Concrete is the most widely used material on earth after water, and we’re running out of a key ingredient. Widely used cement substitutes, known as supplementary cementitious materials (SCMs), have historically come from heavily polluting coal plants and iron blast furnaces. As those industrial processes are retired across the U.S. and Europe, SCM supply is shrinking. At the same time, global infrastructure is projected to double over the next 40 years.
SOSV portfolio company, Cocoon spoke to Axios following its $15M Series A, sharing how it’s unlocking a new, scalable source of cement substitutes, faster and more capital-efficiently than existing alternatives.
The Sereis A was led by 2150 and Brick & Mortar Ventures with participation from TVC, Wireframe Ventures, Celsius Industries, Gigascale Capital, and SOSV.
With this funding, Cocoon will deploy its first commercial demonstration facility in the U.S. and expand its team—hiring engineers, materials scientists, and commercial talent in the UK, alongside plant operators and technical staff in the U.S.
