Modern Synthesis raises $5.5M to grow microbial biomaterials
London-based biotechnology firm Modern Synthesis has successfully raised $5.5 million in an oversubscribed funding round, led by Extantia Capital, with additional backing from Artesian and Collaborative Fund. The funds will support the scaling of its pilot facility and help meet the growing demand for sustainable material alternatives in the fashion industry.
Modern Synthesis develops innovative biomaterials using nanocellulose, a fiber derived from microbial fermentation. The company’s proprietary process creates durable, plastic-free alternatives to traditional leathers, synthetic leather, and plastic-coated textiles. Nanocellulose’s strength at the nanofiber level—stronger than steel—ensures the resulting materials offer superior performance without compromising on look or feel. This positions Modern Synthesis to help brands seeking sustainable solutions in the face of tightening regulations aimed at decarbonization.
As fashion faces a projected shortage of 133 million tonnes of low-impact raw materials by 2030, Modern Synthesis’ technology presents a solution to mitigate this gap. CEO Jen Keane emphasized that their material offers an exciting, sustainable alternative that can captivate consumers while also promoting circularity in the fashion industry.
The company has already attracted attention through its collaboration with Danish fashion brand GANNI, working toward the commercial launch of the Bou Bag, made from Modern Synthesis’ biomaterial. Despite the growing interest in sustainable textiles, they currently represent less than 5% of the $1 trillion global apparel textile market.
Investor confidence is strong, with Extantia Capital’s Yair Reem noting that Modern Synthesis’ material not only rivals traditional leather in appearance and feel but also offers something new and innovative that excites designers. This funding will enable the company to expand its material offerings into other industries, including footwear and automotive sectors.
As more than 35 new sustainability regulations are expected to reshape the textile industry, brands that fail to adapt to lower-impact materials could face significant financial consequences. The growing market potential for biomaterials underscores Modern Synthesis’ role as a key player in the sustainable materials movement.
