WestStar Physical Therapy: add-on targets for a buy-and-build

The mandate

A physical therapy platform pursuing add-on acquisitions. The target universe is clinic owners: small, local, owner-operated, and almost entirely absent from the databases that buyers normally work from.

That absence is the defining feature of the job. A platform can licence every data product on the market and still not have a usable list of the twenty clinics inside its drive-time radius that fit, because the businesses are too small to be covered and their owners are not looking. The sector detail is in physical therapy acquisitions sourcing.

What it produced

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.

Why add-on search is a different job

Buyers consistently underestimate add-on acquisition sourcing because it looks like a smaller version of platform search. It is not.

The companies are smaller, so there is less public information and the owner is the entire decision, with no board and no adviser to persuade. The reason to sell is usually personal rather than financial: 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 has to be written for a clinic owner rather than for a CFO, the follow-up runs in months because that is genuinely how long the decision takes, and a small universe has to be worked patiently instead of burned through in a quarter. A programme built on platform-search assumptions produces a quiet list and a disappointed sponsor. The broader framing is in add-on acquisitions and buy-and-build sourcing and portfolio company deal sourcing models compared.

How to resource an add-on search properly

Size the universe before you price the programme. If there are 60 fitting clinics in the radius, no amount of budget produces 200 conversations, and any provider promising otherwise is planning to email companies that do not fit.

Then 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. how the origination engine works covers how the follow-up is run, and lower middle market deal sourcing covers what changes as targets get smaller.

Two failure modes account for most disappointing add-on programmes, and both are set before launch. The first is a universe defined by industry code rather than by whether the platform would actually want the business: it looks larger on the spreadsheet and produces conversations with owners nobody intends to buy. The second is measuring an add-on search on platform-search timelines, then cancelling it in month three because the monthly numbers look small. They are supposed to look small. Fifteen conversations inside one drive-time radius is a large share of the reachable universe, and the right comparison is against that universe rather than against a national campaign.

The third thing worth deciding early is who at the platform takes these calls. A clinic owner who agrees to talk wants to speak to an operator who understands what running a clinic is like, not to 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.
