Flo Health builds and operates a female health platform designed to support women across every stage of their reproductive lives, from a first period through to perimenopause. The platform offers AI-powered cycle and hormonal health tools alongside medically reviewed content and guidance. It has recorded 420 million downloads and serves 77 million monthly users, making it the most widely used women's health app in the world.
The product rests on two pillars: clinical rigour and privacy. Every piece of health content is reviewed by a network of more than 140 medical experts. The company treats privacy not as a compliance requirement but as a core design principle, embedded into the product from the ground up. Engineering, product, medical, and marketing teams work in close collaboration, and the organisation emphasises speed, ownership, and a high standard of craft.
Flo Health employs more than 450 people across offices in Vilnius, London, San Francisco, and Amsterdam. The team spans doctors, engineers, designers, and marketers. The company's technical work covers mobile and web product engineering, AI-powered tooling, data analytics, and the clinical oversight systems that underpin its content review process.
