Flo Health ranked #1 in Sifted's top 100 consumer tech companies in Europe. Jun 11, 2026, 09:00 ET The inaugural list of the most significant consumer technology companies announced at SXSW London LONDON, June 11, 2026 /PRNewswire/ - Flo Health, the world's leading women's health platform and Europe's first femtech unicorn, was ranked #1 in the Sifted Consumer 100, Europe's first dedicated annual ranking of breakout consumer tech startups, demonstrating mainstream adoption, cultural momentum and global significance. The ranking was revealed live at this year's SXSW London during a ceremony at Juju's Bar and Stage, where Chief Financial Officer Tamara Orlova accepted the recognition before an audience of investors, media, and industry leaders. To determine the ranking, Sifted used a scoring model to assess companies across quantitative signals including fundraising track record, funding velocity, investor strength, employee growth and consumer traction, such as app-store performance, ratings, website traffic, search interest and social media mentions. Judges from Sifted's intelligence and editorial teams, alongside SXSW, scored companies across three areas: reach, meaning how widely adopted the product is among consumers; habit, meaning how deeply embedded it is in people's lives; and buzz, meaning the cultural momentum around the brand. The final ranking is designed to identify the European consumer startup with the strongest signs of breakout potential: products consumers are adopting, returning to and talking about, with the ability to scale beyond their home markets. "What makes this recognition especially meaningful is what it says about the future of women's health," said Tamara Orlova, Chief Financial Officer at Flo Health. "For too long, women's health was overlooked by the technology industry. Today, more than 81 million people trust Flo every month to support their reproductive health, fertility, pregnancy, and perimenopause journeys, demonstrating that women's health is not a niche category, but an essential part of everyday life." Building Trust at Scale Flo's top ranking comes as the company's approach to data stewardship has become increasingly central to its market position. The company's Trust and Safety Centre (flo.health/privacy-portal) is a publicly accessible hub where users can review Flo's privacy practices, certifications, and data governance commitments in plain language. The portal reflects a core principle the company has built its product around: trust is the product itself, not a prerequisite for selling one. Flo holds dual ISO 27001 and ISO 27701 certifications. It is the first and only period tracking app to achieve both. ISO 27001 covers information security management; ISO 27701 covers privacy management and maps directly to General Data Protection Regulation (GDPR) compliance requirements. Both certifications are independently verified and recertified annually. No other app in the femtech category holds the same combination. The company's Anonymous Mode allows users to track menstrual health, fertility data, and pregnancy information without linking any personal identifiers to their health data. The feature was recognized by TIME as a Best Invention in 2023, named a finalist for Fast Company's World Changing Ideas Awards, and won the IAPP Privacy Innovation Award in 2022. The underlying technology uses Oblivious HTTP (OHTTP) and post-quantum cryptography, a combination the company built specifically because existing standards were insufficient for the sensitivity of the data it handles. About Flo Health Flo Health is the #1 Health and Fitness app worldwide and the #1 OB-GYN-recommended platform for period and cycle tracking. In 2024, Flo became the first European femtech unicorn following an investment from General Atlantic and now supports 81 million monthly active users (MAUs) worldwide. Powered by a network of over 100+ medical experts, Flo guides women through every stage of their health journey - from menstruation to conception, pregnancy, and menopause - offering curated cycle and ovulation tracking, personalized health insights, daily educational content, and a private community for users to share questions or concerns. Through its Pass it on Project, Flo has donated 28M Flo Premium subscriptions to improve health literacy to women in need, aiming to reach up to one billion. A leader in privacy and security, Flo Health's Anonymous Mode feature was recognized as one of TIME's Best Inventions 2023 and also named a finalist for Fast Company's 2023 World Changing Ideas Awards as part of the company's commitment to privacy.

Dutch privacy group files complaint against Flo over handling of intimate health data. by Nikolaus Dreher Security News Published: 2026 June 2, 01:43 Dutch digital rights organization Bits of Freedom has filed a complaint against popular period-tracking app Flo, accusing the company of unlawfully collecting and sharing highly sensitive user health information. The complaint was submitted to the Dutch Data Protection Authority (AP), which is now being asked to investigate the app's data practices. According to Bits of Freedom, Flo allegedly processes large amounts of intimate personal information entered by users into the app, including menstrual cycle details, sexual activity, symptoms, headaches, cramps, moods, pregnancy information, and other health-related data. The organization claims users may not fully understand how extensively this information is collected and potentially shared. Flo is one of the world's most widely used fertility and menstrual cycle tracking applications, with millions of users globally. The app allows users to log reproductive health information, receive cycle predictions, and track symptoms related to menstruation, fertility, pregnancy, and overall health. The complaint argues that health-related information collected through apps like Flo falls under special-category personal data protections under the European Union's General Data Protection Regulation (GDPR). Under GDPR rules, companies processing sensitive medical or health data must meet stricter legal requirements regarding consent, transparency, and data protection. Bits of Freedom alleges that Flo's privacy practices may not satisfy those requirements. The organization specifically raised concerns about whether users are provided with sufficiently clear information about how their data is processed, who may receive access to it, and for what purposes the information could be used. The complaint also references concerns about online advertising and data-sharing practices involving sensitive personal information. Privacy advocates have repeatedly warned that reproductive health apps can create extensive behavioral profiles because users often disclose highly intimate details about their bodies, relationships, and medical conditions. Flo has denied wrongdoing and said it takes user privacy seriously. The company stated that protecting health data is a priority and that it complies with applicable privacy regulations. Flo also said users maintain control over their information and that the company has implemented safeguards designed to protect sensitive data.
Flo Health, the number one OBGYN-recommended women's health app, is launching new perimenopause tools as confusion around the life stage persists despite increased awareness. A survey conducted with Wakefield Research found 66% of US women aged 38–50 felt better prepared for puberty than perimenopause. According to a Flo study, one in three US women aged 35 and over still don't know if they're in perimenopause. The impact is significant: 52% of women in relationships say perimenopause has affected their partnerships, whilst 48% report impacts on exercise ability. Flo is introducing four doctor-backed tools for Premium users from May 2026, including a symptom checker, severity score tracker, menopause timeline and medically-verified relief options guide. The company raised unicorn status in 2024 and serves 80 million monthly active users globally.

"Being recognized by Google Play across multiple regions validates our approach to building an intuitive, accessible tool, whether on phones, watches, or emerging platforms." The award also reflects Flo Health's broader leadership in femtech. With tens of millions of monthly active users worldwide, the Flo App supports individuals through every stage of reproductive health, from cycle tracking and fertility awareness to pregnancy and menopause. Its wearable features complement the app's mobile experience, offering timely nudges and insights that align with users' daily lives.
