ENABLING GREEN INNOVATION TO THRIVE
2026 EVENTS
THE ULTIMATE MEETING PLACE FOR THE CLIMATE TECH ECOSYSTEM
Cleantech Venture Day is the Climate Tech SuperCluster’s flagship event series, bringing together founders, investors, corporates and city partners to help climate tech move from promise to real-world deployment.
The series takes place in Amsterdam, London and Paris, with each edition is built around a clear theme and a carefully curated room. The result is a day that blends pitching with high-signal conversations across venture capital, large enterprises, infrastructure players and the public sector.
Since 2006, startups pitching at the series have raised more than $650 million. Beyond capital, the series helps founders build partnerships, secure pilots and connect with organisations that can support real-world deployment.
The day is built around a simple idea. Bring together a highly curated group of organisations from across the Climate Tech SuperCluster region, then give them the time and structure to connect properly. Expect a selected line-up of pitching companies, practical discussions, and space for the introductions and follow-up that make the series worth coming back to.
