Freeze 7 Years Later: From Passion Project to Global Resource
In 2018, we were two friends — Sidonia and Jenny — working at the intersection of healthcare and marketing, trying to make sense of the egg freezing process and were researching our options in Miami. What we found was overwhelming: fertility clinics weren’t transparent about their pricing, phone tag was the norm, and it was nearly impossible to compare egg freezing clinics’ pricing apples to apples.
Fertility clinics required you to come for a several hundred dollar consultation to receive their pricing list, yet costs for the egg freezing procedure we came to learn — medication aside — are pretty standardized. Most clinics were geared toward infertility patients who were ready to have a baby now — with their websites, pamphlets and lobbies full of baby photos — far from the mindset of us, women electively freezing their eggs.
During our dotHealth days: We were on the team that launched the .health domain extension—an experience that took us around the world and showed us the power of how thoughtful marketing can create patient resources that real women use and value.
We started building Freeze to bring guidance where there was none — transforming our hours of research, spreadsheets, and scattered notes into a free tool to support women like us. We both froze our eggs in 2018 — Sidonia at a clinic she chose in Chicago, and Jenny at one in New York. Choosing different clinics in different cities showed us firsthand that every person’s needs are unique — and that making a confident choice takes research and clarity.
What began as a public Google spreadsheet helping share information that we acquired in our own search for a clinic has grown to be a leading resource used by 135,000+ women around the world, with robust data on 400+ clinics, and featured by The Today Show, BBC, 60 Minutes, The Washington Post, and The New York Times.
Today, Sidonia is a Physician Assistant, focusing on Freeze’s patient education and medical resources. While Jenny is not leading longitudinal real-world data registries, she is earning her Master of Public Health at Johns Hopkins University. Jenny oversees Freeze’s pricing data organization and analysis. Sidonia brings her clinical experience and Jenny contributes a strong background in patient advocacy, but at the end of the day, we were both patients ourselves — researching our options, selecting a clinic, and experiencing the egg freezing procedure firsthand.
Together, with the help of our incredible medical school interns, we’re constantly building new resources to help women save time and money so they can make confident, informed decisions.
