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.
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.
