- Bolt Projects Holdings, Inc. (Nasdaq: BSLKW) develops and produces innovative biomaterials for the beauty and personal care industry, leveraging biotechnology platforms inspired by nature to create sustainable alternatives to petroleum-based polymers and silicone elastomers. The company offers flagship products from its Vegan Silk Technology Platform, including b-silk, a fully biodegradable, non-toxic, vegan protein polymer used in haircare, skincare, and color cosmetics; and xl-silk, a silicone replacement for high-performance formulations; both manufactured at scale using renewable inputs such as yeast, water, sugar, and salt. Founded in 2009 and headquartered in San Francisco, California, Bolt Projects Holdings operates primarily in the United States, targeting global beauty brands seeking efficacious, environmentally friendly ingredients with an intellectual property portfolio comprising 62 granted patents and 173 pending applications.
In recent developments, the company completed a business combination with Golden Arrow Merger Corp in August 2024, transitioning Bolt Threads into the publicly traded Bolt Projects Holdings, Inc. and listing its common stock and warrants on Nasdaq under BSLK and BSLKW, respectively, supported by PIPE investments from investors including Baillie Gifford, Temasek, and Founders Fund. In September 2025, Bolt secured a $20 million equity purchase agreement with Ascent Partners Fund LLC to fund working capital and general corporate purposes. Additional customer launches incorporating b-silk are underway, including haircare extensions with Vegamour since 2020 and anticipated color cosmetics debuts in early 2025, driving revenue growth to $3.4 million in 2023 and positioning the company to capitalize on regulatory shifts away from silicones.
