, the aggregate pre-tax IRR is 35.1% and the return on invested capital is 4.5×. These figures have remained remarkably stable across 14 biennial studies, typically falling in the 33-36% IRR range. For a deeper analysis, read our guide to search fund returns.

Do I need a Stanford MBA to do a search fund?

No. While the model originated at Stanford, searchers now come from dozens of business schools and increasingly from non-MBA backgrounds. The self-funded search model in particular has opened the door to operators, industry veterans, and career-changers who bypass the traditional fundraise entirely. The 2024 Stanford study shows the searcher demographic is diversifying in both age and gender.

What is the difference between a traditional search fund and a self-funded search?

In a traditional search fund, the entrepreneur raises search-stage capital from a group of investors before beginning the search. Those investors get the right (but not the obligation) to invest in the eventual acquisition. In a self-funded search, the entrepreneur covers search costs personally and only raises capital when a specific deal is identified, typically using SBA loans, seller financing, or private investors. Our traditional vs. self-funded guide breaks down the tradeoffs in detail.
