Our team

Our team of investment professionals based in London, Munich and San Francisco combines technology, operational, corporate, legal and venture capital experience in both Europe and the U.S. Every team member contributes to the success of our investments along with the substantial resources of the Doughty Hanson Group.

We pride ourselves on being approachable and easy to talk to. We are happy to be contacted directly by entrepreneurs keen to discuss business opportunities and find out more about us or our portfolio companies. We also encourage entrepreneurs to approach us before their businesses need funding. This gives us an opportunity to get to know one another, possibly entering into an early dialogue and sharing ideas without the pressure of the fund raising process.

We attend and sponsor a number of industry events every year, both in the UK and in other European countries, so come and meet us personally to talk about your business ideas.
