Company Overview

About Flo Health

Flo Health is a women''s digital health company founded in 2015 and headquartered in London, United Kingdom. The company operates the world''s most downloaded women''s health app — Flo — which provides AI-powered period tracking, ovulation prediction, fertility insights, pregnancy monitoring, and menopause support. With over 70 million monthly active users across more than 150 countries, Flo is the category leader in femtech by user scale, surpassing competitors including Clue, Natural Cycles, and Ovia Health by a significant margin.

Business Model & Competitive Advantage

The company raised a $200M Series C in 2023 led by General Atlantic, valuing Flo at approximately $800M. Previous investors include Flint Capital and others. Flo operates a freemium model: the core app is free, with a Flo Premium subscription (approximately $13/month or $50/year) unlocking advanced AI health insights, personalized predictions, an anonymous mode (launched post-Roe v. Wade for data privacy), and access to a library of health content. The company generates the substantial majority of its revenue from subscriptions and has achieved profitability on an operating basis.

Competitive Landscape 2025–2026

Flo differentiates through scale, AI model accuracy (trained on one of the largest longitudinal menstrual health datasets in the world), and its expansion beyond cycle tracking into a comprehensive women''s health companion — covering fertility windows, pregnancy week-by-week guidance, postpartum recovery, and perimenopause and menopause symptom tracking. Post-Dobbs (2022), Flo introduced an Anonymous Mode that allows users to use the app without linking data to their identity — a product-level privacy response that generated significant press coverage and user trust. Flo has also begun partnering with health systems and employers to provide women''s health data insights at a population level.
