A protein biochemist got tired of ingredient hunts that take 15 years. So she built a search engine for nature's proteins - and its first product is a fat that behaves like butter without the palm oil.
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.

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.
