Investment thesis

Eir Partners invests exclusively in healthcare technology and tech-enabled services, partnering with companies and founders identifying novel solutions to some of the trickiest problems in the healthcare sector. The firm concentrates on four core areas: payor services and technology, provider payments and technology, pharma services and technology, and B2B healthcare services and platforms. Since 2015, Eir has taken an operator-led, partnership-focused approach, combining deep sector experience with hands-on execution. Each investment is co-led by an Eir Deal Partner and an Eir Operating Partner embedded in execution across finance, technology, go-to-market, human capital, and M&A. Targeted stages of investment include growth equity through control buyouts, with equity check sizes ranging from $40–$150 million or larger with co-investments.

Notable quotes
