Equatic
Equatic is a Carbon Removal (CDR) company founded in 2021 and based in Los Angeles, United States. It has raised $11.6M in total funding, most recently a Series A in 2025.
Equatic is a UCLA spinout founded in 2021 and based in Los Angeles, commercializing a seawater-electrolysis process invented by co-founders Xin Chen and Gaurav Sant. The technology accelerates the ocean's natural carbon uptake, trapping CO2 as solid carbonate minerals and dissolved bicarbonate for durable storage, while producing carbon-negative green hydrogen as a co-product. The company unveiled oxygen-selective anodes to improve efficiency at scale, and in August 2025 closed an $11.6 million Series A led by Catalytic Capital for Climate and Health, a vehicle of Temasek Trust, and Singapore-based Kibo Invest.
It pairs durable ocean-based carbon removal with green-hydrogen revenue, a dual-output model few CDR companies can claim.
