Colorifix

Based in Norwich, UK, Colorifix is a biotechnology company that engineers microbes to produce, deposit, and fix natural pigments onto textiles using synthetic biology and fermentation. The enterprise provides its biological dyeing technology directly to commercial textile mills and dye houses, enabling them to reduce water consumption by up to 90 percent and chemical pollution by 80 percent compared to traditional methods. Operating with a workforce of approximately 100 employees, the organization ships small quantities of engineered microbes to clients who then cultivate the pigments on-site. The company has secured significant capital to scale its global operations, including an £18 million Series B in 2022 and an $18 million B2 round in 2025 backed by investors such as H&M Group, Inter IKEA Group, and Cambridge Enterprise. Colorifix was founded in 2016 by Orr Yarkoni and Jim Ajioka.
