Deal Sourcing: How PE Buyers Reach Owners Before a Sale
Deal sourcing that reaches the owner before a banker is hired, for PE firms, corporate development and HoldCos, from public registers to the first message.
Buyer type, ticket, region, sector and a ruled-out list go on one page before anyone searches or calls an owner.
Patent filings, licences, contract awards and customs records show a company before a private-company database ranks it.
78% of family business executives expect a CEO transition within a decade, and only 23% are putting a succession plan into practice.
Say whose side you're on, ask about a majority stake, state that the owner pays nothing and hold the buyer's name back.
Salaries, a platform licence and a calling campaign are paid with or without a deal; a sourcing mandate adds a success fee on completion.
Deal sourcing is the work of finding private companies a buyer could acquire and getting their owners talking before a banker is hired to sell them. A buyer who skips it sees mostly banked sales, where every bidder reads the same memorandum against the same bid date.
PE deal teams run it for platforms and add-ons, HoldCos for their next company, and corporate development teams run M&A deal sourcing for a strategic acquirer.
Someone has to make the first call to each owner, whether that's your own deal team, a calling agency working your script, or an advisor holding a deal origination mandate on your behalf.
| Item | Buyer drives it (0 to 100) | Before any sale (0 to 100) | Note |
|---|---|---|---|
| Banked auction | 10 | 10 | |
| Broker-led sale | 24 | 28 | |
| Owner calls in | 40 | 48 | |
| Calling campaign | 66 | 58 | |
| In-house outreach | 90 | 72 | |
| Sourcing mandate | 90 | 88 |
What is deal sourcing, and when is deal flow proprietary?
A company reaches a buyer in one of three ways. A banker or broker brings it already for sale, with a confidential information memorandum and a bid date attached. Or the owner phones in unprompted, or the buyer's side finds the company and asks the owner first.
Deal flow is the volume all three produce. Sourcing is the work behind the third route, and proprietary deal flow is what it yields, companies that reach you outside a banked process with no auction running and no seller setting the timetable.
On a control deal, I'd pay for the third route before the other two. Bain's 2026 private equity report finds the average process has "dozens of PE firms kicking the tires, most of them looking at the same deal book", and only one of them ends up owning the company. A buyer the owner already knows can put an offer in before the banker's book reaches the other bidders.
Inbound calls are worth answering, but they come from owners who've already decided to sell and will want more than one offer.
Private equity deal sourcing starts with a written thesis
A search that opens in a database returns every company with the right industry code. So the criteria go on paper before the first search runs.
The sheet below is an illustrative example for one buyout search, and its five lines are enough to run it.
3 columns. Drag the table sideways; the first column stays put.
Field | What to write | Illustrative example |
|---|---|---|
Buyer and deal type | Who acquires, and whether it takes control, adds on or buys outright | A private equity firm, majority buyout |
Deal size | Equity ticket or enterprise value per company | $30M to $50M equity ticket |
Region | Where the headquarters and most revenue have to sit | Germany, Austria and Switzerland |
Sector and revenue model | The business the buyer knows how to own | B2B software with recurring contract revenue |
Ruled out | Companies and situations nobody approaches | Already in a banked sale; services-led revenue; names the team knows |
Teams tend to leave the ruled-out line for later, which is how a search ends up calling owners the firm passed on years ago. Companies your partners already know go on it at the start, and a company with a banker already hired goes on it too, because the off-market advantage is gone. Recheck it whenever a sell-side process starts in your sector while the search is running.
Ownership structure belongs on the sheet as well. Our ledger entry for a 2023 bolt-on, a European value-added distributor a client went on to buy, reads "We screened it out of a universe of forty on ownership structure before contacting anyone."
Where do off-market companies show up before a database lists them?
Private-company databases rank businesses on reported revenue, press coverage and web traffic. A profitable manufacturer that files thin accounts and has never hired a marketing team ranks low in them, or isn't there at all.
Off-market deal sourcing starts from the public record a thesis points to. A company turns up there when something changes, often long before a database catches up.
3 columns. Drag the table sideways; the first column stays put.
Thesis | Public record to read | What it shows early |
|---|---|---|
Medical device makers about to launch in the US | FDA clearance decisions | A newly cleared device, long before the US revenue it brings shows anywhere |
Industrial technology that owns its IP | Patent office registers | Published applications and grants by applicant |
Payments firms entering a new market | Financial regulator registers | A payment or e-money licence on the day it's granted |
Infrastructure services on public contracts | TED in the EU, Contracts Finder in the UK | Contract awards with their value, for firms that publish little |
Food manufacturers growing through exports | Customs records, such as US import bills of lading | Shipments up year on year, and who's buying them |
The USPTO publishes most patent applications about 18 months after filing, so an engineering-led company's technology is public well before anyone writes about the company. The EU's TED platform puts out more than 3,000 procurement notices every working day.
