SPIBER
Spiber Inc. (Director and Representative Executive Officer: Kazuhide Sekiyama; hereinafter “Spiber”), a biomanufacturing startup, is pleased to announce the successful completion of a round of fundraising totaling over JPY 10 billion. This funding, which includes additional investments from existing shareholders, will allow the company to accelerate mass production of its innovative Brewed Protein™ materials and facilitate global sales, further contributing to the advancement of a circular economy.
Spiber’s proprietary Brewed Protein™ material is a new category of material¹ developed and refined through more than 15 years of research. By harnessing the diverse, cyclical nature of proteins, one of the key building blocks of Earth’s ecosystem, the company aims to realize a circular economy that can exist in harmony with nature. Using cutting-edge biotechnology, Spiber’s proteins are meticulously designed at the DNA level and manufactured through a proprietary microbial fermentation process with plant-based raw ingredients. Amidst the rapidly growing need for sustainable solutions, the value and potential of Brewed Protein™ materials have been highly evaluated by investors and consumers alike, and Spiber is engaged in numerous joint projects with apparel brands and other partners. To date, 15 domestic and international brands have launched products using Spiber’s materials, and the company will continue to strengthen its production system and R&D platform to meet the expected growth in demand and diversifying needs.
1: On November 1, 2021, the International Organization for Standardization (ISO) issued a revision to the definition of “protein fibre” in ISO2076. With this revision, the term “protein fibre” now includes not only naturally-derived protein, but synthetically-produced protein as well. Furthermore, the minimum protein content required for fibres to meet this definition has now been set at 80%. With the publication of this standard, synthetic structural protein materials have for the first time been internationally recognized as a new category of material.
