Spiber Inc. is a Japanese biotechnology and advanced-materials company founded in 2007 and headquartered in Tsuruoka, Yamagata Prefecture, Japan. Spiber develops Brewed Protein materials — structural proteins produced by precision fermentation of plant-derived sugars using engineered microbes, then spun into fibers, resins, and films as animal-free, petroleum-free alternatives to silk, wool, cashmere, leather, and synthetic polymers. The company operates fermentation plants in Japan, Thailand, and the United States and supplies apparel, outdoor, automotive, and consumer brands, alongside a research program in synthetic biology, polymer science, and life-cycle assessment. Spiber is a materials manufacturer rather than a software vendor and publishes no developer program, developer portal, SDKs, or product API; the only machine-readable HTTP surface it serves is the read-only WordPress REST content API behind its corporate website.
