Holland & Hart represented Brimstone, a venture-backed manufacturer which uses proprietary technology to produce the world’s only carbon-negative Ordinary Portland Cement and supplementary cementitious materials, in its $55 million Series A financing round. Brimstone will use this funding to build a pilot plant capable of making the first building-scale Ordinary Portland Cement ever made from a calcium silicate rock.

The financing round was co-led by existing investors Breakthrough Energy Ventures and DCVC, with participation from other existing investors, including Collaborative Fund and AccelR8. New investors include Amazon’s Climate Pledge Fund and Fifth Wall Climate Tech whose limited partners represent the global real estate industry. Other investors include Impact Science Ventures, S2G Ventures, Gatemore Capital Management, Osage University Partners, and SystemIQ.
