Venture capital is playing an increasingly decisive role in shaping the future of climate, deep tech, and industrial transformation.

Over the past decade, capital flowing into climate tech alone has grown from a niche category into a multi-billion-euro opportunity, with Europe emerging as one of the most active regions globally.

Yet despite this growth, early-stage funding remains one of the most critical bottlenecks, where the highest technical risk meets the greatest potential for impact.

These 18 investors speaking at HackSummit sit precisely at this intersection.

Collectively, they represent €1billion+ in assets under management, spanning the full lifecycle of company building from pre-seed to growth-stage.

Their strategies reflect a broader shift in venture, towards capital-intensive, science-driven innovation across energy, food systems, industrial decarbonisation, and advanced hardware.

Together, these speakers offer a unique window into how venture capital is evolving—and what it takes to fund and scale the technologies that will define the next decade.

Plus we’ve build a 200-strong list of GPs and Partners in European ClimateTech to know, many of whom will be at the Summit, looking for their next investment opportunity and co-investors.

We’re bringing the Climate Deep Tech Community to Lausanne, Switzerland.

100s of investors, many mentioned in this list, will be heading to the HackSummit on April 22-23, where deals will be made and new connections forged to accelerate investment and innovation into impact. Come and join them this month.
