What is an add-on acquisition?

An add-on acquisition is a smaller company bought and combined with an existing platform company to add services, customers or geography. Add-ons usually need less capital than the platform deal and can raise the platform's value quickly when integration goes well. They are one of the most common ways private equity firms grow portfolio companies.

Why it matters to a revenue leader

For a revenue leader, every add-on brings sellers, customers and habits that differ from yours. The deal model often counts on keeping the acquired customers and selling them more services, and both depend on the sales integration. The risk sits in the first months: overlapping accounts, unclear ownership and anxious sellers can cost renewals before anyone notices. Research on mergers names unresolved ownership of overlapping accounts as a common source of lost revenue.

Example

Fictitious numbers

A commercial HVAC platform with 20 sellers buys a 6-seller service company in the next state. Of the add-on's 900 customers, 140 also buy from the platform. The CRO names an owner for each shared account before closing so no renewal goes unworked.

The question to ask

"Who owns each shared account on day one, and who is watching renewals at the acquired company?"
