Japan
Spiber株式会社, founded in 2007 and headquartered in Japan, is a pioneering bioventure specializing in the development and production of structural proteins known as Brewed Protein™素材. Driven by their slogan, "More than materials.", Spiber is dedicated to contributing to sustainable well-being through novel solutions.
The company has engineered an innovative process where plant-derived raw materials are molecularly engineered into proteins, produced through a unique microbial fermentation process. This versatility enables applications across various industries such as biotechnology, apparel, food, automotive, and more, unlocking new possibilities for sustainable and high-performance materials.
In a bid to enhance global footprint, Spiber launched its first mass-production plant in Thailand in 2022. The plant leverages increased production capabilities, supplying fiber-processed materials to brands, textile manufacturers, and trading companies worldwide. Supported by a substantial $314 million Late VC investment in May 2025 from investors including The Carlyle Group and Cool Japan Fund, Spiber is well-positioned for scalable growth and broadening market reach.
