Investment thesis

StartGreen Capital develops and manages specialized impact funds that bring together impact and investability, aiming to mobilize capital for sustainable and social transitions. It connects investors, projects, and companies around investable solutions. The firm addresses a market gap where entrepreneurs and project developers often need risk capital in relatively small amounts that institutional investors find hard to finance. It combines multiple financing approaches: project finance for capital-intensive energy and circular transitions, and venture capital for innovative, technically driven companies ready to scale. Focus areas include the energy transition, circular economy, and diversity & inclusion, helping solutions grow from potential to scale with lasting societal and financial impact.
