Werewool, a New York-based provider of sustainable performance fibers, raised $3.7 million in a funding round led by Material Impact and Sofinnova Partners.

The company intends to use the funds to develop its first product, protein fibers that can be spun into yarns, add manufacturing capabilities and expand the team. The technology is co-patented between the Fashion Institute of Technology (FIT) and Columbia University.

“Our mission as a company is to make the fashion industry compatible with nature,” said Chui-Lian Lee, co-founder and CEO of Werewool. “Our team looks at the textile industry holistically considering the end of life at the beginning of life – our goal is for our fibres to decompose into nutrients for a healthier ecosystem. We are excited to be growing and are looking to fill key leadership roles in the company with people who can contribute to our team’s vision for a truly circular textile economy.”

“At Material Impact, we seek out deep tech innovation that has the capacity to solve enduring, large-scale, real-world problems,” said Corinna Chen, partner at Material Impact. “Werewool’s revolutionary fiber development platform offers the textile industry a breakthrough approach to sustainable and functional textiles.”