We've run the FDA route, on a search in a sector that needs the agency's approval; the other rows are examples. If a thesis can't name the register its targets appear in, it's usually too broad to source off-market, and it needs tightening before anyone is paid to search.
Which owners will take a first call?
An owner who isn't selling still takes some calls, mostly once the question of who runs the business next is on the table. In family businesses it often is.
In a February 2026 Deloitte Private survey of 300 family business executives, 78% expected a CEO transition within the next decade, and 42% within three to five years. Only 57% had a succession plan and 23% were putting one into practice, which leaves 43 in 100 with no plan and 34 with one that exists on paper only.
A sale to a buyer who keeps the business running is one way to close that gap. In a second Deloitte survey, of US private companies already planning a sale or transfer, business continuity was the main driver at 40%, ahead of liquidity for the business at 22% and for the owners at 13%.
A succession trigger opened a 2023 bolt-on we sourced for a buyer, an installer of building systems in Europe sized at EUR 10-25M. We approached the owner-manager directly and kept the acquirer's identity back until the second conversation, and the deal closed.
What should an owner read in the first message?
The first message decides whether an owner who isn't selling writes back. Each line in it should answer a question the owner would otherwise have to ask, so five things go in.
The sender acts for a buyer, says so, and names the buyer type, such as a private equity firm or a strategic acquirer.
One plain question asks if the owner would discuss selling a majority stake. An owner who won't give up control answers it in a line.
The buyer pays the advisor, and the owner reads that before wondering about it.
The buyer's name comes once both sides want to meet, and no earlier.
A short call is the only next step.
A price, a deadline, a request for documents and any mention of other companies on the list stay out of it. On a no-names basis, an owner who declines never learns who was asking.
Open on what happens to the business and its people, the reason Deloitte's survey puts ahead of either kind of liquidity.
Approach each company once per thesis and log every answer, whether it's a no, silence, not now or a yes. Without that log, a second caller from your side reaches the same owner a month later.
Decide who takes the first meeting before any message goes out, so an owner who agrees to talk meets someone who can say yes.
From the desk. "A consumer brand that was never on the market, bought by a platform that had never been shown it." That's our buy-side ledger's line for a deal where spectup worked for the buyer alone, a US platform that buys consumer brands and runs them together, and was paid by it.
The company was found and approached off-market, and the acquisition, about $12M, closed. It's one of the deals behind spectup's $150M+ M&A advised.
Four ways to staff the search, and how each is paid
Between a thesis and an introduction, the deal sourcing process runs through six steps, from building the list and researching each company to writing the approach, contacting the owner, qualifying the answer and making the introduction. The route a buyer picks decides who carries each step and when the bill arrives.
| Scenario | Buyer's own team | Outside provider | Gap |
|---|---|---|---|
| In-house deal team | 6 | 0 | 6 |
| Sourcing platform | 5 | 1 | 4 |
| Outsourced calling team | 2 | 4 | 2 |
| Sourcing mandate | 0 | 6 | 6 |
In-house deal team. You pay salaries and the partners' time whether or not a deal completes, and the team does all six steps itself.
Deal sourcing platform. The licence fee is owed with or without a deal. The database builds the list, and your team does the other five steps.
Outsourced calling team. Campaigns are billed monthly, deal or no deal. Callers work your script on a sequence, often in your name, and hand over a booked meeting you qualify yourself.
Sourcing mandate. You pay a monthly retainer, and a success fee only if a deal completes. The advisor runs all six steps and contacts each owner one to one.
Proactive firms in Bain's 2026 report go looking for companies in their sweet spot "often years before there's a hint they are about to trade". On an in-house desk, those years of tracking are salaried hours spent on companies that may never come to market.
I'd keep sourcing in-house where conflicts worry you most, since no outside firm sees the list. The cost is timing. A desk running two live deals rarely has a spare week when an owner's trigger appears, and an owner who turns down your own analyst has turned down your firm by name.
Ask any sourcing firm who else it searches for in your sector. If the answer includes a competitor, your target may already have been offered to them.
Ask, too, what happens to the work if no deal completes. A sourcer that keeps the company list and the approach log at the end has been paid to build an asset it can sell to the next buyer.
When proprietary deal flow fits a deal, and the pricing risk it brings
Off-market deal sourcing needs a written thesis, funding an owner can see is committed, and enough time for an owner who wasn't planning to sell to make up their mind. A target that has to sign within weeks is better bought in an auction, where the bid date already exists.
