Standish Spring Investments: Early-stage firm led by Steve Bolze and Brian Bolze, concentrated on hard-tech decarbonization from Duxbury, MA.
Standish Spring Investments
Standish Spring Investments is led by Steve Bolze and Brian Bolze. The firm focuses on early-stage companies, investing in founders across energy transition, advanced air mobility, life sciences, and enterprise software. The firm's portfolio is anchored in deep decarbonization technologies. Confirmed positions include Commonwealth Fusion Systems, which is building the world's first commercial nuclear fusion power plant; Blue Energy, which develops advanced modular nuclear reactor technology; and Beta Technologies, an electric vertical takeoff and landing aircraft manufacturer. The portfolio spans solar energy storage with companies like Euclid, clean hydrogen production with Evoloh, and sustainable mining technology with Phoenix Tailings. Geographically, the firm invests primarily in the United States. Standish Spring lists over 20 active portfolio companies on its website but discloses no AUM or total deployment figures. The firm does not maintain a LinkedIn presence or publish details on team size. There is no public information regarding additional offices, adjacent investment vehicles, or philanthropic structures. Investing almost exclusively in hard-tech climate and industrial transformation, Standish Spring operates with an unusually concentrated thesis for an early-stage firm — bypassing broader venture mandates in favor of a narrow wager on the physical infrastructure of the energy transition.
