Brimstone

Brimstone is a manufacturing startup that aims to decarbonize the cement industry, which is currently responsible for 7.5% of annual carbon emissions. Founded in 2019, the company has developed a breakthrough carbon-negative process that allows for the production of the same ordinary portland cement and supplementary cementitious materials used today without changing the product or price. This means that the materials maintain the same quality and performance that builders have trusted for decades, while also having a positive climate impact. Brimstone is based in the United States. As of now, the company has not disclosed its last investment or the investors involved. With the potential to address a significant environmental issue while maintaining the integrity of a well-established industry, Brimstone presents an intriguing opportunity for venture capital consideration.
