About Audax Private Equity

Audax Private Equity is a Boston-based middle-market firm best known for its buy-and-build strategy, which involves acquiring a platform company and aggressively executing add-on acquisitions to scale it. Within healthcare, the firm focuses on care delivery and tech-enabled service companies. Audax is a generalist middle-market investor with a substantial healthcare practice and is not described as AI-focused in the source data.

Check sizes are $25M+, with overall transaction sizes climbing higher when add-ons are included. Deployment is concentrated in the United States. The firm engages at growth and buyout stages and is well known among bankers running middle-market healthcare processes.

For healthcare AI founders, Audax is relevant only at scale. The right founder profile is one running a profitable services or tech-enabled services platform that could anchor a buy-and-build, or whose company could serve as an add-on to a current Audax portfolio company. Seed and Series A AI founders should not approach.
