IZB alumnus AMSilk GmbH, a world leader in supplying innovative high-performance bio-based silk materials, announced beginning of April that it has successfully raised an additional EUR 25 million in an extended Series C financing led by existing investor ATHOS (AT Newtec) with participation from Novo Holdings, Cargill, and MIG Capital.

AMSilk’s outstanding technology platform, based on silk proteins, produces bio-fabricated materials that can be utilized across a variety of applications such as textile fibers, medical devices and consumer goods.

Proceeds from the financing will enable AMSilk to accelerate the ongoing scale-up of its industrialization and commercialization projects worldwide, to meet the ever-increasing demand for AMSilk’s innovative materials.

AMSilk’s unique bio-fabrication reprograms microorganisms to enable them to produce silk proteins into usable forms such as powders, hydrogels, fibers, and coatings.  Coupled with its unique fermentation process, this allows the Company to produce complex proteins in large quantities for various market segments including textiles, medical use or consumer goods. AMSilk’s bio-fabricated silk materials are 100% protein, fully biodegradable and do not include any source of micro plastics.
