Flo is a fertility-focused period-tracking app that has expanded into a broader preventative women's health tool, offering curated cycle tracking, personalized health insights and real-time health alerts powered by machine learning. The app pairs core tracking features with science-backed content, expert-led courses and premium subscription offerings, while maintaining a freemium tier for basic tracking. Flo reports a global user base of around 200 million and an active subscriber base that grew 4x to 1.5 million in August 2021. The company says it is targeting a $100M annual run rate by the end of the year. Revenue is primarily subscription-based, supplemented by the freemium funnel. Flo has faced privacy scrutiny: it settled with the FTC over past data-sharing practices and has agreed to independent privacy reviews and to obtain user consent before sharing health information. Flo is an AI-driven women’s health platform that enables users to track periods and receive personalized health insights. The app includes a closed anonymous community of experts and peers and offers tailored health solutions for any stage of the reproductive cycle. Flo is available in 20 languages on iOS and Android and is used by over 10 million monthly active women. The company is led by founder and president Yuri Gurski and lists Matvey Timoshenko and Peter Skoromnyi among its advisors and early-stage investors. Flo raised $5M in Series A funding to accelerate growth. The company plans to expand its presence in the US and to partner with top medical research centers and universities to advance female health science.
