TurtleTree is a biotech and food-tech company that makes lactoferrin - one of the rarest and most valuable proteins in cow's milk - without the cow. Using precision fermentation, its flagship ingredient LF+ recreates the bioactive milk protein at scale for use in immunity, gut health, sports nutrition and infant nutrition products. In 2025 TurtleTree became the first company in the world to win an FDA 'No Questions' GRAS letter for precision-fermented lactoferrin, clearing it to commercialize in the U.S.
Perfect Day is a Berkeley-based food-tech company that brews real dairy whey protein with microbes instead of cows. Using precision fermentation in steel tanks, it produces ProFerm - a beta-lactoglobulin identical to the protein in milk - and sells it as a B2B ingredient to food brands building animal-free ice cream, cream cheese, protein powders and beverages.
