A search fund is a capital vehicle raised by one or two individuals — the "searchers" — for the purpose of finding, acquiring, and operating a single private company. The searcher raises a small amount of initial capital (the "search capital") from investors to fund the search process — their salary, deal sourcing expenses, and due diligence costs. When the searcher identifies a suitable acquisition target, they raise acquisition capital from those same investors (and sometimes new ones) to complete the purchase. After close, the searcher becomes the CEO of the acquired company and operates it, typically for 4–8 years before engineering a sale. The search fund model is one expression of the broader concept of Entrepreneurship Through Acquisition (ETA) — buying a business to run, rather than starting one from scratch.
The Two Models: Traditional Search Fund vs. Self-Funded Search
The search fund landscape has bifurcated over the past decade into two distinct models, each with different economics, timelines, and investor structures.
The Traditional Search Fund
The traditional model was pioneered at Stanford Graduate School of Business in the 1980s and is well-documented in the Stanford Search Fund Primer. The structure:
1. The searcher raises $400,000–$600,000 in search capital from 10–20 investors (typically individuals with ETA experience, family offices, and search fund-focused funds). This capital covers approximately 18–24 months of full-time search. 2. Each investor receives a pro-rata right to invest their proportional share in the acquisition (when one is found), at the same valuation. 3. The searcher receives a salary during the search period (usually $75,000–$110,000 per year) and a carried interest stake in the operating company — typically 20–30% of equity, vesting over the post-acquisition operating period. 4. When a target is identified, the searcher returns to the investor group to raise the acquisition capital — typically $2M–$6M in equity, with the remainder financed through SBA or conventional debt. 5. Post-close, the searcher operates the company as CEO. Investors hold majority ownership; the searcher owns the carried interest stake, which vests through tenure and performance.
The Self-Funded Search
The self-funded model (also called a "bootstrapped search") eliminates the investor capital raise. The searcher funds their own search from personal savings, part-time work, or consulting income — then secures acquisition financing independently when a target is identified.
- No investors, no carried interest obligation, no investor approval required on deal selection - The searcher retains majority ownership of the acquired business (limited only by what the acquisition financing requires) - No search capital to fall back on — the searcher bears full economic risk during the search period - Typically funds acquisitions with SBA 7(a) debt, seller financing, and personal equity injection — the same stack available to any individual buyer - Common with searchers who have domain expertise in a specific industry and can conduct a focused search efficiently without a 24-month runway
Which model is right for whom?
| Factor | Traditional Search Fund | Self-Funded Search |
|---|---|---|
| Searcher capital required | Low (salary covered) | High (self-funded during search) |
| Acquisition capital availability | Higher (institutional investor network) | Limited to debt + personal equity |
| Typical acquisition size | $3M–$20M enterprise value | $500K–$5M enterprise value |
| Equity ownership at close | 20–30% (carried interest) | 80–100% |
| Investor oversight | Significant (board, investor approval on deal) | None |
| Timeline | 18–30 months (search + close) | 6–24 months |
| Best for | MBA graduates, first-time operators targeting larger businesses | Experienced operators, industry-specific searchers |

ETA — Entrepreneurship Through Acquisition — is the broader term for the strategy of becoming a business owner by buying an existing operating business rather than starting one from scratch.
The ETA thesis is straightforward: a starting business has zero customers, zero revenue, zero proven processes, and a high failure rate. An existing business with $500,000 in SDE, an established customer base, a trained staff, and a decade of operational history has de-risked the hardest parts of entrepreneurship. The buyer acquires the outcome of the founder's 10–20 years of work — paying for it, but not having to recreate it.
Why ETA has grown in prominence:
The baby boomer demographic transition has created an unprecedented supply of established small businesses whose founders are ready to exit. Estimates suggest that 4–5 million small businesses will change hands over the next decade as the generation that built them in the 1980s and 90s moves toward retirement. Many of these businesses have strong cash flows, loyal customer bases, and limited competition from private equity (which requires larger transaction sizes) — creating an acquisition opportunity for individual buyers.
At the same time, MBA programs (Stanford, Harvard, Booth, Wharton, and dozens of others) have formalized ETA education, creating a pipeline of trained buyers who understand the search fund model and have access to investor communities.
