CO2-to-materials start-up Rubi secures new funds
Rubi, a textile tech start-up based in San Francisco, has developed a process using enzymes that converts carbon into textile fibres. Nearing industrial demonstration, the company has attracted new funding, of $7.5 million, from a group of investors that includes H&M Group. The new resources will allow the company to move on to industrial demonstration level, advance its enzyme engineering processes, and explore additional pipeline products, beyond fibres, in consumer goods and aeronautics. 

In 2025, Rubi said that it had signed multi-year offtake term sheets worth over $60 million with commercial partners that now number 15, up from seven, and include Walmart and Reformation.

The company founded by twins Neeka Mashouf and Dr. Leila Mashouf in 2021, has developed a process that uses enzymes to transform carbon molecules, such as carbon dioxide, into cellulose polymers. It claims that its platform requires significantly less capital than other fermentation-based methods and could be deployed in modular units anywhere.
