Our mission

decarbonize cement and accelerate the clean industrial revolution

Brimstone was born from a mission to decarbonize one of the most produced materials on the planet: cement.

Our founders, Cody Finke and Hugo Leandri, met at Caltech, where they began working on solutions to some of the world’s most overlooked environmental problems. The cement industry has long been considered one of the most challenging to decarbonize, with most emissions coming from its main ingredient, limestone. ​

Cody and Hugo believed that to decarbonize cement, their product would need to be chemically and physically identical to the ordinary portland cement that builders everywhere know and trust. The process would need to be extremely low-carbon and cost-competitive at scale. ​The Brimstone team developed a breakthrough decarbonized process that produces the same cement and supplementary cementitious materials used today. These materials have the same quality and performance builders have used for decades, but with a key difference: our process doesn’t contribute to climate change.

Now, we're focused on scaling our solution—and transforming cement from climate problem to climate hero.
