ByHeart is an infant nutrition company based in New York City, founded in 2016, with manufacturing facilities in Pennsylvania. The company focuses on creating high-quality baby formula inspired by human breast milk. Co-founders Ron Belldegrun and Mia Funt established ByHeart to address the limited competition in the infant formula market. After seven years of development, they launched a formula that emphasizes comprehensive nutrition, using clinically proven benefits and clean ingredients.

In addition to its infant formula, ByHeart offers "Cluster," a digital platform that provides parents with resources and education to support feeding decisions from pregnancy through toddlerhood. The company is also committed to social impact through the OpenHearted Initiative, which aims to support families facing food insecurity by providing infant formula and nutrition education. ByHeart collaborates with healthcare professionals to enhance access to its products and promote informed choices in infant nutrition.
