The funnel is brutal. Stanford GSB's 2024 Search Fund Study documents what it takes to close one acquisition: 3,404 initial contacts produced 256 responses, 124 positive follow-ups, 25 in-person meetings, 4 LOIs, and one signed deal. The IESE 2024 International Search Fund Study, covering 320 funds across 40 countries, lands at the same number: the average operator contacts over 3,000 companies to close one acquisition.
That is not a bug in the model. It is the job description.
What separates the 63% of search fund operators who close from the 37% who do not is not valuation skill or diligence discipline. It is sourcing volume and channel discipline. You can be the best acquirer in the room and never close if your deal flow runs dry.
Here is where businesses worth buying actually come from, and how to build a system that produces them.
The four sourcing channels
Every acquisition comes through one of four doors: broker-listed marketplaces, regional M&A advisors, direct proprietary outreach, or your personal network. They are not created equal.
The Search Investment Group's 2023 Self-Funded Search Study (279 respondents, 109 completed acquisitions) mapped how self-funded operators actually sourced their deals: 54% from transaction intermediaries (brokers, investment bankers), 25% through proprietary outreach, 15% through personal network, and 6% through other intermediaries including attorneys and accountants.
Read that differently: 46% of completed acquisitions came from channels that had nothing to do with a listed marketplace.
Channel 1: Broker marketplaces
BizBuySell is the largest US marketplace, with roughly 100,000 active listings at any given moment. It skews Main Street: restaurants, retail, service businesses under $2M. There are 2,473 broker firms in the US, but concentration is extreme. Seventeen firms list half of all US small-business inventory. The median asking price across all listings is $396,000. Ninety-five percent of listings fall under the $5M SBA 7(a) ceiling.
The advantage is speed. You can screen dozens of deals in a week. The disadvantages are price and quality.
Listed deals consistently trade at a 0.5x to 1.0x SDE multiple premium over comparable off-market transactions. That premium exists because broker processes create competition and anchor seller price expectations. A seller who ran a formal process expects full value. You are rarely the only buyer.
Expect to screen 40 to 60 listings to find one worth a serious introductory call. Of those calls, approximately one in five produces a seller willing to share clean financials without a scripted broker pitch. Time from first contact to LOI on a broker listing typically runs 90 to 170 days.
BizBuySell is not where most operators find their best deal. It is where they get repetitions. Use it to understand what is selling, at what multiples, and how long listings sit before price cuts. That intelligence sharpens your negotiating position on every other channel.
Other marketplace options include Acquire.com for digital and SaaS-adjacent businesses, Empire Flippers for curated online businesses, and Flippa for micro-sites and digital assets.
Channel 2: Regional M&A advisors
This is the channel most operators underwork and where strong deal flow eventually comes from.
Boutique business brokers and regional M&A advisors handle deals before they hit any marketplace. They premarket businesses to qualified buyers, run a quiet sales process with the seller's trust already established, and move to public listing only if the quiet process fails.
The strategy is relationship development, not transaction hunting. You are not calling to ask what is available today. You are calling to establish yourself as a credible, pre-qualified, non-PE buyer who understands the lower middle market, can move on SBA financing, and will close.
Build a list of 15 to 20 regional advisors covering your target geographies and industries. Run a 90-day outreach campaign to get one real conversation with each. Then stay in contact monthly. Time from first meaningful advisor relationship to a deal worth signing typically runs 4 to 8 months.
Deal quality is higher. The seller is prepped. Financials are cleaner. You are competing with fewer buyers because the deal never hit a marketplace. The sell-side commission (typically 8 to 12% in the lower middle market) is still embedded in the price. But the absence of a competitive auction often compresses the acquisition multiple enough to offset that cost.
Channel 3: Direct proprietary outreach
Proprietary deals are the only channel that gives you pricing control. When you are the first and only buyer, there is no competitive auction to anchor the seller's expectations.
The IESE 2024 data is unambiguous: 64% of international search fund acquisitions came from proprietary sources. Stanford's Best Practices research recommends allocating 80% of search time to proprietary and industry-driven sourcing, with 20% to brokered deals.
