You find off-market sellers by contacting a large, well-defined set of owners directly and letting timing surface itself. The seven channels that work in the US are owner-direct cold email, LinkedIn, direct mail, state licensing boards, county and permit records, trade associations and events, and professional referral networks. Most serious acquirers run two or three in parallel, because each one reaches owners the others miss.
The premise most buyers get wrong
Most people start by asking how to find owners who want to sell. That question has no good answer, because owners who already want to sell call a broker. By the time they want to sell, they are on-market.
The real question is different: how do you be the person already in the conversation when an owner starts thinking about it? At any moment, a small slice of any owner population is quietly weighing an exit. Health, partnership friction, a big customer loss, a good year, a competitor selling well, a child not interested in taking over. None of that is visible from the outside, and none of it is searchable.
So you contact a lot of owners who fit your criteria, and you let timing reveal itself. That is why volume with precision beats both spray-and-pray and hand-picking a shortlist of twelve.
One reply from a Florida HVAC owner makes the point:
"Short answer: yes, I'm actively in conversations now. Florida residential HVAC, $1.6M revenue. Running live discussions with PE-direct buyers and brokers this week."
He was already selling. We had no way to know. He was on the list because he matched the profile, and the email arrived while the question was live.
1. Owner-direct cold email
Best for: reaching thousands of owners across a defined trade and geography, quickly.
This is the highest-volume channel and the one with the clearest economics. Build a list segmented by trade, revenue band, headcount and county, verify the addresses, and run a short two-to-five step sequence written for owners rather than for brokers.
What matters more than anything: segment tightly enough to say something specific. On one Florida programme we ran eleven separate campaigns rather than one, so an HVAC owner and a behavioural health group never received the same message. That produced 39 interested sellers from 9,574 owners contacted.
Cost: $2,000 to $8,000 a month managed, or a few hundred in tooling plus significant internal time if you run it yourself.
Watch out for: sending from your own domain. Do that and your firm's email deliverability degrades within weeks. Use separate warmed domains, always.
2. LinkedIn outreach
Best for: owners who ignore email, and for warming a name before the email lands.
LinkedIn works well as a second touch rather than a first one. A connection request from a real profile, followed a few days later by an email, performs better than either alone, because the name is now familiar.
It is slower and more manual than email, with hard daily limits. For owner-operated trades businesses, LinkedIn presence is also patchy: many excellent acquisition targets have no meaningful profile at all.
Cost: Sales Navigator plus time, or bundled into a managed retainer.
Watch out for: automation tools that risk account restriction. Slower and safer is genuinely better here.
3. Direct mail
Best for: older owner demographics and trades where email data is thin.
Physical mail is unfashionable, which is exactly why it works in some segments. A well-written letter to a 62-year-old plumbing company owner who never checks the info@ inbox can outperform ten emails. Response rates are low but the responses tend to be serious.
Cost: roughly $0.75 to $2.50 per piece all-in, so a 2,000-owner campaign runs $1,500 to $5,000 per touch. Materially more expensive per contact than email.
Watch out for: the feedback loop is slow. You will wait weeks to know whether it worked, which makes iteration expensive.
4. State licensing boards
Best for: licensed trades and healthcare practices.
This is the most underused public data source in US deal sourcing. Most states publish searchable registries for contractors, HVAC, plumbing, electrical, roofing, cosmetology, and a wide range of healthcare licences. Records typically include business name, licence type, status, issue date and often the owner's name.
The issue date is the useful part. A licence issued in 1994 tells you the owner has been operating for three decades, which correlates strongly with being near retirement. That is a targeting signal you cannot buy from a data vendor.
Cost: free, plus the work of extracting and cleaning it.
Watch out for: formats vary wildly by state, and terms of use differ. Check each state's terms before bulk extraction.
5. County records and permit data
Best for: confirming size and activity when revenue data is unavailable.
Building permits, business registrations, fictitious name filings and UCC liens are public in most US counties. Permit volume is a surprisingly good proxy for how busy a contractor actually is, and UCC filings reveal equipment financing, which tells you something about asset base and lender relationships.
This is rarely a sourcing channel on its own. It is an enrichment channel: it tells you which names on your list are worth prioritising.
Cost: mostly free, occasionally small per-search fees.
Watch out for: it is labour-intensive and inconsistent between counties.
6. Trade associations and events
Best for: credibility and warm introductions in a specific vertical.
Member directories are effectively pre-qualified lists of established operators. Conference speaker and exhibitor lists are better still, because appearing on one signals a level of commitment and seniority.
We have seen this work outside M&A too. In a software campaign, a list of AI conference speakers produced a 41.4 percent positive reply share, against 28 percent for a much larger list of technology leaders. People who show up publicly for a topic are already engaged with it.
Cost: membership and event fees, plus travel.
Watch out for: it does not scale. Excellent for a focused thesis, useless for covering a whole state.
7. CPA, attorney and wealth-manager referrals
Best for: the highest-quality, lowest-volume flow you will ever get.
Accountants, transaction attorneys and wealth managers know an owner is thinking about selling long before anyone else, often years earlier. A referral from a trusted advisor arrives pre-warmed in a way no cold email can match.
The catch is that this network takes years to build and cannot be switched on when you need deals this quarter. Treat it as a long-term compounding asset rather than a channel you activate.
Cost: time, reciprocity, and sometimes referral fees where permitted.
Watch out for: referral fee arrangements can carry licensing implications depending on the state and the professional involved. Get advice before formalising anything.
How to stack them
Nobody should run all seven. A practical stack for most acquirers:
- Licensing boards and county data to build and prioritise the list, at no data cost.
- Owner-direct cold email as the volume engine that produces conversations this quarter.
- LinkedIn as a second touch on the names that matter most.
- Referral network built patiently in the background, because in five years it will be your best source.
Add direct mail only where the demographic justifies the cost, and events only where your thesis is narrow enough to make a single conference worthwhile.
One warning on measurement. Judge these channels on positive reply share, not raw volume. Our best-performing M&A campaign ever was also one of the smallest: about 1,263 physical therapy clinic owners in New York, which returned a 45.5 percent positive share. The largest campaigns did not produce the best rates.
Frequently asked questions
What is an off-market business sale?
One where the company was never publicly listed with a broker or marketplace. The buyer approached the owner directly, or the deal came through a private referral. Off-market deals usually mean less competition and lower multiples.
How do you find business owners who want to sell?
You generally cannot, because owners who want to sell go to brokers. Instead you contact a large, well-defined set of owners who fit your criteria and let timing surface itself.
Is it legal to cold email business owners in the US?
Yes, under CAN-SPAM, provided sender identity is accurate, a physical address is included, opt-outs are honoured promptly, and subject lines are not misleading. See our compliance section for detail.
How many owners do I need to contact to find one deal?
It varies enormously by sector and message quality. As a rough planning figure from our own campaigns, contacting around 10,000 owners in a defined trade and geography produced roughly 40 seller conversations. How many of those become closed deals depends entirely on your diligence and terms.
