Giant Ventures

Giant Ventures is a purpose-driven, multi-stage venture capital firm founded in 2019 by Cameron McLain and Tommy Stadlen. The firm believes the biggest companies of the century will be built solving the world's most pressing problems, and champions ambitious, technical founders using technology to reshape civilization across three core themes: Climate, Health, and Inclusive Capitalism. Giant operates as a 'data-first VC,' integrating AI-driven scouting tools and proprietary pipelines to identify early signals of promising startups, while also building companies in-house alongside well-known founders. In early 2024, Giant closed two new vehicles totalling $250 million — a $100 million Seed II fund targeting ~25 early-stage companies, and a $150 million Climate Growth Fund designed to bridge the critical Series B funding gap for scaling climate tech champions. The firm invests from Pre-Seed through Growth stage across Europe and the US, with offices in London, Los Angeles, and Copenhagen. As former founders themselves, the partners emphasize empathy, hands-on support, and a strong preference for serial entrepreneurs with proven track records.
