MycoWorks

MycoWorks is a biotechnology company based in Emeryville, California, founded in 2013. The company focuses on creating sustainable, high-quality leather-like materials from mycelium, the root structure of mushrooms, using its patented Fine Mycelium™ technology. This innovative approach allows MycoWorks to engineer materials that offer strength and durability comparable to traditional animal leather. The flagship product, Reishi™, is a premium natural material that replicates the softness and appearance of fine leather without using animal products or harmful tanning chemicals. Variants of Reishi include Reishi Doux, Reishi Natural, and Reishi Pebble, which are utilized in luxury fashion items such as handbags and hats. MycoWorks began commercial-scale manufacturing of these materials in September 2023 in Union, South Carolina. The company collaborates with high-end brands like Hermès and Ligne Roset, aiming to provide sustainable alternatives for the fashion, automotive, and home decor industries.
