Job Title

Investor and Director


Tray.io is an internet company that specializes in Development, API, Integration.


I back teams building remarkable software-driven companies. I often partner with them from the start of their journeys and invest large cheques in a small number of companies. I have chosen to operate as a solo investor as there is no greater privilege than supporting founding teams as fully as I can. My success as an investor is only possible because of them. So I always put the interests of our companies first. I am drawn to distinctive, original startups, and frequently invest in less obvious opportunities that require some vision. If they succeed fully, they will become enduring companies with important positions in global markets. This success will be built on accumulating advantages, technical moats, and attractive economic models and therefore ultimate self-determination. I have had the good fortune to invest early in a wide range of great companies including King.com, Houzz, The Foundry, Tipalti, Ubiquisys, Boxed, eDreams, QXL.com, and Seal Software. In the last few years, I invested early in emerging platforms like Bryter, Harbr, Illumio, Lokalise, Reveal, Snyk, Tipalti and Tray.io, and a wide range of unannounced investments. I was honoured to be included at number six in Forbes' first Midas List Europe. Without the adventurous entrepreneurs that I've enjoyed working with over the years, this wouldn't have been possible, and I am thankful to this very special group of people.

Is based in London, England, United Kingdom.
