About Us
Brimstone is on a mission to decarbonize the cement industry. The $1 trillion cement market is responsible for 7.5% of carbon emissions annually, with a greenhouse gas impact just behind cars. Founded in 2019, Brimstone developed a breakthrough carbon-negative process that produces the exact same cement and supplementary cementitious materials used today. These materials have the same quality and performance builders have trusted for over 150 years. The key difference: on net, our process takes carbon dioxide out of the air instead of putting it in.
Our team is now scaling up to refine our process further and to build our first production facilities. We’re assembling an all-star team of sharp, mission-driven, collaborative individuals who take pride in using their diverse skills to contribute to a better world. If you are interested in joining a team of builders, surfers, amateur chefs, podcast junkies, bibliophiles, dog lovers, and car campers who wake up every day excited to work on addressing climate change — we are the company for you! Want to join us in decarbonizing cement? You can help us solve the most urgent, important challenge facing the world today (and have a blast while doing it).
You Should Join Us If You:
Are passionate and motivated about our mission to fight climate change.
Have an insatiable sense of curiosity and a drive to solve problems.
Thrive in a fast-paced collaborative startup environment.
Want to work with a fun, mission-aligned, and values-oriented team
