What deal sourcing is, the UK deal sourcing platforms and services compared, and how to find businesses to acquire. Search fund operators contact 3,000+ companies to make one acquisition, and 37% never close: we break down the funnel with Stanford and IESE data.
Set your sector, region and EBITDA range, owner age included, and see which UK companies fit. The free trial includes 3 unlocks to reveal the companies behind the matches.
Build your buy boxThe search fund model has generated 35% aggregate IRR and 4.5x returns over four decades. A record 153 new funds launched globally in 2023. The asset class is proven, growing, and increasingly institutional.
And yet the most basic operational problem in the model, finding a business to buy, remains almost comically inefficient.
Stanford GSB's 2024 study and the IESE 2024 International Search Fund Study both converge on the same figure: the average search fund operator contacts over 3,000 companies to close a single acquisition. The median search takes 20 months. And 37% of funded searchers never acquire anything at all. They return whatever remains of their investors' capital after two years of salary, travel, and broken deals.
The discovery infrastructure that supports a $10 billion cumulative asset class is, in most cases, a spreadsheet, a LinkedIn subscription, and persistence.
We built ExitRadar to solve the UK version of this problem. Below we define deal sourcing, compare the UK platforms and services, set out how to find businesses to acquire, then show exactly why the search process is so broken, because the data is more damning than most searchers realise.
Deal sourcing is the work of finding businesses to buy. It has two halves: building the list of companies that fit what you want to acquire, and turning names on that list into conversations with their owners (often called origination).
There are two routes to a deal. On-market deals come through brokers, advisers and listing sites, where a business is already advertised and other buyers are looking at it too. Off-market (or proprietary) deals come from approaching owners directly, before any sale process exists, so there is usually no competing bidder.
Search funds, private equity buy-and-build platforms, trade acquirers and family offices all run the same process. We use search funds as the worked example here because theirs is the best-documented sourcing funnel in private markets.
Deal sourcing software, sometimes sold as deal origination software, falls into four working layers (listings, targeting data, outreach, and pipeline), plus a small group of all-in-one ETA platforms trying to combine them and outsourced deal sourcing companies that do the work for you. No single tool covers the whole job, and the layers are not interchangeable.
Listings (on-market). BusinessesForSale.com (a large general marketplace with a UK site), Daltons Business, RightBiz, and the more search-fund-oriented SME Market advertise businesses already for sale. They're free to browse and useful for market research, but every target is on-market and therefore competed over, and the best businesses often sell quietly before they'd ever appear. A supplementary channel, not a primary engine.
Targeting data (off-market). This is where proprietary sourcing is won or lost. Generic UK company-data platforms such as Beauhurst (high-growth private-company intelligence), Endole (Companies House prospecting and list-building), FAME/Orbis (enterprise financials and ownership, from Moody's Bureau van Dijk) and Company Watch (financial-health scoring via its H-Score) expose company attributes and let you filter. They're capable, but they hand you attributes and leave you to infer who might sell; none treats owner exit or succession readiness as a native output. US platforms like Grata, SourceScrub and Cyndx are powerful private-company discovery engines but built for US private-equity economics and enterprise budgets, with limited UK-SME granularity.
AI deal sourcing platforms. A newer group uses machine learning to read company websites and build target lists from a written description of what you want to buy. Grata markets its search this way, and Inven, a Helsinki-based platform founded in 2022, sells AI-built target lists mainly to private equity firms and investment banks. They find companies by what they do, which keyword filters miss, but they are global tools and say little about whether a UK owner is ready to sell.
Exit-readiness scoring (pre-market). This is the category ExitRadar occupies, and the response to the gap above. Rather than exposing raw filters, ExitRadar scores the full universe of 3.7 million active UK companies from Companies House data for exit and succession readiness, synthesising director age, tenure, single-director structure, filing behaviour, and financial health, then flags its highest-conviction tier, PURSUE: a strong business meeting strong exit signals. The distinctive element is the scored, ranked output, not the underlying data source: plenty of tools read Companies House, but turning that universe into a ranked list of businesses worth pursuing before any listing exists is what compresses the 3,000-company funnel. The timing score comes from a gradient-boosted machine-learning model trained on completed owner-to-owner business sales, described in our methodology. 21,385 UK companies are currently PURSUE-grade.
Outreach. Apollo.io (contact database plus sequencing), Instantly.ai (high-volume cold-email deliverability), and Lemlist (personalised multichannel outreach) execute the approach. They send messages but don't tell you whom to message. They sit downstream of a targeting layer.
