Alpine Bio develops functional proteins and bioactive ingredients for food, nutrition, and health applications using molecular farming and advanced purification technologies. The company expresses target proteins directly in soybeans, converting plants into production systems that replace fermentation infrastructure and animal agriculture. Alpine Bio's first commercial ingredient is casein, a dairy protein used in cheese production, which the company has produced through its plant-based platform and plans to commercialize under the Nobell Foods brand. The company was founded in 2016 and is based in South San Francisco, California. Alpine Bio has raised $100 million in total funding, with its most recent Series B round of $75 million completed approximately four years ago; investors include Andreessen Horowitz, Breakthrough Energy, Footprint Coalition, and Mission BioCapital. The company has filed over 40 patents related to plant-based protein production and has expressed more than 15 complex proteins in plants.