ETA vs. starting a business — the risk profile:
| Factor | ETA (Acquisition) | Startup |
|---|---|---|
| Time to first dollar of revenue | Day 1 (existing revenue) | Months to years |
| Risk of total failure | Lower (proven concept) | Higher |
| Required capital | Higher (purchase price) | Lower (startup costs) |
| First 90 days | Operational transition | Product development |
| Potential upside | Moderate to high | Very high (but low probability) |
For most buyers who prioritize cash flow over lottery-ticket upside, ETA produces better risk-adjusted outcomes than starting from scratch. For context on how acquisitions are structured and what deal mechanics look like in practice, see the mergers and acquisitions beginner's guide.
What Search Funds Target: The Ideal Acquisition Profile
Search funds — both traditional and self-funded — target a specific type of business. The profile that the ETA community has converged on over decades of data reflects what produces the best post-acquisition outcomes.
The canonical search fund acquisition target:
- Revenue: $1M–$20M (traditional search funds target $5M–$20M; self-funded searchers often target $1M–$5M) - EBITDA or SDE: $500K–$3M+ — enough to service acquisition debt and pay a CEO salary - Business type: Business-to-business services, niche manufacturing, essential services, specialized distribution - Market position: Established niche leader with defensible position — not #1 in a huge market, but often #1 or #2 in a defined geography or specialized vertical - Revenue type: Recurring or repeat — contracts, service agreements, subscription models, or businesses where the same customers return regularly without extensive new business development - Owner situation: Founder-owned, owner ready to exit, no succession plan — the classic "baby boomer retirement" scenario - Complexity: Operationally straightforward enough for a generalist CEO to run; limited by regulatory compliance requirements or specialized technical expertise that cannot be transferred
What search funds avoid: - Businesses entirely dependent on the seller's personal relationships or licenses - Consumer-facing retail with lease risk and trend sensitivity - Businesses in declining industries with structural tailwinds working against them - Businesses where the primary customer is a single large buyer (customer concentration) - Turnarounds — businesses where the operating problem, not the deal structure, is the primary challenge
Why service businesses dominate ETA acquisitions: The small business landscape is dominated by service companies — cleaning, HVAC, landscaping, IT services, healthcare services, staffing. These businesses have low capital expenditure requirements, recurring customer relationships, and operating models that a new owner can learn within 90–180 days. For how service businesses are valued and what specific factors affect their acquisition price, see how to value a service-based business.
The Search Process: How Searchers Find Deals
The search process — finding the right business to acquire — is what distinguishes successful ETA buyers from those who spend 2 years searching without a close. Most searches are either too broad (trying to acquire "anything good") or too passive (relying entirely on broker listings).
The three channels for deal sourcing in a search:
1. Business broker and M&A advisor listings. Brokers represent sellers and present listed deals to qualified buyers. For self-funded searchers targeting businesses under $3M enterprise value, broker-listed deals on platforms like BizBuySell, BizQuest, and DealFlow OS are a significant source. For traditional searchers targeting larger businesses, investment bankers running formal sale processes are the primary channel.
2. Proprietary outreach (direct to sellers). Many of the best search fund acquisitions come from direct outreach to business owners who have not yet engaged a broker — cold letters, phone calls, and introductions through industry networks. Proprietary outreach targets specific industries and geographies, builds a relationship with the seller before they list, and allows the searcher to negotiate without a competitive process. This requires time and volume — a systematic outreach to 300–500 business owners to generate 10–20 substantive conversations.
3. Referral networks. Advisors (CPAs, attorneys, financial planners) who serve business owners are often the first to know when an owner is considering selling. Building relationships with the professional advisor community in a target geography or industry is one of the most effective proprietary deal generation strategies.
Typical search economics (traditional model): - 300–500 companies contacted - 50–100 introductory conversations - 15–25 meetings with serious sellers - 5–10 NDAs signed and CIMs reviewed - 2–4 LOIs submitted - 1 deal closed
Most searches close their acquisition within 18–30 months of starting. Searchers who close faster are typically those with a defined industry focus, a systematic outreach process, and investor networks that can move quickly at the LOI stage.
The Economics of a Traditional Search Fund
Understanding the financial structure of a traditional search fund helps both searchers and investors evaluate whether the model fits their goals.
