The Stanford Search Fund Primer is the foundational document of the Entrepreneurship Through Acquisition (ETA) movement. Originally published by the Stanford Graduate School of Business, it has guided thousands of aspiring entrepreneurs toward acquiring and operating existing businesses rather than starting from scratch.
This guide summarizes the key concepts from the Stanford Search Fund Primer, explains how the search fund model works, and shows how it connects to modern business acquisition financing — including SBA 7(a) loans, which have become the dominant funding mechanism for Main Street acquisitions.
What Is a Search Fund?
A search fund is an investment vehicle through which an aspiring entrepreneur (the “searcher”) raises capital from investors to fund a full-time search for a privately held company to acquire, manage, and grow. The concept was pioneered at Stanford GSB in 1984 by Professor H. Irving Grousbeck, and the Stanford Search Fund Primer has been updated regularly since then.
The search fund model follows a distinct lifecycle:
- Raise Search Capital: The searcher raises $400K–$750K from investors to fund 18–24 months of full-time searching
- Search for a Target: The searcher evaluates hundreds of companies to find one worth acquiring
- Acquire the Company: Once a target is identified, the searcher raises acquisition capital from the same investors (and potentially others)
- Operate and Grow: The searcher becomes CEO and runs the company for 5–10 years
- Exit: The company is sold, generating returns for investors and the searcher
Key Findings from the Stanford Search Fund Study
Stanford has published multiple studies tracking search fund returns over decades. The key findings include:
Return Profile
- Aggregate pre-tax return: 32.6% IRR across all search funds studied (per the 2022 study)
- Return on invested capital (ROIC): 5.4x aggregate multiple
- Median acquisition size: $8.8 million in enterprise value
- Average acquisition revenue: $11.4 million
- Average EBITDA at acquisition: $2.1 million
Success Rates
- Approximately 75% of searchers successfully acquire a company
- Of those who acquire, roughly 70% generate positive returns for investors
- The top quartile of search funds generate outsized returns, significantly pulling up the aggregate
- Search fund returns have consistently outperformed the S&P 500 and most PE benchmarks
What Makes Search Funds Succeed
- Industry selection matters: B2B services, healthcare services, and technology-enabled services produce the best outcomes
- Recurring revenue is king: Companies with subscription or contract-based revenue consistently outperform
- Prior operating experience helps: Searchers with industry-relevant experience acquire better companies
- Growth orientation: The most successful search fund CEOs focus on top-line growth, not just cost-cutting
- Deal sourcing breadth: Successful searchers evaluate 100+ companies and develop relationships with business brokers and intermediaries
The Traditional Search Fund Model vs. Modern Alternatives
The Stanford model describes the traditional search fund — institutionally backed, typically post-MBA. But the ETA landscape has evolved dramatically since 1984:
| Feature | Traditional Search Fund | Self-Funded Search | SBA-Financed Acquisition |
|---|---|---|---|
| Capital Source | Institutional investors | Personal savings | SBA 7(a) loan + 10% equity |
| Typical Deal Size | $5M–$30M | $500K–$5M | $500K–$5M |
| Equity Dilution | Searcher keeps 25–30% | Searcher keeps 100% | Searcher keeps 100% |
| Down Payment | Raised from investors | 100% personal | 10% (or 5% with seller note) |
| Search Salary | $100K–$150K/year | None (self-funded) | None (part-time OK) |
| Investor Oversight | Board seats, reporting | None | None |
| Best For | MBA grads, larger deals | Experienced operators | First-time buyers, Main Street |
How SBA Loans Changed the Search Fund Game
The Stanford Search Fund Primer focuses on the traditional institutional model. But the reality in 2026 is that most small business acquisitions — the kind the Primer describes as ideal targets — are financed with SBA 7(a) loans, not institutional search fund capital.
Here’s why SBA loans have become the dominant acquisition financing vehicle for deals under $5 million:
- You keep 100% ownership. Traditional search funds require giving up 70–75% of equity to investors. With an SBA loan, you own the entire company.
- Only 10% down. SBA 7(a) loans cover up to 90% of the acquisition cost. With a full standby seller note, you may need as little as 5% down.
- No investor oversight. You’re the CEO and the sole owner. No board meetings, no reporting requirements, no investors to answer to.
- Government guarantee makes approval easier. The SBA guarantees 75–85% of the loan, making banks more willing to lend for acquisitions.
- Rates are capped by law. SBA loan rates are tied to Prime + a fixed spread, currently 6.75%–13.25% depending on loan size.
In CY2025, SBA 7(a) lenders funded over $36 billion in loans, with business acquisitions representing a major and growing category. The top 50 SBA lenders for acquisitions funded nearly $5 billion in acquisition financing alone.
