Hertility CEO Helen O’Neill on building a foundational model for women’s health

With over 700k women in the UK waiting for gynecological care, why is half the population still so underserved by its health system? Yes, women have historically been left out of clinical trials, but there are logistical reasons as to why, Hertility CEO Helen O’Neill tells host Amy Lewin. “ Collecting data from women on the third day of their menstrual cycle at scale is actually feasibly and technically very difficult to do.” Helen is more familiar with these difficulties than most: Hertility has built a diagnostic testing system to support women through their fertility journeys, and provides onward clinical care — from telemedicine gynecological appointments and ultrasounds to IVF and egg freezing. The result? Hertility, Helen says, can diagnose endometriosis with 98-99% confidence in eight days — the same condition which takes on average nine years to diagnose via the UK's National Health Service (NHS). In this episode of the Sifted podcast, Helen shares how she’s building a foundational model for women’s health, why Hertility “started off trying to be a baguette and has twisted itself into a pretzel for every investor” and why it’s important to demystify the “homogeneous idea of women’s health”.