Pipeline / CRM. HubSpot, Airtable, and ClickUp are the generic, flexible options most searchers configure into a deal tracker: cheap and familiar, but with no owner-signal data or ETA workflow.
All-in-one ETA platforms. BizCrunch (UK) combines filterable company data, built-in email and letter outreach, and deal tracking in one product. AlphaY.io is a purpose-built search-fund operating system (pipeline, contact management, financial analysis, and due diligence), though it brings no proprietary UK data of its own. ETA IQ is an earlier-stage search-fund CRM and deal-flow tracker. These are workflow-first: AlphaY and ETA IQ bring the process but no native data, while BizCrunch brings UK data and outreach but as a filter-and-enrich database rather than a predictive exit-readiness score. A targeting layer like ExitRadar sits naturally upstream of any of them.
Outsourced deal sourcing companies. Some buyers pay a firm to run origination for them. Captarget, a US firm, runs email, phone and broker-coverage campaigns for private equity and corporate buyers, often for add-on acquisitions, on a monthly retainer with no success fee. Danish Lead Co runs managed outbound origination for private equity buyers. These sell the work, not the data: you pay for conversations with owners, and the result is only as good as the brief and the target list behind it.

The targeting layer is the one worth being most deliberate about, because it determines the quality of everything downstream. Outreach and CRM tools are largely interchangeable; the difference between a search that closes and one that stalls is almost always the quality of the target list, not the software that emails it.
Free options. The listing sites are free to browse, and Companies House itself is free: every UK company's filings, officers and owners, with no scoring on top. HubSpot, Airtable and ClickUp all have free plans that work as a basic deal tracker. ExitRadar's trial includes three free reports.
Whatever tools you use, the work runs in the same order.

Stanford's Best Practices research documented a representative first-year outreach campaign by a single searcher: 3,404 initial contacts produced 256 responses, 124 positive follow-ups, 25 in-person meetings, 16 pricing conversations, and 4 LOIs submitted. One deal closed.
The IESE 2024 International Study, covering 320 funds across 40 countries, corroborates this almost exactly. The average international searcher explored over 3,000 businesses, held 159 personal conversations with owners, signed approximately 4 LOIs, and closed 1 deal.
The conversion rates at each stage are consistent across both studies:
Companies contacted: 3,000+. Responses received: 200–256, roughly 7–8%. Positive follow-ups from interested sellers: around 124, or 3.6%. In-person meetings: 25–50, under 1.5%. Pricing conversations: approximately 16, or 0.5%. LOIs submitted: 4–10, between 0.1% and 0.3%. Deals closed: 1, approximately 0.03%.
The average searcher signs 3.6 LOIs before closing, with the first LOI typically arriving at month 7.8 of the search. The median search duration is 20 months, up from a COVID-era low of 17 months in 2020–2021. Nearly a third of searchers take 20–30 months. One in five exceeds 30 months.
LOIs fail for identifiable reasons: 63% due to issues discovered during diligence, 48% over valuation disagreements, 38% from seller retraction, and 32% from competitive bidding. A critical leading indicator: 40% of searchers who haven't signed an LOI by month 12 never acquire a business.
A typical funded search raises $400k–$670k for a two-year search phase, with the median at $500k for US funds and approximately €450k–€650k for European funds. This capital comes from 10–20 investors contributing roughly $25k–$35k per unit.
For who writes those cheques here, see the most active UK search fund investors.
The budget breaks down roughly as follows: salary absorbs around 50%, or $120k–$150k per year. Travel and conferences consume about 10%. Legal fees take another 5%. CRM, software, interns, and research account for approximately 13%, or $40k–$80k over the full search. And diligence costs (primarily quality-of-earnings reports at $20k–$30k each) consume about 17%, or $100k total.
The pure software and tools budget typically falls between $5k and $30k per year. A lean stack of free CRM, basic aggregators and email tools costs $2k–$5k annually. Adding Grata ($12k–$18k/year) and email automation pushes the total to $15k–$25k. A full institutional stack incorporating PitchBook or Capital IQ ($12k–$40k/year each) and outsourced origination services like Captarget ($2k–$5k/month) reaches $30k–$50k annually.
Each month of search saved is worth approximately $15k–$20k in salary and overhead alone, before counting the option value of acquiring a better company or avoiding a broken deal. Every failed QoE report burns $20k–$30k. The economics of better targeting are unambiguous: even modest improvements in screening quality generate significant savings against these cost structures.
The headline number deserves its own section because it defines the structural risk of the model.
