Add-on acquisition sourcing for buy-and-build platforms

The problem

The targets are real and no database has them

A platform pursuing add-ons is looking for small, local, owner-operated businesses inside a drive-time radius. That universe is almost entirely absent from the databases buyers normally work from, because the companies are too small to be covered well and their owners are not looking.

A platform can licence every data product on the market and still not have a usable list of the twenty businesses in its own region that actually fit. Meanwhile the brokered flow that does exist is intermediated, priced accordingly, and shown to everyone, which is the argument in off-market versus auction pricing.

Why it is a different job

Add-on search is not a smaller platform search

Buyers consistently underestimate add-on acquisition sourcing because it looks like a smaller version of what they already do. It is not, in four specific ways.

The companies are smaller, so there is less public information and more of the qualification has to be done from the approach itself. The owner is the entire decision, with no board and no adviser to persuade. The reason to sell is usually personal: retirement, a clinical career someone no longer wants to run as a business, a lease coming up. And the geography is fixed by the platform, so the universe cannot be widened when it goes quiet, which is the usual escape hatch on a platform search.

The practical consequences: the approach is written for an owner rather than a CFO, the follow-up runs in months because that is genuinely how long the decision takes, and a small universe is worked patiently instead of burned through in a quarter. The wider framing is in add-on acquisitions and buy-and-build sourcing and portfolio company sourcing models compared.

Proof

A physical therapy platform

For WestStar Physical Therapy, a clinical platform pursuing add-ons, the engine opened 15 positive conversations with clinic owners inside the platform's geography and size band. Every one came from a direct approach to the owner rather than through an intermediary, which in this category is the only way the conversation happens at all.

Fifteen sounds small until you set it against the universe. In a fixed drive-time radius that is a large share of everything reachable, and the right comparison is against that universe rather than against a national campaign. Measuring an add-on search on platform-search timelines, then cancelling it in month three because the monthly numbers look small, is one of the two failure modes we see most.

How we resource it

Size the universe before you price the programme

If there are 60 fitting businesses in the radius, no budget produces 200 conversations, and any provider promising otherwise is planning to contact companies that do not fit. So the first thing we do is count the universe, and if it is too small to support a programme we say so before you pay for one.

Then we plan for a long nurture. On a fixed universe the win comes from being the buyer the owner remembers when their circumstances change, not from catching them in the quarter you happened to start. That means the follow-up is resourced for months rather than weeks, and a "not now" is logged as an asset rather than a loss.

The third decision is who takes the call. A clinic owner who agrees to talk wants an operator who understands running a clinic, not a corporate development analyst. On a buy-and-build the platform's own operators are the strongest asset in the conversation, and programmes that route around them convert worse for reasons that have nothing to do with sourcing. how the engine works covers the handoff.
