Cofertility Just Raised $7.25M to Reimagine Egg Freezing—and It’s Only the Beginning
Cofertility is a human-first fertility ecosystem rewriting the egg freezing and egg donation experience.
What if freezing your eggs didn’t come with a $15,000 price tag? What if helping someone else build their family could also help you plan your own? That’s the model behind Cofertility, a women’s health startup that just raised a $7.25 million Series A to expand its radical and refreshingly human approach to fertility care.
Founded by Lauren Makler (a former Uber exec) and Halle Tecco (a health tech investor and founder of Natalist), Cofertility offers a no-cost egg freezing option for women who donate half of their retrieved eggs to intended parents struggling with infertility. The company’s “Split” program flips the traditional donation model on its head—making egg preservation more accessible and donation less transactional.
As Makler wrote in her LinkedIn post, “We started with a mission: to make egg freezing more accessible, egg donation less transactional, and fertility care more equitable, transparent, and human-centered.”
The Series A round was co-led by Offline Ventures and Next Ventures (which includes Melanie Strong and Lance Armstrong), with participation from Initialized, Gaingels, Gratitude Railroad, Everywhere Ventures, and more. With this new capital, Cofertility’s total funding reaches $16 million.
From Personal Health Scare to Industry Shift
Makler’s path to founding Cofertility was personal. A rare health diagnosis in 2018 left her facing potential fertility loss, and the experience exposed major gaps in the egg donation system—especially for women who wanted to preserve their fertility while also helping others.
As she shared with TechCrunch, she was shocked by how egg pricing worked, especially when it came to attributes like religion, education, or ethnicity. “It felt sort of like surge pricing for egg donors,” she said—an echo of the ride-hailing world she once worked in.
Cofertility aims to offer a more transparent, values-aligned alternative. In its model, intended parents cover the retrieval costs and Cofertility’s fee, but there’s no donor compensation beyond the egg freezing itself. That makes the process less commodified and more collaborative.
Makler is quick to note that while the concept of egg sharing isn’t new, Cofertility is the only company scaling it—with hundreds of donors available at any time. In contrast, most fertility clinics only have a handful, making it tough to find a match.
And it’s not just about scale—it’s about diversity and quality. Cofertility says over half of its donors have graduate degrees and come from a wide range of backgrounds, offering more inclusive family-building options for intended parents.
More Than a Fundraise—A Movement
Makler emphasized that this isn’t just a milestone for the company—it’s a moment for the families they’ve helped. “I’ve always believed that a fundraise shouldn’t be a celebration in itself,” she wrote. “So while I am so proud to share this milestone, I’m even prouder of the families we’ve helped build on the way here.”
With the Series A, Cofertility plans to expand its technology, grow its team, and deepen its work in normalizing egg donation and preservation. As Makler put it, “We’re just getting started.” And if the last three years are any indication, what they’re building isn’t just a platform—it’s a new paradigm for how women navigate fertility on their own terms.