Of 524 concluded US and Canada search funds in Stanford's dataset, 196 (37%) failed to acquire any company. The searcher spent two years, burned through $400k–$500k of investor capital, and walked away with nothing. Since 2014, the acquisition rate has actually declined to approximately 57%, meaning 43% of recent searchers fail to close.
Among those who do acquire, roughly 31% produce losses: 20.5% partial, 10.5% total. Run the compounding probability and the chance of a positive-return outcome for any new search fund is approximately 43%.
International search funds show a notably higher acquisition rate of 79%, though the international ecosystem is younger, more self-selecting, and return data is preliminary.
The reasons for failure cluster around sourcing and discovery. Searchers who fail tend to exhibit identifiable patterns: overly narrow criteria, excessive reliance on brokered deal flow, insufficient outreach volume, delayed first LOIs, and failure to develop proprietary sourcing capabilities. The structural irony is clear. The model's rapid growth simultaneously validates its economics and undermines individual success rates by crowding the buyer side.
The post-acquisition failure rate connects to sourcing quality too. The top reasons for losses include operational complexity the searcher didn't fully understand (63%), board disagreements (59%), poor gross margins (46%), and customer concentration (41%). These are problems that better pre-acquisition intelligence and more selective deal sourcing could mitigate.
The IESE 2024 survey is clear about where searchers look: 64% of international searchers named proprietary search, contacting owners directly, as their primary source of deal flow, against 37% who relied mainly on third parties such as brokers, investment banks and investor networks. (IESE rounds both shares, so they total 101%.) Stanford's Best Practices recommends allocating 80% of search time to proprietary and industry-driven sourcing, with only 20% to brokered deals.
The reason is economics, not ideology.
Research from Axial finds that lower-middle-market companies sourced proprietarily trade at median acquisition multiples approximately 15% lower than comparable brokered deals. Stanford data shows top-quartile search fund performers paid a median 4.5x EBITDA versus 4.8x for bottom three quartiles, while buying larger, faster-growing, and more profitable businesses. The mechanism is straightforward: in proprietary deals, the searcher is often the sole buyer. No competitive auction. No inflated pricing.
The adverse selection problem in brokered deals compounds this. Stanford investors have noted that brokered deals shown to search funds tend to be those already passed on by better-capitalised PE buyers with committed capital. Barriers to entry in business brokerage are low, quality varies enormously, and experienced searchers consistently report that most brokers add limited or negative value to the process.
Proprietary outreach also builds a direct, personal relationship with the seller before commercial negotiations begin. For search fund operators, whose core pitch is a dedicated young CEO committed to preserving the founder's legacy, this relationship quality is the single most important differentiator. In brokered processes, that personal connection is mediated and diluted.
The critical data point that ties all of this together: practitioner estimates suggest over 80% of businesses that ultimately sell are never formally listed with a broker. The vast majority of the market is invisible to anyone who isn't doing proprietary outreach.
The UK was the pioneer international search fund market. The first international fund was raised here in 1992. According to IESE's 2024 data, 35 UK search funds have been raised and 14 acquisitions completed. Spain leads Europe with 67 cumulative funds and 33 acquisitions, followed by the UK, France (21 funds, 12 acquisitions), Germany (20 funds, 10 acquisitions), and Italy (17 funds, 7 acquisitions).
In total, 14 European countries now have search fund activity, with Europe accounting for roughly 180 of the 320 international funds tracked by IESE, making it the world's largest international market.
UK-focused law firms and advisory firms have reported significant growth in ETA transaction activity since 2024. London Business School and INSEAD now offer dedicated search fund modules. The pipeline of new UK searchers is growing: our UK search funds directory lists the funds searching now and what the others bought, and UK search fund deals shows what the sellers had in common.
But the UK search ecosystem has a structural problem that the US doesn't: the broker market for sub-£5M businesses is thin and fragmented. Listing platforms like Daltons Business and BusinessesForSale.com serve primarily the micro-business market (sub-£250K asking prices, too small for most search funds), while SME Market is more search-fund-relevant but thin on inventory. Beauhurst and Endole expose UK company data but leave the searcher to infer who might sell. A newer wave of ETA-specific tools has emerged, with BizCrunch in the UK and AlphaY and ETA IQ internationally bringing purpose-built workflows to searchers. Grata is powerful but US-centric. And Companies House, which holds the richest public dataset of UK company information anywhere, offers raw data but no screening, scoring, or intelligence layer on top of it.
The result: UK searchers face the same 3,000-company funnel as their US counterparts, but with fewer tools and thinner intermediary networks to help them through it.
This is where it gets interesting, and where the gap between the supply of succession-ready businesses and the capacity of searchers to find them becomes visible.
