Brimstone was born from a mission to decarbonize one of the world's most produced materials in the world: cement.
Our founders, Cody Finke and Hugo Leandri met at Caltech where they started working on environmental problems. After moving to the bay area, they discovered a way to make the world's first carbon negative portland cement. Now, we are focused on scaling our solution. We're on a mission to transform the cement industry from climate problem to climate hero.
