Flo Health has built a 350-million-user empire by talking about what everyone else avoids.
While competitors stuck to polished, sanitized content about "wellness," Flo created an entire movement around the raw, uncomfortable, universally-ignored realities of female health.
Here's how they did it.
The Problem: Female Health Is Underrepresented and Misunderstood
For decades, women's health has been either medicalized beyond recognition or romanticized into meaninglessness.
The is what Flo recognized:
Women don't need another app telling them to "practice self-care" or "listen to their bodies." They need actual information about what's happening to them, information that's been systematically excluded from public conversation.
- Period pain is dismissed as "just cramps" when it can be debilitating
- Hormonal imbalances go undiagnosed for years because women are told it's "normal"
- Fertility and conception remain shrouded in myths and misinformation
- Sexual health is either taboo or framed through a male lens
Turn Silence Into Conversation
Flo's approach wasn't just to build a tracking app. It was to create the most honest, comprehensive, unapologetic platform for female health education.
They spoke the way women actually talk to each other:
- "Why does my period make me want to fight everyone?"
- "The hormone drop before your period explained"
- "Things nobody tells you about ovulation"
- "Why you're crying for no reason (spoiler: hormones)"
The content pillars:
Education Without Judgment
Breaking down complex hormonal cycles, fertility windows, and symptoms in accessible language.
Universal Struggles
Showcasing the experiences every woman recognizes but rarely sees acknowledged publicly: the period pain, the mood swings, the confusion around "normal" vs. "get this checked."
Taboo Topics Normalized
Sex advice. Fertility concerns. Hormonal acne. Weight fluctuations. Libido changes. Everything that's been whispered about in private, brought into open conversation.
Community Validation
"You're not alone" messaging backed by data, science, and millions of women sharing similar experiences.
Flo partnered with House of Marketers to execute a TikTok influencer strategy designed for maximum engagement and authentic representation.
Influencer Marketing That Felt Like Sisterhood
Flo found credible voices women already trusted for health advice:
Healthcare Professionals
OB-GYNs, nurses, and health educators breaking down women's health topics in accessible ways. When medical professionals endorsed Flo, it removed all skepticism.
Relatable Lifestyle Creators
Women documenting their real experiences with periods, hormones, fertility journeys, and health struggles.
Community Leaders
Creators who'd already built trust by discussing taboo topics openly. Women who made their audiences feel seen and less alone.
The Affiliate Program: Turning Users Into Advocates
Flo built a sustainable affiliate ecosystem that turned satisfied users into brand ambassadors.
The affiliate value proposition:

The genius move: By making the program accessible globally and emphasizing the mission over the money, Flo attracted affiliates who genuinely believed in improving women's health access.
Multi-Platform Presence
While TikTok drove massive engagement, Flo maintained strategic presence across:
Instagram: Longer-form educational content, community features, expert Q&As
YouTube: Deep dives into health topics, creator partnerships, documentary-style content
Pinterest: Symptom guides, cycle-tracking tips, visual health education
Blog/Website: SEO-optimized long-form content answering common questions
Each platform served a purpose in the funnel:
- TikTok/Reels: Awareness and viral engagement
- Instagram/YouTube: Education and community building
- Pinterest/Blog: SEO and evergreen conversion content
Impact
Flo's strategy delivered measurable business results that extended far beyond marketing metrics.
Growth Metrics:
- 350M+ global users (and counting)
- #1 OB-GYN-recommended period tracking app in the US
- 200K+ engagements from House of Marketers TikTok campaign alone

The lesson for other brands:
If your product genuinely improves lives, lead with that impact. Don't hide behind features and benefits. Show people you understand their struggle, educate them on why it happens, and position your product as the natural solution..