The Stanford Search Fund Target: What Makes an Ideal Acquisition
The Stanford Primer describes the ideal acquisition target. These criteria align almost perfectly with what SBA lenders look for:
- Steady, predictable cash flows — SBA lenders want to see consistent revenue and EBITDA
- Established business (5+ years) — SBA prefers businesses with operating history
- Low customer concentration — no single customer represents more than 20% of revenue
- Recurring or repeat revenue — subscription, contract, or habitual purchase patterns
- Fragmented industry — room for growth through operational improvements or acquisitions
- Owner-dependent businesses welcome — if the buyer can replace the owner’s role (SBA lenders evaluate this via management transition plans)
- $1M–$5M EBITDA sweet spot — large enough to service debt, small enough to be acquisition-appropriate
The Search Process: How to Find Your Acquisition Target
The Stanford Primer emphasizes a systematic search process. Whether you’re running a traditional search fund or self-funding your search, the process is similar:
1. Define Your Criteria
Industry focus, geographic preference, deal size range, minimum EBITDA, and management transition requirements. The tighter your criteria, the more efficient your search.
2. Source Deals
Business broker listings (BizBuySell, BizQuest), direct outreach to business owners, industry conferences, intermediaries, and your personal network. The Primer recommends evaluating 100+ companies to find one worth acquiring.
3. Evaluate and Screen
Financial analysis, competitive positioning, customer concentration, growth opportunities, and management transition feasibility. Most businesses you evaluate won’t meet your criteria — that’s normal.
4. Submit an LOI
Once you find a target, submit a Letter of Intent with your proposed terms, valuation, and deal structure. The LOI typically includes an exclusivity period for due diligence.
5. Due Diligence
Quality of Earnings (QoE) analysis, legal review, customer interviews, employee assessment, and operational deep dive. This is where deals live or die.
6. Secure Financing and Close
For SBA-financed acquisitions, this means working with an SBA loan broker to match your deal with the right lender, preparing your business plan and financial projections, and navigating the SBA approval process.
Search Fund Economics: The Math That Matters
Let’s compare the economics of a $2M acquisition under different models:
| Metric | Traditional Search Fund | SBA 7(a) Loan |
|---|---|---|
| Acquisition Price | $2,000,000 | $2,000,000 |
| Your Equity Required | $0 (investors fund it) | $200,000 (10%) |
| Your Ownership % | 25–30% | 100% |
| Value of Your Stake | $500K–$600K | $2,000,000 |
| Monthly Debt Payment | Varies by structure | ~$20,800/mo (10yr, 9.75%) |
| Annual Salary as CEO | Market rate (board approved) | Whatever you want |
| Exit at 2x (sell for $4M) | You get $1M–$1.2M | You get ~$4M (minus remaining debt) |
The takeaway: For deals under $5M, SBA financing lets you keep 100% ownership with just 10% down. The traditional search fund model makes more sense for larger deals ($10M+) where SBA limits don’t apply.
How the ETA Landscape Has Evolved Since the Primer
The Stanford Search Fund Primer laid the groundwork, but the business acquisition landscape in 2026 looks very different from 1984:
- The “boring business” movement: Popularized by Codie Sanchez (Contrarian Thinking) and others, everyday entrepreneurs are now buying laundromats, HVAC companies, and service businesses — not just MBA grads buying software companies
- SBA loans democratized access: You no longer need institutional investors or an MBA to acquire a business. SBA 7(a) loans have made acquisition financing accessible to anyone with 10% equity and relevant experience
- Online communities replaced campus networks: Programs like Acquisition Ace and Contrarian Thinking provide the education and community that was once only available at Stanford and HBS
- Deal flow is more transparent: Online marketplaces, broker networks, and data tools have made finding acquisition targets easier than ever
- The baby boomer retirement wave: 10,000+ business owners retire daily. The supply of businesses for sale has never been larger.

Frequently Asked Questions
What is the Stanford Search Fund Primer?
The Stanford Search Fund Primer is a research document published by Stanford Graduate School of Business that explains the search fund model of entrepreneurship through acquisition. First published in 1984, it has been updated multiple times and is considered the foundational text of the ETA movement.
What is the average return of a search fund?
According to Stanford’s research, the aggregate pre-tax IRR across all search funds is approximately 32.6%, with a 5.4x return on invested capital. However, returns are highly skewed — the top quartile generates outsized returns while some search funds result in total loss.
Do I need an MBA to do a search fund?
Not anymore. While the traditional search fund model was designed for MBA graduates, the modern ETA landscape includes self-funded searches, SBA-financed acquisitions, and community-based programs that don’t require an MBA. Relevant business experience and strong analytical skills matter more than credentials.
How is an SBA loan different from search fund financing?
An SBA 7(a) loan is debt financing — you borrow money from a bank (guaranteed by the SBA), put 10% down, and own 100% of the business. Search fund financing is equity — investors provide capital and receive 70–75% ownership. SBA loans are better for deals under $5M where you want full ownership. Search funds are designed for larger deals ($5M–$30M+) where the searcher lacks personal capital.
What size business should I target?
For SBA-financed acquisitions, the sweet spot is $500K–$5M in enterprise value with $200K–$1.5M in annual EBITDA. The SBA 7(a) loan maximum is $5M, though pari passu structures with multiple lenders can go higher. The business should have at least 3 years of operating history and consistent cash flows.
How do I finance a business acquisition?
The most common method for deals under $5M is an SBA 7(a) loan, which covers up to 90% of the purchase price. You provide 10% equity (or as little as 5% with a full standby seller note). Contact GoSBA Loans to explore your financing options — our service is 100% free for borrowers.
