Entrepreneurship through acquisition is an education and career category for buying an existing company to run, not a financing structure; the structure is chosen separately and decides who owns the company at the end.
What does entrepreneurship through acquisition mean?
Entrepreneurship through acquisition, usually shortened to ETA, is the umbrella term for becoming an owner-operator by buying an existing company rather than founding one. It is an education and career category, not a financing structure. Chicago Booth's Polsky Center describes its ETA programs as giving students and alumni access to the education, capital, mentorship, and resources needed to acquire and grow small businesses, and its annual ETA conference draws more than 900 attendees. Several other business schools run similar programs and conferences.
The word matters because it is used loosely. A person who says they are "doing ETA" may be raising a traditional search fund, searching on their own savings, joining an accelerator, or acting as an independent sponsor. Each of those is a different financing structure with a different owner at the end of it, and the search fund versus self-funded search guide is the comparison. This page is the map of the whole category.
What are the paths under the umbrella?
Five, in rough order of how much outside capital funds the search itself:
- Traditional search fund. Ten to fifteen investors fund a two-year search through units of $35,000 to $50,000, then fund the acquisition. The searcher earns up to 25 percent of the common equity alone, or 30 percent as a pair, in three tranches, behind the investors' participating preferred. Stanford's biennial study counts only this model.
- Self-funded search. The searcher pays for the search, takes no salary, and finances the company with an SBA 7(a) loan, their own cash as the equity injection, and often a seller note on standby. The searcher keeps most of the equity. Stanford excludes this model from its data and calls it the most numerous of the models it leaves out.
- Sponsored or accelerator search. A single sponsor or an accelerator fund pays for the search, provides coaching, and sets the searcher's equity terms. No published outcome data of Stanford's quality exists for it.
- Independent sponsor. A dealmaker who finds a company, signs a letter of intent, and then raises the equity from investors deal by deal, earning a closing fee, a management fee, and a share of profits above a hurdle rather than an operating role or a guaranty.
- Long duration enterprise. A committed pool of capital raised to buy and hold for 10 to 20 years, with incentives built for that horizon. Stanford tracks these separately.
Which path does the Stanford data describe?
The first one only. The 2024 study states that it excludes funds led by principals who had previously raised a search fund, self-funded their search, or pursued their search with a single search investor. Every figure that circulates about search fund returns, from the 33.9 percent aggregate investor return through the 58 percent acquisition rate and the 19 month median search, describes investor-funded first-time searchers buying companies with a median purchase price of $14.4 million in the 2024 study and $16 million for 2024 and 2025 closings.
That is not the self-funded universe. In fiscal 2025 the average SBA 7(a) change-of-ownership approval was about $1.16 million, computed from the agency's own data in the lending report. The two paths are an order of magnitude apart in company size, which is why quoting one path's data for the other misleads.
What do the ETA programs actually provide?
Three things, at the schools that run them. Courses on searching, valuing, financing, and operating an acquired company. Access to the investors who fund traditional search funds, who recruit at those programs. And a community of searchers at the same stage, which is worth more than it sounds during a two-year search that most people run alone.
What they do not provide is a financing structure. A student who leaves an ETA program still has to choose between raising a fund and searching on their own capital, and the choice is made by the size of company they want and the equity they want to keep, not by the program.
How does a self-funded searcher fit under the umbrella?
As the path that owns the most and is measured the least. The self-funded cap table is set by three documents: the statute caps a 7(a) loan at $5 million gross, 13 CFR 120.160 requires a personal guaranty from every owner of 20 percent or more, and SOP 50 10 version 8 requires a 10 percent injection on a complete change of ownership with a full-standby seller note allowed to supply up to half of it. SBA lists version 8 as effective June 1, 2025 and version 8.1 as effective October 1, 2026, and the rules can move at that boundary.
The mechanic that makes small outside equity possible on this path is that in a complete change of ownership an investor below 20 percent does not have to guarantee the loan. In a partial change of ownership every owner does, for a period. A self-funded searcher planning to bring in family or a few small investors chooses the structure before recruiting them.
What should a person considering ETA do first?
Decide the size of company, because that decides the path. A company that needs more than $5 million of senior debt is a traditional fund or a sponsor, and the searcher will own a minority of it. A company under that line is a self-funded purchase, and the searcher will own most of it and guarantee the debt. Then read the financing guide for the structure, the buying guide for the process, and, for the self-funded path, the free course, which is that process in six lessons.
Questions people ask next
Is ETA the same as a search fund?
No. A search fund is one path under the ETA umbrella, the investor-funded one. Self-funded search, sponsored search, independent sponsorship, and long duration enterprises are the others, and each ends with a different owner.
Do I need an ETA program to buy a business?
No. The programs teach the process and connect students to the investors who fund traditional search funds. A self-funded searcher needs neither, and a lender underwriting the purchase does not ask.
Which path lets me own most of the company?
The self-funded search, financed with an SBA 7(a) loan. The searcher supplies the equity injection, signs the guaranty, and keeps most of the equity. A traditional fund leaves the searcher up to 25 to 30 percent of the common, earned in tranches.
Why does Stanford exclude self-funded searches?
Its study defines a search fund as investor-funded from the search onward and counts only first-time, investor-backed searchers. Self-funded searches do not fit the definition, and the study says so on its own page 4.
