Munich, 4 April 2023

MIG Capital, one of Germany’s leading venture capital firms, announced today the closing of an extended Series C financing for its portfolio company AMSilk GmbH, the world’s first industrial supplier of biotechnologically produced silk proteins. AMSilk raised an additional € 25 million in a funding round led by existing investor ATHOS (AT Newtec) with participation from Novo Holdings, Cargill, and MIG Capital via its MIG funds, including the latest MIG fund No. 17. This additional capital increases the total volume of the Series C round to € 54 million. 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 platform 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.

Ulrich Scherbel, Chief Executive Officer of AMSilk, says: “We are delighted to have closed this successful financing round which validates our technology and underpins our ongoing development as we scale-up and expand our commercial operations. We will invest in technology to ensure that we continue to provide innovative, attractive solutions to our customers, and improve the commercial supply of our products to expand our business.”

Michael Motschmann, Managing Partner of MIG Capital, adds: “This financing will allow AMSilk to quickly tackle its ambitious agenda. Specifically, supply commitments with leading global consumer brands will be pursued with the aim of converting them into supply agreements. In addition, the commercial production of biotech silk proteins on a multi-ton scale will be started, and the construction of the first plant for protein production specifically designed for AMSilk at a well-known customer site will be initiated.”
