Company Description

ByHeart is an infant nutrition company that researches, develops, manufactures, and markets its own infant formula. Founded in 2016 by Ron Belldegrun and Mia Funt, the New York-based company launched its Whole Nutrition Infant Formula in March 2022, becoming the first new U.S. infant formula manufacturer in 15 years. The company operates its own manufacturing facilities and uses organic, grass-fed whole milk in its formula. It is the first U.S. formula company to add alpha-lac and lactoferrin, two abundant proteins found in breast milk, and has received the Clean Label Project’s Purity Award after testing for 700 contaminants.

Looking forward, ByHeart is expanding its retail presence, including a recent launch at Sam's Club, and is involved in industry advocacy through government initiatives like "Operation Stork Speed" to modernize formula standards. The company also offers parent support services, such as a 24/7 hotline. In June 2024, ByHeart closed a $95 million Series C funding round, increasing its total funding to over $250 million to support continued growth and innovation.
