Climate Capital

Climate Capital is a San Francisco-based pre-seed and seed venture capital firm focused on climate technology, backing early-stage companies developing breakthrough solutions to the climate crisis across clean energy, carbon removal, sustainable food and agriculture, industrial decarbonization, and circular economy sectors. The firm invests at the earliest stages of company formation with initial checks from $1 million to $5 million, often leading or co-leading rounds before most institutional climate capital enters. Climate Capital brings deep sector expertise in climate science, energy systems, and technology commercialization to help founders navigate the specific challenges of climate deep tech. Portfolio companies include Ampere Industrial Energy, a battery energy storage systems company; Antora Energy, the thermal energy storage company; Climeworks, the Swiss direct air capture company that operates commercial CO2 removal plants; and Xpansiv, the marketplace for trading environmental commodities including carbon credits, renewable energy certificates, and sustainable aviation fuel. Beyond its original investments in Ampere, Antora, Climeworks, and Xpansiv, the portfolio includes additional climate technology companies at the earliest stages of development.
