About Cofertility
Cofertility runs an egg freezing and egg donation platform that works with fertility clinics across the U.S. In its Split program, members freeze their eggs for free when they also donate eggs to a family that cannot otherwise conceive. In its Keep program, members pay to freeze their eggs and keep every egg retrieved.
Cofertility, whose legal name is EggCo, Inc., is based in Los Angeles. It was co-founded by Lauren Makler, its CEO, and Halle Tecco, its chair. Cofertility works with hundreds of partner clinics. Since October 2026, its frozen egg donation program has been part of the Progyny fertility benefits network.

Why Investors Backed Cofertility
Investors backed Cofertility for a new way to pay for egg freezing. Women in its Split program freeze their eggs for free when they donate eggs to a family that cannot conceive otherwise, so both sides gain. Cofertility works with hundreds of clinics. In October 2026, its frozen egg program joined the network of Progyny, a fertility benefits company. Next Ventures and Offline Ventures led its Series A in April 2025.
The problem it targets
Egg freezing is expensive, and its cost has been rising, CBS News reported in 2024. "The best time to freeze your eggs is when you are young, and frankly, when you can least afford it," co-founder Lauren Makler told Vogue. Cofertility also says the usual donor market ties donor pay to subjective and often problematic criteria.
What the product does
In the Split program, eligible members freeze their eggs at no cost when they donate eggs to another family. In the Keep program, members pay to freeze their eggs and keep every egg retrieved. Cofertility matches donors with intended parents on its own software and works through partner clinics. Its frozen egg program is built on disclosure readiness and family limits.
Progress so far
Cofertility has hundreds of partner clinics across the United States. In October 2026 its frozen egg donation program joined Progyny's network, so Progyny members with frozen donor egg coverage can now use that benefit for a Cofertility match. The company has not published member or revenue figures.
Who backs it
Initialized Capital and Offline Ventures led a $5 million seed round in October 2022. Next Ventures and Offline Ventures then led the Series A in April 2025, which TechCrunch put at $7.25 million, with Initialized, Arkitekt Ventures, Foreground Capital and Gaingels among the others. Tennis champion Maria Sharapova also invested, Vogue reported in 2024. Parul Singh, a former partner at Initialized Capital, sits on the board.
