BERLIN, May 22, 2025 — Clue, the women’s health platform driven by data, revealed today that it has reached 1 million paying subscribers, more than doubling its user base in just over a year. This achievement coincides with rapid expansion in the digital menstrual health market, which is expected to grow from €1.2 billion in 2024 to €9.3 billion by 2030 — an 8x increase in only six years.

As consumers increasingly adopt digital solutions for proactive health management, women are using technology to gain insights into their reproductive health. Recent studies indicate that 78% of women experience cycle-related symptoms affecting their quality of life, often inadequately addressed by traditional healthcare.

“Reaching one million paid subscribers is more than just a business milestone,” said Rhiannon White, CEO of Clue. “It validates our mission to provide women everywhere with personalized, science-backed health information that empowers them to understand their bodies with confidence. Our subscribers are using Clue not just to track periods, but to gain insights throughout their reproductive journey.”

Scientific Foundation and Regulatory Excellence Drive Trust

Clue’s success is built on its strong commitment to scientific accuracy, medical precision, and data privacy. The company adheres to the highest medical standards with CE-licensed products for conception and FDA compliance, which ensures both user trust and clinical validity. This regulatory excellence has allowed Clue to build one of the largest reproductive health datasets globally.

Clue’s extensive longitudinal dataset includes over 25 billion health data points, analysis of 750 million cycles, and 3.2 million confirmed diagnoses. Protected by strict GDPR privacy measures, this rich data foundation has earned the trust of over 10 million women worldwide who confidently share their most sensitive health information with the platform.

Powerful Technology and Data Create Superior User Experience

By combining this vast dataset with its technology, Clue delivers personalized reproductive lifecycle analytics that adapt to each user’s patterns over time. These analytics provide deep cycle insights, conception predictions, pregnancy tracking, and perimenopause support – comprehensive insights that evolve with women through every life stage.

This data-centric approach has resulted in high user satisfaction, with Clue receiving a 4.8-star rating from over 2.5 million reviews. The app’s subscriber retention rates are well above industry averages, with 81% of users reporting that Clue helps them feel more prepared for symptoms, and 72% saying it gives them greater control over their health.

“Our users consistently share that Clue offers insights they can’t find elsewhere,” said White. “They’re not just tracking their periods; they’re understanding patterns in their energy levels, sleep quality, mood, and physical symptoms that impact their daily lives. This comprehensive understanding fosters loyalty, directly contributing to subscription longevity.”

Strategic Marketing and Partnerships Drive Acquisition

Clue’s subscriber growth has been boosted by the arrival of Chief Marketing Officer Louise Troen, who joined in February 2024 and has transformed the company’s user acquisition strategy.

“We’ve greatly improved our approach to both paid and organic user acquisition,” said Troen. “By optimizing data-driven campaigns on leading social media platforms, along with app store optimization, we can precisely target high-conversion prospects — especially digitally active women dealing with conception, contraception, or other cycle-related issues.”

The data highlights interesting demographic trends among Clue’s users. While the free app appeals to a wide age range, paying subscribers tend to be women in their 30s looking for more detailed health insights. Many of Clue’s younger users in their 20s, who initially join as free users, eventually upgrade to paid subscriptions as they get older and their health needs change.

Meanwhile, Clue’s B2B2C partnerships have opened up additional acquisition channels that bring in new subscribers at a lower cost than traditional marketing, resulting in a 50% improvement in the LTV/CAC ratio in the past year. These strategic alliances with related wellness brands, healthcare providers, and employers not only increase Clue’s reach but also attract users who are more likely to appreciate premium features.

Accelerated Growth and Commercial Success

The combination of a trustworthy scientific foundation, excellent user experience, and strategic marketing has led to significant business results. Clue’s conversion rate from free to paid users has increased from 3.7% in early 2023 to 9.3% today, reflecting the increasing value users find in Clue’s premium offerings.

“This growth in conversion efficiency, along with our expanding user base, has been critical in our journey from 500,000 subscribers in May 2024 to the 1 million milestone we’re celebrating today,” said Balint Veres, Clue’s CFO.

Looking Ahead

As Clue continues to grow its subscriber base, the company is focused on further improving its technology and developing new features to address the full range of women’s health needs. With users in over 190 countries and 10 million monthly active users worldwide, Clue has established a truly global presence, with most of its paid subscribers currently in North America and Europe.

“Our next growth phase will build on our success in these core markets while strategically expanding our paid subscriber base globally,” said White. “We’re also planning to announce major new products and partnerships in the coming months that will extend the platform’s reach and capabilities.”
