Too often, symptoms are dismissed. Answers come too late. There is simply too much guesswork. We’re here to change that - bringing clarity, support, and trust, especially when life feels the fullest.
Our co-founder and CEO Cecilia Tse was dismissed as a teen while asking about her period. That sparked a mission to give women both data and solutions, not just assumptions and sweeping generalizations.
For our co-founder and Chief Medical Officer, Dr. Thara Vayali, ND, she supported hundreds of women asking questions about stress, hormonal shifts, and preventable gaps in care. It was time to combine her clinical experience with technology to offer care to those who couldn’t otherwise find it.
Together, they built Hey Freya to help women understand their bodies, take control, and feel confident in their health decisions.
We’re starting with delivering complete cortisol care, because cortisol is often the culprit behind your actual top health concerns.
We are so happy you’re here.
