Science and technology, in service of your health.
We started Belle as a couple at the University of Cambridge, combining medical and engineering experience to change the status quo in female health.
Our story
The problem
You need to be heard.
Women still face long, frustrating paths to diagnosis and care — too often marked by invalidation and isolation.
It is not “just in your head.”Your experience is real.
The principles
Care, with a point of view.
Power & freedom
Knowledge and tools for your own health journey.
Long-term health
Look beyond a single symptom.
Whole-person care
Mind, body, and daily life belong together.
Evidence first
Solid research. Clear decisions. No fluff.
Awareness & support
Hormonal health is real, and it matters.
Technology for care
Science and technology should make care better.
The advisors
Built with researchers.
Our scientific advisors bring clinical and behavioral-health expertise to product development and research.
Premenstrual care is deeply flawed. We started Belle to change how these conditions are understood, managed, and treated — so no one is told to simply put up with it. Not anymore.Victoria & Rafael · FoundersDiscover the Belle app
