Off-market deal sourcing: how to build proprietary deal flow.

Off-market deal sourcing is the practice of originating acquisitions directly from owners, through advisor networks, thesis-led outreach, operator scouts, data screening and verified buyer networks, before the business enters a competitive process. Done well, it typically gets you in 0.5x–1.5x of EBITDA below auction clearing prices, with exclusivity and enough time to diligence properly. In the lower mid-market, most sellable businesses never reach a formal process at all: the owner sells to whoever built the relationship first. The funds that compound best treat origination as an engine with a weekly cadence, not an inbox they check.

Why does proprietary deal flow beat auctions?

Three reasons, and they compound.

Price. An auction exists to manufacture competitive tension. Remove the tension and you remove the premium. In our deals, a proprietary conversation with a founder typically lands 0.5x–1.5x of EBITDA below where a banked process for the same asset would clear, on a £3m EBITDA business at a 6x auction price, that is £1.5m–£4.5m of entry value.

Exclusivity. No bid deadlines, no staged data room, no seller's advisor rationing management access. You get time to meet the team, test the customer base and structure earnouts or rollover equity that an auction timetable would never allow. That is where the deals with real deferred consideration get done.

Relationship. Founder-led and family-owned sellers disclose more to a buyer they trust, transition better, and stay on when you need them to. The relationship you build over six months of origination is the same one that carries you through the first hundred days of ownership.

Be honest about the trade-off: off-market does not mean cheap, and it does not mean easy. Conversion rates are low, timelines are owner-driven, and half the businesses you meet are not ready to sell. That is exactly why a repeatable engine beats opportunism, and why you should know the red flags that kill deals in diligence before you fall in love with a proprietary one.

Which five sourcing channels work in the lower mid-market?

1. Advisor networks

Accountants, lawyers, wealth managers and boutique sell-side firms see mandates months before the market does. The job is to become the buyer they call first: a one-page mandate they can forward, fast responses, and a track record of closing. This is why serious acquirers register with sell-side networks, our own verified buyer network holds 5,000+ buyers and, because 80% of the mandates we take reach close, sellers accept introductions from it.

2. Thesis-led direct outreach

Pick a niche you can underwrite, a sector, a size band, a geography, and write to owners with a specific, credible reason you want their business. Generic "we buy companies" letters convert at close to zero; a real thesis with a named angle typically gets a 2%–5% response rate. Volume matters: a serious campaign is 300–500 owners over two to three quarters, not 40 emails in a week.

3. Operator networks

Former founders, sector executives and your own portfolio managers hear about tired owners years before any advisor does. Formalise it: give operators your thesis, pay introduction fees of roughly 0.5%–1.5% of enterprise value on completion, and debrief them after every lead. One well-connected operator in a niche is worth more than any database.

4. Data-driven screening

Filed accounts, hiring patterns, review velocity, import records and web traffic let you build a ranked universe before anyone else is looking. The useful filters are simple: 10+ years trading, stable or growing margins, owner aged 55+, no institutional shareholders, no recent fundraise. Screening finds the list; the other four channels open the door.

5. Buyer networks

Verified buyer networks sit between proprietary and intermediated: deals are advisor-prepared, so the numbers hold up, but distribution is limited to a matched shortlist rather than a 200-name auction blast. You trade some price advantage for prepared information and an 80%-style close rate. Our active deals run this way, founder-led businesses in the 8–9 figure revenue range across the UK, US, Europe and Middle East.

What are typical entry multiples in the lower mid-market?

Anchor your outreach and your indicative offers to real bands. Typical lower-mid-market ranges we see across £100m+ of closed transaction value:

• Consumer brands. 3.5x–9x EBITDA depending on category, scale and channel mix.
• Services businesses. 3.5x–9x EBITDA, with recurring contracted revenue at the top of the band.
• Software and apps. 6x–15x EBITDA, or 2x–4.5x revenue where growth justifies it.
• Agencies. 3.5x–7.5x EBITDA, keyed to client concentration and founder dependence.
• Distribution. 3.5x–7x EBITDA.
• Sub-$500k earnings. Buyers price on SDE, typically 1.8x–4.2x.
• Funnel maths. From 300–500 targeted approaches expect a 2%–5% response, 10–25 first meetings, 3–6 businesses worth a valuation conversation, and 1–2 signed LOIs per year per thesis.

How do you build a repeatable origination engine?

1. Write the thesis down. One page per thesis: sector, size band, why you win, what you pay. If you cannot state why an owner should pick you, neither can they.
2. Build the universe once, refresh quarterly. 300–500 qualified targets per thesis from screening, ranked by fit and likely readiness.
3. Run a weekly cadence. A fixed block for outreach, follow-ups and advisor calls. Origination fails as a spare-time activity; it works as a standing meeting.
4. Track everything in a CRM. Every owner contact, every "not yet", every advisor conversation. Most proprietary deals close 12–24 months after first contact, so the pipeline is the asset.
5. Give fast valuation feedback. Owners stay engaged with buyers who tell them a credible number early. Indicative bands beat silence.
6. Protect your close rate. Advisors and operators route deals to buyers who complete. Retrade twice and the referral channel dries up for years.

Sequencing matters too: decide whether each thesis is hunting a platform or feeding an existing one, because platform and bolt-on deals need different lists, different multiples and different owner conversations.
