Minus Materials

Minus Materials is a company focused on innovative sustainability through the production of bioPCC, a biologically-derived precipitated calcium carbonate that serves multiple industries while addressing environmental concerns. Minus Materials is involved in the production of bioPCC, leveraging microalgae to create sustainable calcium carbonate. The company is headquartered in Boulder, US. Founded by Danielle B and Wil Srubar, it is currently led by CEO Sarah Williams.

In June 2022, Minus Materials raised seed funding from investor SOSV. Minus Materials specializes in developing and producing bioPCC, an innovative alternative to traditional calcium carbonate. Utilizing microalgae processes, the company delivers a high-performance calcium carbonate product with small particle size and high purity, suitable for industries such as personal care, nutrition, paints and coatings, and construction materials. Minus Materials generates revenue through direct sales of bioPCC to B2B clients across various sectors.

These clients typically enter contractual agreements to purchase bioPCC in bulk, ensuring consistent supply and quality tailored to their production needs, thus establishing long-term partnerships. Looking ahead, Minus Materials is focused on expanding its product offerings and market reach. The company plans to introduce new bioPCC products by the end of 2023 and expand into markets in Asia and South America by 2024. The recent seed funding raised in June 2022 will support these expansion efforts and the development of new product lines.
