Martlet Capital has invested in more than 65 start-ups, since its launch in 2011. In 2021, Martlet successfully raised additional capital to scale its investment activity. 

We provide patient capital for early-stage B2B deep technology and life science start-ups, with a primary focus on companies based in Cambridge.

Our team is comprised of experienced investors and entrepreneurs. In addition to capital, we can offer support, experience and a network of contacts.

We have achieved several exits from our portfolio, from trade sales to global technology companies and IPO’s.
