Cleantech Venture Day has been a trailblazing event for the cleantech community since it started in Finland in 2006. Over the last 12 years, more than 220 companies have pitched their ideas at Cleantech Venture Days and as much as 600 million euros has been invested as a result of the events.

This is the second year that Cambridge Cleantech is hosting Cleantech Venture Day in London. Investors attending this year’s event include Engie, Cleantech Capital Advisors, First Imagine!, Sustainable Technology Investors Ltd, Grid VC and Saffron Myhill-Hunt, among others.

Martin Garratt, CEO of Cambridge Cleantech, said that this year’s line-up represented some of the best SMEs in the cleantech sector: “It was a difficult job for the judges to reduce a strong line-up of 50+ innovative companies to just 24. We are delighted to have companies from Oxfordshire, where we are establishing Oxfordshire Greentech, the equivalent of Cambridge Cleantech, among the top 24.”

KPMG, JA KEMP, Hewitsons, Chubb and Oxfordshire Greentech are event partners for Cleantech Venture Day 2018. Dr. Henry Hunt-Grubbe, an attorney at patent firm JA Kemp, said, “I’m delighted to be involved in this competition for the second time. The quality of the companies is excellent, and I look forward to discussing the interesting technologies and investment opportunities.”
