Helios Climate Ventures is a small, specialized venture capital fund focused exclusively on energy storage technologies like batteries, anodes, and grid storage, operating from Aspen, Colorado with a team of roughly 6 people who combine technical, policy, and financial expertise. The fund backs technically demanding hardware companies that many generalist VCs avoid and consistently co-invests alongside major industrials like Mercedes-Benz, Hyundai, and Chevron, positioning itself as a well-networked specialist that can help connect portfolio companies to large manufacturers for later-stage scaling.
