Fengru Lin is the co-founder and CEO of TurtleTree, a biotech company making dairy proteins without cows. A former Google account manager who took up cheesemaking as a hobby, she went hunting across Asia for clean raw milk, was horrified by what she found on the farms, and started a company to make milk in a lab instead. TurtleTree pivoted from full cell-cultured milk to precision fermentation, and now produces lactoferrin, a high-value milk protein once called 'pink gold,' using microbes instead of herds. She has raised roughly $44 million and made EDGE's 35 Under 35 and Her World's Young Woman Achiever lists.
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.
Ryan Pandya co-founded Perfect Day in 2014 with the audacious goal of making dairy without cows. Using precision fermentation, the Berkeley-based biotech raised nearly $800 million, built partnerships with Fortune 500 food companies, and proved that animal-free whey protein could reach global markets across dozens of product categories. After a decade at the helm, Pandya stepped down as CEO at the end of 2023 to pursue future ventures, leaving behind a company that had fundamentally shifted the conversation around sustainable dairy.
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.
