Some of the world’s wealthiest men, Bill Gates, Mark Zuckerberg, Jeff Bezos and Richard Branson, have all invested in a company hoping to soon sell lab-grown human breast milk.

Back in 2020, the investment firm Breakthrough Energy Venture announced $3.5 million in Series A funding for a company called BIOMILQ, Inc.

Gates, Zuckerberg, Bezos and Branson are all members of Breakthrough Energy Venture.

In 2021, the group invested an additional $21 million into the company.

BIOMILQ is a North Carolina business created in 2019 by cell biologist Leila Strickland.

The company is working to create “human milk” in a lab using cells taken from human breast tissue and milk from local women who are rewarded with Target gift cards.

A CNN Business article published earlier this month focusing on BIOMILQ said the “lab-grown” formula could be ready to sell to customers within three years.

According to the report, “BIOMILQ grows the cells in flasks, feeding them nutrients, and then incubates them in a bioreactor that mimics the environment in a breast. Here, the cells absorb more nutrients and secrete milk components.”
