Full Time

ByHeart is an infant nutrition company built from the ground up to deliver real innovation on behalf of babies and parents. Our mission is simple: make the best formula in the world. That’s why we studied the latest breast milk science, worked directly with suppliers we know and trust, set uncompromising quality standards, developed our own small batch blending process, built our own manufacturing facilities, and conducted a groundbreaking clinical trial. Our goal is to create a future where all parents feel amazing about feeding their baby—no matter how they do it.

When we launched our Whole Nutrition Infant Formula in March 2022, we were the first new U.S infant formula manufacturer in 15 years. Since then, we’ve been leading the way in a lot of ways.

We’Re…

  • The only U.S.-made infant formula to use organic, grass-fed whole milk
  • The first and only U.S. infant formula company to add the two most abundant proteins found in breast milk—alpha-lac and lactoferrin—to our ingredients list
  • The first infant formula company to receive Clean Label Project’s Purity Award (and we test for 700 contaminants vs the required 400)
  • We ran the largest clinical trial by a new infant formula brand in 25 years—clinically proving our benefits vs a leading infant formula like:
    • Less spit up
    • Softer poops
    • Easier digestion
    • More efficient weight gain
    • Enhanced nutrient absorption
    • Longer stretches between nighttime feeds*

ByHeart has rapidly emerged as a leader in infant nutrition, fortifying the domestic supply chain by owning end-to-end manufacturing in 3 US facilities and ranking in the top 10% of the U.S. infant formula category within just one year. Strategic partnerships with retailers like Walmart and Whole Foods have expanded access to their premium, science-backed formula, now available in over 70% of U.S. stores.

With >$400M in funding, we’re shifting the industry forward—and this is just the beginning. Help us build a future where all parents can feel amazing about feeding, by joining our growing team of >300 people that stretches across the country.

We're proud to offer competitive, family-first benefits, including but not limited to: 

  1. Health insurance for the whole family: medical, dental, & vision insurance covered 100%, with 90% coverage for your family.
  2. Flexible paid time off: plus 12+ company holidays, and 2 floating holidays to use at your discretion!
  3. 16-weeks of fully-paid parental leave and new parent support: free 1-year supply of formula, cozy feeding suites, and paid pumping time.
