Terraton

Terraton is a San Francisco climate-tech company that turns agricultural waste into biochar - a stable, carbon-rich material that locks away CO2 for centuries. It packages financing, hardware, and software into a 'biochar business in a box' so agribusinesses in emerging markets can launch carbon-removal facilities, while corporate buyers get verified, high-durability carbon credits delivered at scale. Backed by an $11.5M seed round co-led by Lowercarbon Capital and Gigascale Capital, Terraton already runs facilities in Ghana and Kenya.
