Heidi Davis and Donal O'Gorman, founders of Peri, are scientists turned entrepreneurs united by a mission to transform women’s health. Their journey began with a simple but powerful realisation: the symptoms women experience in perimenopause aren’t just daily frustrations — they’re also early indicators of long-term health risks. Yet, for too long, there’s been a data gap — a lack of real, objective insight into what women’s bodies are going through. Donal and Heidi set out to fill that gap.

Peri, your body, decoded.

Peri was created to give women clarity through data — translating complex physiological signals into meaningful insights that help women understand their bodies, manage symptoms with confidence, and protect their long-term health. It’s about turning uncertainty into understanding and helping women stay healthier and more productive for longer.
