transforming heavy industry. improving efficiency, economics, and sustainability.
BRIMSTONE IS WORKING on the most impactful solutions for the industrial sector, starting with CEMENT.
Our founders, Cody Finke and Hugo Leandri, met at Caltech, where they began working on solutions to some of the most overlooked industrial and 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, and heavy industry as a whole, they would need to produce the exact same materials that industry currently relies on in a new way. Their process would need to be extremely low carbon and cost-competitive at scale.
The Brimstone team developed the Brimstone Rock Refinery, which refines a single rock into multiple industrial products, including cement, supplementary cementitious materials (SCM), and, as we recently announced, alumina. These materials are designed to have the same quality and performance that builders and industrial customers expect, but through an efficient, economical, and sustainable process.
Now, we're focused on scaling our solution—and transforming heavy industry for a better future.

We're engineering a first-of-a-kind solution for one of the biggest climate problems, and we’re hiring an all-star team to join us.
If you’re ready to make a gigaton impact, explore our open roles.


"Industrial innovation historically follows a pattern: first develop the process, then optimize for cost through co-production as the market grows. This efficiency-driven, lower-cost approach has transformed the production of nearly all commodities, from copper to ammonia fertilizer to gasoline. Cement has been one of very few exceptions—until now. Brimstone is changing that."
