ZeroEx is scaling permanent carbon removal through enhanced rock weathering (ERW) projects in Germany, Brazil, and the United States. We license cutting-edge measurement tech that verifies every tonne sequestered, opening up the ERW industry to mining and agribusinesses ready to add an additional business model or decarbonize their core business.

Culture is the shadow of people—self-guided missiles who run on trust, ownership, and speed. If you thrive in ambiguity, lead from any seat, and care deeply about climate impact, you’ll feel at home here.
