Let’s dive into how Flo was founded, how it scaled, and what startups can learn from its marketing DNA.
1. Humble Origins with a Sharp Focus
Flo Health was founded in 2015 by Belarusian entrepreneurs Dmitry Gurski and Yuri Gurski. They spotted a key gap: while many period tracking apps existed, few offered evidence-based, personalized health tracking backed by science. Flo launched with a simple proposition — a smart, AI-powered period tracker that could predict cycles and ovulation more accurately than traditional trackers.
Unlike many apps that started as general wellness tools, Flo stayed laser-focused on female health — especially reproductive and hormonal wellness — and positioned itself as a trusted companion for women through all life stages: puberty, fertility, pregnancy, and menopause.
2. Growth Fueled by Privacy and Personalization
One of Flo’s biggest early differentiators was its commitment to user privacy. In a sensitive space like reproductive health, this mattered. Even amid criticism in 2021 over data-sharing practices (which the company responded to with internal reforms), Flo worked toward gaining trust by implementing anonymous mode and refining data handling.
Flo also leaned heavily on personalized content — using machine learning to deliver cycle-specific health insights. This gave users a feeling of care and attention that was rare in generic health apps.
As more users shared their experiences and invited friends, Flo began organically scaling across markets — from the U.S. to India, Brazil, and across Europe.

3. Content and Community-First Marketing
Flo's growth wasn’t fueled by flashy ads — it was content-driven and community-centric. The app offers a daily feed of verified health articles, videos, and quizzes curated by medical experts. This positioned Flo as an educational hub, not just a tracker.
They also tapped into user-generated insights with the secret chat feature, allowing anonymous Q&A and discussions among users on sensitive health topics. This created emotional engagement and kept users coming back — a rare achievement in the app world.
Key marketing strategies:
Micro-influencers and user reviews were leveraged to build credibility, especially in niche communities.
App Store Optimization (ASO) played a huge role: Flo consistently ranks in top health app charts across regions.
Their YouTube and blog content covers taboo and under-addressed topics in women’s health, offering value where Google searches fall short.
4. Backed by Science and Brand Trust
A critical part of Flo’s credibility is its medical advisory board, which includes over 100 health professionals. Every piece of content and every product update is vetted for accuracy, which builds scientific legitimacy — a massive advantage in the highly skeptical digital health space.
Flo positioned itself as a bridge between clinical accuracy and user-friendly design, making women feel both heard and educated.
This trust opened doors to partnerships with researchers, public health bodies, and even governments for health education campaigns. The brand didn’t just grow — it became a voice of authority.
5. Funding and Global Reach
Flo Health has raised over $75 million to date, including a $50M Series B in 2021 led by VNV Global and Target Global. The funding helped:
Expand the team to over 400 professionals globally
Enhance AI capabilities for cycle prediction and personalized care
Increase presence in emerging markets like Southeast Asia and Latin America
With 200+ million installs and support in 22 languages, Flo is now one of the most downloaded health apps worldwide.
6. What Startups Can Learn from Flo

d. Word of mouth is still king: Product quality and helpful features led to organic virality, reinforced by user advocacy.
