Investment thesis
Overture is an early-stage venture fund focused on startups in energy, artificial intelligence, resilience, and industrial transformation. Its differentiated edge is helping founders win government support and navigate regulatory complexity, positioning the firm as a bridge between startups and governments. Each portfolio company receives in-kind support from Boundary Stone Partners, a climate-focused government affairs firm founded by the team, to help unlock federal, state, and municipal government opportunities. The team draws on experience as senior political appointees at the U.S. Department of Energy and the White House, as government-affairs builders at companies like Airbnb, and as investors and founders with prior deployments and exits.
