## About Rubi Laboratories

Rubi Laboratories is a biotechnology startup based in Alameda, California, founded in 2021 by twin sisters Neeka and Leila Mashouf.

The company focuses on "symbiotic manufacturing," converting waste carbon emissions into carbon-negative biobased textiles and other high-value materials through an AI-optimized enzyme platform. With approximately 28 employees and over $24.6 million in funding, Rubi is positioned in the synthetic biology and carbon capture industries. The company's primary product is biobased cellulose textiles, specifically viscose-based yarn and fibers that are chemically identical to traditional cotton but produced with significantly lower environmental impact. Rubi's production technology uses ten times less energy and capital expenditure than conventional methods, and it features modular production units that can be deployed on-site at industrial facilities. Rubi Laboratories also provides affordable supply chain solutions for fashion retailers and waste management services for energy companies, targeting global manufacturers and retailers in the apparel, energy, and packaging sectors.
