Sarah Lamaison is the co-founder and CEO of Dioxycle, a Paris- and Bay Area-based climate-tech company building electrolyzers that turn industrial CO2 into ethylene and other chemicals using only water, electricity, and waste carbon. A chemist trained at Ecole Polytechnique, Cambridge, College de France, and Stanford, she turned her PhD on artificial photosynthesis into a company aiming to decarbonize one of the planet's dirtiest industries while staying cost-competitive with fossil feedstocks. She raised $17M in Series A funding led by Breakthrough Energy Ventures and Lowercarbon Capital, won the L'Oreal-UNESCO Young Talent award, and was named to Forbes 30 Under 30.
