About Us
The cement/concrete industry is a $1T market opportunity responsible for 5.5% of GHG or approximately 7.5% of global CO2 emissions. This is the same amount of emissions released by the cars we drive daily. Increased concentrations of greenhouse gasses in our atmosphere not only pose a threat to all living things on earth, but especially to disadvantaged communities. At Brimstone, we’ve taken the initiative to stop and revert the effects of climate change through the production of carbon-neutral Portland cement and supplementary cementitious materials, regardless of the energy source. 

Our mission is to eliminate industrial greenhouse gas emissions by developing technologies to help industries transition faster to net-zero. 

Brimstone was founded in 2019 at Caltech and since then moved to the Bay Area thanks to Cyclotron Road and other federal and private grants. We are lucky to be supported by wonderful investors and advisors. Over the past couple of years, we have worked to build an equitable company that we are proud of with very special individuals dedicated to this cause which gives us an immense amount of joy to work with every day. Our culture is focused on hard work, equity, and gratitude.
