U.K. performance marketing agency Brainlabs said early on Tuesday it’s acquiring U.S. digital agency Hanapin. It’s the latest example of how newer agencies are also becoming dealmakers in the agency industry, where for a time legacy advertising holding companies were the dominant merger participants.

The terms of the deal were not disclosed. A source familiar with the matter said the deal’s value is in the low double-digit millions.

Last year Brainlabs sold a 40% stake in its business to private equity firm Livingbridge. Brainlabs CEO Daniel Gilbert said on Monday this maneuver gave Brainlabs more firepower to make acquisitions. (Earlier this month Brainlabs said it plans to acquire London-based search engine optimization agency Distilled.)
