About
Free Radical Ventures is a Denver-area seed-stage venture firm founded in 2013 by Principal Jim Thorson, a Colorado School of Mines geophysical engineer and former founding partner of Pronghorn Operating. The firm provides seed funding, hands-on guidance, and industry connections to hard tech, deep tech, energy tech, and clean tech startups, helping companies bridge the gap between formation and Series A. Free Radical is closely tied to the Denver Energy Tech Showcase ecosystem. Notable portfolio investments include cQuant.io (acquired April 2025), Ambyint, Well Data Labs, and Horne Technologies.