Why the tilt? Axial's research shows that lower-middle-market companies sourced proprietarily trade at median acquisition multiples approximately 15% lower than comparable brokered deals. Top-quartile search fund operators paid a median 4.5x EBITDA. Bottom three quartiles paid 4.8x. The top quartile was buying larger, faster-growing, more profitable businesses at lower prices. That is the proprietary sourcing premium.
The work is harder and slower. A realistic solo pace is 50 to 80 personalized owner contacts per month across email, LinkedIn, and phone. At a 4 to 6% cold response rate, that is 2 to 5 real conversations per month. Over six months, that is 12 to 30 conversations with owners who are not listed anywhere. That is your pipeline.
Your target list profile: businesses with $500K to $3M in SDE, 10-plus years in operation, owner aged 55-plus, no obvious succession plan, and recurring revenue. Public databases including D&B Hoovers and state business registries provide the raw universe. Tools like Grata and Apollo offer contact data and sequencing infrastructure.
Personalized outreach outperforms generic templates by nearly 3x on response rate. Timeline-based subject hooks ("I noticed your business just passed its 20th year of operation") produce roughly 10% reply rates. Generic openers produce 4 to 5%. Your reputation in a tight industry network matters. Keep volume high and personalization real.
Per the SIG study, 68% of proprietary acquisitions started with cold email as the first contact. Cold calling was second.
Channel 4: Personal network
Fifteen percent of self-funded search acquisitions came through the operator's personal network. This channel is underrated because it is unscalable, but when it works, it works fast.
Former employers, industry contacts, attorneys, CPAs, and wealth advisors all know business owners thinking about exit. A message to 50 trusted contacts explaining what you are looking for costs an hour. It can surface a deal in a week.
Work your network before you build your outreach list. Start there. Then build the other three channels in parallel.
How to allocate across channels
The data suggests running all four channels simultaneously from day one, not sequentially.
Broker listings give you immediate repetitions: deal screening, CIM review, broker relationship building, and LOI practice. Your direct outreach pipeline compounds in the background toward higher-quality deals. Your advisor network develops over months and eventually surfaces deals no marketplace will show.
Self-funded searchers submitted an average of 6.9 LOIs, with only 2.4 executed, and fewer than 44% of executed LOIs resulted in a closed deal. That funnel math requires a wide, active top of funnel running continuously. Not a sequential "evaluate one deal at a time" approach.
The operators who close in 12 to 18 months started building all four channels on day one and never stopped.

The non-negotiable
Over 80% of businesses that eventually sell are never formally listed with a broker. That number is the whole thesis for doing proprietary outreach.
The businesses worth buying are rarely the ones that are easy to find. They are owned by people who never thought about selling until the right operator showed up at the right time with the right offer. Your job in the search phase is to be that operator, for enough businesses, often enough, that one of them says yes.
Three thousand contacts. One deal. Start the clock.
Frequently Asked Questions
How many businesses do search fund operators typically contact before closing an acquisition?
According to Stanford GSB's 2024 research and the IESE 2024 International Search Fund Study, the average search fund operator contacts over 3,000 companies to close a single acquisition. Stanford's documented best-practice example showed 3,404 initial contacts resulting in 256 responses, 25 meetings, 4 LOIs, and one closed deal.
What percentage of businesses for sale are listed with a broker?
Practitioner estimates suggest over 80% of businesses that eventually sell are never formally listed with a broker. The vast majority of the acquisition market is invisible to anyone relying solely on public marketplaces like BizBuySell or Acquire.com.
Do broker-listed deals or off-market deals produce better outcomes for acquisition operators?
Off-market and proprietary deals consistently produce better acquisition outcomes on price. Research from Axial shows proprietary deals trade at median acquisition multiples approximately 15% lower than brokered comparables. The IESE 2024 study found 64% of international search fund acquisitions came from proprietary sources, and Stanford's Best Practices recommends allocating 80% of search time to proprietary sourcing.
How long does the sourcing phase of a search fund typically take?
The median search duration for search fund operators is 20 months, per the IESE 2024 International Study. About one in five searchers takes longer than 30 months. Self-funded searchers using intermediary channels completed their search phase in 12 months or less slightly more often (55%) than those using proprietary outreach (44%).