Search capital economics: - Typical raise: $400,000–$600,000 from 10–20 investors - Investor ownership at the search stage: Each investor receives "units" that convert to equity in the acquisition company - Searcher compensation: $75,000–$110,000/year salary during the search period, plus benefits - Timeline: 18–24 months on average; investors fund the full search period
Acquisition capital economics (at close): - Total enterprise value of target: typically $3M–$15M in traditional search funds - Capital stack: 50–70% debt (SBA 7(a) or conventional), 30–50% equity raised from investors - Searcher equity: Carried interest of 20–30% of equity, typically vesting over 4–5 years post-close - Investor equity: 70–80% of the operating company (after accounting for carried interest)
What the financial outcome looks like:
A traditional search fund acquires a business for $8M (5x $1.6M EBITDA). Equity structure: $3.2M from investors (40%), $4.8M SBA/conventional debt (60%). The business grows EBITDA to $2.5M over 6 years and exits at 6.5x EBITDA = $16.25M enterprise value, less remaining debt of $2.5M = $13.75M equity value.
Searcher carries 25% = $3.44M to the searcher. Investors' 75% = $10.31M on $3.2M invested = 3.2x multiple on invested capital.
This is the theoretical structure. Outcomes vary dramatically based on the quality of the acquisition and the operator's execution. The Stanford search fund data (updated annually) shows that the median search fund has produced strong returns for investors, with the upside driven by the top quartile of performers.
Frequently Asked Questions
What is a search fund?
A search fund is a capital vehicle raised by one or two individuals to fund the process of finding, acquiring, and operating a single private business. The searcher raises initial "search capital" (typically $400K–$600K) to cover a 18–24 month search period, then raises additional "acquisition capital" from investors to close the deal. After closing, the searcher becomes the CEO of the acquired company. The model is a form of Entrepreneurship Through Acquisition (ETA) — becoming a business owner through purchase rather than by starting from scratch.
What is the difference between a traditional search fund and a self-funded search?
A traditional search fund raises external investor capital for both the search period (salary + expenses) and the acquisition. Investors receive equity in the acquired business; the searcher receives a carried interest stake (20–30%). A self-funded search has no external investors — the searcher funds their own search from savings or income, then finances the acquisition through SBA loans, seller financing, and personal equity. Self-funded searchers retain full ownership but take on more personal financial risk during the search period.
What is ETA (Entrepreneurship Through Acquisition)?
Entrepreneurship Through Acquisition (ETA) is the strategy of becoming a business owner by buying an existing operating business rather than building one from scratch. ETA buyers acquire established companies with proven revenue, existing customers, and trained staff — bypassing the startup phase. The search fund model is one form of ETA; individual buyers using SBA financing are another. ETA has grown significantly as retiring baby boomers have created a large supply of profitable small businesses without natural successors.
What types of businesses do search funds acquire?
Search funds typically target business-to-business (B2B) service companies, niche manufacturers, essential service providers, and specialized distributors with $500K–$3M+ in EBITDA or SDE. They prefer businesses with recurring or repeat revenue, established market positions in defensible niches, and owner-retirement exit motivations. They typically avoid consumer retail, highly regulated industries requiring specialized licenses, turnarounds, and businesses with extreme customer concentration.
How long does a search fund search take?
The typical traditional search fund closes an acquisition within 18–30 months of starting the search. Self-funded searches often run 6–24 months depending on the searcher's deal volume and industry focus. Searches with a defined industry focus and a systematic proprietary outreach process close faster than those with broad or unfocused sourcing strategies. Most searchers contact 300–500 businesses, hold 50–100 conversations, and submit 2–4 LOIs before closing one deal.
The search fund and ETA model represents one of the most well-documented paths to business ownership for individuals who want to lead an established company rather than build one. The traditional model provides institutional support, investor networks, and deal capital — at the cost of shared equity. The self-funded model preserves ownership — at the cost of personal financial exposure during the search. Both are viable paths to the same outcome: owning and operating a profitable small business. For the acquisition mechanics that every ETA buyer needs to understand before signing an LOI — deal structure, asset vs. stock purchase, buyer types, and the M&A process — see the [mergers and acquisitions beginner's guide](/blog/mergers-and-acquisitions-beginners-guide).
