Rooftop Recharge @ London Climate Action Week

Join ArcTern Ventures, Clean Energy Ventures, Energy Revolution Ventures,  InnoEnergy, and Prosemino for an afternoon with founders from across our portfolios.
We've invited a group of climate tech companies working on everything from industrial decarbonization and energy systems to manufacturing and infrastructure. The idea is simple: bring together founders, investors, and industry partners for a few hours of conversation in one room.
No panels. No fireside chats. Just time to meet the companies, hear what they're working on, and connect with others across the climate tech ecosystem.
We'll be gathering at York Road Spaces & Stories in Waterloo, with lunch, refreshments, and access to the rooftop terrace throughout the event.
