Baillie GiffordCCool Japan FundKKeio UniversitySpiber develops structural protein technology it markets as Brewed Protein fiber, supplying material for apparel, lifestyle, beauty, food and healthcare uses. Shiseido has used Brewed Protein fiber to develop a cosmetic ingredient for mascara, and the material has appeared in outdoor apparel collaborations such as The North Face's CORDE line and pieces with Goldwin. Spiber has spent more than 15 years developing protein materials since it was founded in 2007, and the company is based in Japan.
Spiber produces its material in small quantities at a plant in Japan, which is one reason early North Face products made with the fiber carried a premium price.
