Bill Ritter serves as an Operating Partner at Blackhorn Ventures, where he primarily invests in early-stage (Seed and Series A) companies within the energy, construction/built environment, and transportation sectors, focusing on software-centric solutions for industrial decarbonization. His distinctive thesis centers on "Industry 4.0," asserting that decarbonizing hard-to-abate industrial sectors requires the convergence of artificial intelligence and digital infrastructure to improve resource efficiency. While Ritter himself leverages his network in energy and policy rather than managing funds directly, Blackhorn's notable portfolio includes grid AI firm ThinkLabs, EV charging company Electric Era, and construction optioneering platform ALICE Technologies. The firm typically writes checks of $1M–$5M for Seed rounds and $8M–$15M for Series A, with a minimum check size of $500,000.
