Greenbackers & Daysix Present: Voices from the Cleantech Ecosystem

23 September 2025

… a podcast series recorded at Sustainable Ventures in London, 2 July 2025.

At Greenbackers, we believe that climate ventures don’t just need capital — they need a connected, collaborative ecosystem of support to grow and thrive. That’s why, alongside our bi-annual Climate Investment Showcase, we’ve built deep partnerships with organisations across finance, law, IP, grants, accelerators, executive search, and beyond.

At our most recent Greenbackers Showcase on 2 July 2025, held in partnership with Sustainable Ventures in London, we invited some of these partners — along with select ventures and sponsors — to sit down for a series of short podcasts. Produced in collaboration with our trusted digital partners Daysix, these conversations shine a light on the diverse and valuable ecosystem behind Greenbackers.

Hear from the people and organisations helping to accelerate the transition to a cleaner, smarter, more resilient world.
