Profile

Spiber is a Japanese biotechnology company founded in 2007 and headquartered in Tsuruoka, Yamagata Prefecture. It specializes in the development of Brewed Protein, a proprietary, lab-grown structural protein material created through microbial fermentation using plant-based sugars. These materials are designed at the DNA level to serve as sustainable, biodegradable alternatives to animal-derived fibers like cashmere and wool, as well as synthetic plastics.

As of April 1, 2026, the company operates under a new management structure led by CEO Maya Kawana, with founders Kazuhide Sekiyama and Junichi Sugahara transitioning to focus on technical development and commercialization. The company maintains production facilities in Tsuruoka, Japan, and Rayong, Thailand. It has raised over $640 million in total funding to scale production and expand into lifestyle, beauty, food, and healthcare markets.

Spiber collaborates with over 80 textile manufacturers and has partnered with brands including The North Face, Goldwin, Stella McCartney, and Issey Miyake. The company is actively pursuing early monetization and the social implementation of its materials, including ongoing efforts to utilize agricultural waste as feedstock.
