Good Energies Inc.

Good Energies was founded in 2001 by John A. McArthur, former chief of Lexington Partners, and Marcel van Poecke, who built and sold Atlas Energy Group. The firm's wealth originates from these two entrepreneurial careers, though neither publicly discloses personal net worth or the full capital base managed. The strategy spans direct equity, venture capital, and infrastructure-style investments focused on climate solutions. Sector preferences include renewable energy generation, energy storage, smart grid technology, and sustainable agriculture. Known portfolio companies include SolarReserve (concentrated solar power), Novomer (carbon dioxide-based materials), and EnerNOC (demand response software). Geographic focus is primarily North America and Western Europe. Good Energies maintains offices in New York and Amsterdam, with a lean team of roughly 20 investment professionals. The firm also operates a philanthropic arm, Good Energies Foundation, which supports environmental conservation and renewable energy research. In 2023, Good Energies co-invested alongside Breakthrough Energy Ventures in a Series C round for a carbon-removal startup. Good Energies operates with a hybrid mandate: it invests both its own capital and capital from select institutional co-investors, functioning partly as a direct investment fund. This structure — combining a family office ethos with a permanent capital vehicle — allows multi-decade holding periods on decarbonisation bets, rare among traditional climate funds.