We maintain a database of 3.7 million active UK companies, built from public Companies House filings. When we score these companies for succession and exit signals (director age, tenure, filing behaviour, capital investment patterns, dividend changes, board structure), the scale of the hidden market becomes clear.
852,756 UK companies have an average director age of 60 or above. Of those, 463,253 have a single director: no co-directors, no named successors, no internal succession infrastructure of any kind. 298,262 sole directors have 15 or more years of tenure, the classic founder-operator pattern where one individual has run the business alone for over a decade with no sign of transition planning.
At the sharp end: 21,385 companies are PURSUE-grade on our model, a strong business meeting strong exit signals.
These companies aren't listed with brokers. They aren't on any marketplace. Most of their owners haven't consciously decided to sell. But they match every profile of a business where a conversation about succession would be welcome, and where a well-prepared acquirer with the right approach could find a receptive owner.
This is the market that sits underneath the 3,000-company funnel. The companies are there. The data to identify them is public. What's been missing is the infrastructure to score them, rank them, and deliver actionable intelligence on the ones worth approaching.
Pick a sector, a region, a size and an owner profile and ExitRadar counts the companies that fit, live, from every scored company in the UK, then shows the best-fitting one, with its Exit Score and its identity withheld. 21,385 companies currently carry our top acquisition grade.
The search fund model works. The returns prove it. But the discovery phase is the bottleneck: an extraordinarily inefficient process that consumes 20 months on average, costs £250,000–£350,000, and fails entirely for more than a third of operators.
The fix isn't more cold emails or better CRM software. It's better targeting. If a searcher can start with companies already showing exit signals instead of contacting 3,000 to find them, the entire search compresses. Fewer months burned. Fewer broken deals. More time spent on the 50 companies that actually matter, instead of the 2,950 that never would have sold.
The economics of better screening are stark. One month of search saved: £15,000+. One broken deal avoided: £20,000–£30,000. One proprietary deal closed at 15% lower multiples on a £2M acquisition: £300,000 in value. Against those numbers, the cost of better intelligence is a rounding error.
The businesses exist. The buyers exist. The data to connect them exists. The question is whether searchers will keep grinding through 3,000 companies manually, or start with the ones that are already signalling.
Deal sourcing is the work of finding businesses to buy: building a list of companies that fit an acquisition brief, then turning names on that list into conversations with their owners. Deals come on-market, through brokers and listing sites, or off-market, by approaching owners directly before any sale process exists.
UK deal sourcing tools fall into layers: listing sites such as BusinessesForSale.com, Daltons Business and RightBiz for on-market deals; company-data platforms such as Beauhurst, Endole and FAME for off-market targeting; exit-readiness scoring such as ExitRadar; outreach tools such as Apollo.io and Lemlist; and CRMs. All-in-one ETA platforms such as BizCrunch combine data, outreach and deal tracking, and AI platforms such as Grata and Inven build target lists from a written brief.
The terms are often used interchangeably. Strictly, sourcing builds the list of companies that could be bought, and origination turns names on that list into live conversations with owners. Outsourced deal sourcing companies such as Captarget sell the origination work on a retainer.
Write a buy box (sector, EBITDA size, region), cover the on-market flow through brokers and listing sites, then build an off-market list from Companies House data ranked by owner signals such as an older owner, long tenure and no younger director. Approach those owners directly by letter or email, and track every conversation in a CRM.
According to Stanford GSB's 2024 study and the IESE 2024 International Search Fund Study, the average search fund operator contacts over 3,000 companies to close a single acquisition, with a conversion rate of approximately 0.03% from initial contact to closed deal.
37% of all concluded US and Canada search funds failed to acquire any company, according to Stanford GSB's 2024 study. Since 2014, the failure rate has increased to approximately 43%.
The median search duration is 20 months, with 31% of searchers taking 20-30 months and 18% exceeding 30 months. The international median is longer at 23 months.
In IESE's 2024 survey, 64% of international searchers named proprietary search as their primary deal source, against 37% who relied mainly on brokers and other third parties (both shares are rounded, so they total 101%). Proprietary deals close at approximately 15% lower multiples, with less competition and stronger seller relationships.
This analysis draws on Stanford GSB's 2024 Search Fund Study, the IESE 2024 International Search Fund Study, Stanford's Search Fund Best Practices and Search Fund Primer, Axial deal sourcing research, and practitioner data from the ETA community. UK company data is from ExitRadar's database of 3.7 million active companies, derived from public Companies House filings. Tool and platform details are from publicly available information from each provider as of July–October 2026 and should be confirmed with the provider.