Bain's 2025 private equity outlook put add-on transactions at 11% of buyout deal value in 2024, against a peak of 40% in 2015, because higher financing costs made bolt-ons less affordable.
An add-on programme sourced off-market has to price each bolt-on on its own numbers. No auction sets that price, and the easy mistake is paying a platform multiple for a small company.
How spectup runs a sourcing mandate for one buyer
On a deal sourcing mandate, spectup acts for the buyer only, whether that's a PE firm buying a platform or an add-on, a corporate development team or a HoldCo, on equity tickets or acquisitions from about $30M. The buyer mandates and pays us; the owner pays nothing and never has us as an advisor on the same transaction.
| Step | Leads to |
|---|---|
| Criteria sheet (Written with the deal team) | Company universe |
| Company universe (Databases, registers, own scrapers) | Matches checked |
| Matches checked (Scored, then verified by hand) | Direct approach |
| Direct approach (Phone, email, LinkedIn) | Qualifying call; Owner declines |
| Owner declines (Buyer's name never shared) | end |
| Qualifying call (Appetite, stake, timing) | Introduction |
| Introduction (With the owner's consent) | end |
The universe is one record per company, drawn from private-company and deal databases, the public registers the thesis calls for, and scrapers our team builds for each search. An AI model scores each company's website, product pages and job posts against the criteria, and a person on the team checks every match before anyone is approached.
“Their work significantly expanded our access to potential acquisition targets and helped us identify and engage with opportunities we wouldn’t have found otherwise.”
Laurent TrucSVP Business Development, Society Brands
We approach each owner one to one by phone, email and LinkedIn, never from a bulk list or an automated sequence. An owner who's open to talking gets a qualifying call on appetite, stake and timing, and the introduction follows only with that owner's consent, ahead of any banked sale.
We never approach one company for two clients at once; the client whose mandate was signed first goes first. spectup charges a retainer for each month the search is live, plus one success fee, payable when a deal with a company we introduced completes.
Both fees are capped and priced on deal size and regions. If no deal follows, the client still keeps the criteria sheet, the universe, the log of every approach and the company profiles.
The mandate ends at the introduction. After it, buyer and owner usually sign a non-disclosure agreement and then a letter of intent, and the full data room opens once the letter is signed.
A buyer who wants that stretch run through to signing hires buy-side M&A advisory for it.
Test one thesis against one register before you pick a route
Take the thesis with the clearest public record behind it and pull a year of entries from that register, such as clearances, patent grants or contract awards. Then check how many of those companies your current database lists, and how many your team has ever spoken to.
If most of that year's register is missing from your database, a platform licence won't carry this thesis on its own. The register companies nobody on your team has spoken to each need a first call. If that group is larger than your team can call alongside its live deals, the search needs outside hands; if it's short, keep it on your own desk.
Three conclusions
An owner your firm passed on once, called again by a stranger from the same firm, reads it as a firm that doesn't know its own list. The ruled-out line prevents that.
A first message that talks price answers a question the owner hasn't asked and gives a company that isn't for sale a reason to stop reading.
If it works for two buyers in your sector, it sets the order, and the owner won't tell you who got there before you.
Deal sourcing: questions readers ask
5 questions on M&A, answered by Edwin Mik, Partner & Head of IR.
01What does deal sourcing mean?
Identifying private companies that fit a buyer's criteria and getting each owner into a conversation, ideally before a banker runs a sale. M&A deal sourcing for a corporate acquirer is the same work under another name.
02What does a deal sourcer do?
A deal sourcer turns a buyer's criteria into a list of companies, researches each one and contacts the owners. They ask one question about selling a majority stake, then qualify the owners who say yes on appetite, stake and timing. The ones still interested are introduced to the buyer. A sourcer hired by a buyer is paid by it, so the owner pays nothing.
03What is deal sourcing in private equity?
Private equity deal sourcing is the search for companies a PE firm could buy a controlling stake in, for a platform or as an add-on. A control deal ends with one buyer, so PE firms try to reach owners before a banked auction starts.
04What are the best online deal sourcing platforms?
Private-company databases show ownership, size and past deals, deal marketplaces list companies whose owners already want to sell, and CRMs track your team's relationships. Test any of them on companies you already know in the region, for how many owner-managed ones it lists and how current its ownership data is.
05When should a private equity firm outsource deal sourcing?
When the desk has no free week in the month an owner's trigger appears, when the firm wants its name held back until an owner agrees to meet, or when the thesis covers regions where the team has no line to owners. spectup runs such searches as sourcing mandates for buyout firms, corporate acquirers and HoldCos, on deals of about $30M and up. We act for the buyer only and are paid by it, a retainer for each month of the search plus one success fee if a deal we introduced completes.
