YON E Health Raises €250k To Develop Smart Vaginal Health Device

The round was led by PMK-Group, with participation from UniPrisma Venture Studio (Károly Szántó and Thijmen Meijer) and Matias Toye (founder of Oyster Shield and Dilicheck), who supported the startup’s M&A and fundraising strategy.

“When I started YON E, I was told vaginal health was too taboo, too complex, and too ‘niche’ for innovation and investment. That’s what motivated and pushed me even more,” said Roswitha Verwer, Founder and CEO.

YON E Health’s pre-Seed round underscores the growing diversity and momentum of FemTech investment in Europe in 2025.

While the Dutch startup focuses on developing a smart vaginal health sensor for real-time tracking of pH and basal body temperature, other European innovators are also gaining traction.

In the UK, Hormona raised €7.8 million to expand its hormone-tracking app, while France’s Solence secured €1.6 million to develop AI-powered digital therapeutics for PCOS. At the growth stage, SheMed closed €43 million to scale its personalised healthcare platform, and Unfabled brought its total funding to €3 million for its women’s wellness marketplace.

Together these rounds highlight a vibrant FemTech ecosystem spanning diagnostics, digital care and consumer health. YON E Health’s entry sits at the earliest frontier, marking a shift toward clinical-grade user-friendly devices designed to empower women through smarter data-driven reproductive health monitoring.

“For too long, women have had to guess, self-diagnose, or wait until they show symptoms and something goes wrong with their health. We’re changing that, turning silence into data women can actually use,” added Verwer.

Founded in 2022 by Roswitha Verwer, YON E Health is tackling one of the most overlooked gaps in women’s healthcare the absence of accessible, real-time data on vaginal health.

Its first product is an at-home medical device that continuously monitors pH and basal body temperature, providing accurate, science-based insights into fertility, infection risk, and overall vaginal wellness.

Operating globally with a multidisciplinary team across Amsterdam, Budapest, London, Texas, Boston, and Madrid, YON E Health represents a new generation of FemTech innovators combining data, design, and medical science to empower women’s reproductive health.

“Vaginal health isn’t a luxury; it’s a foundation of overall wellbeing,” adds Dr Muskaan Bhan, Chief Clinical Officer at YON E Health. “Our technology bridges the gap between research and reality, empowering women globally with real-time, clinical-grade insights that can prevent complications before they start.”

Despite impacting half the world’s population, women’s health remains one of the most underfunded areas in medicine. According to YON E Health, less than 1% of global medical research focuses on women-specific conditions, and in 2024, only 2.3% of venture capital went to female-founded startups — slowing innovation in key areas like vaginal health, fertility, and menopause.

The new pre-Seed funding gives YON E Health the resources to prepare for medical trials an essential step toward bringing its smart vaginal health device into clinical and everyday use.

Vaginal pH is a vital marker of reproductive and gynecological health. Imbalances can indicate infection risks such as bacterial vaginosis or yeast infections, as well as fertility and hormonal changes. Yet, most at-home testing still relies on single-use paper strips, often used only after symptoms appear — making care reactive rather than proactive.

YON E Health’s sensor technology changes this by continuously measuring vaginal pH and basal body temperature at home. This gives women and clinicians real-time insight into menstrual cycle patterns, microbiome health, and fertility windows. The data can help detect early imbalances, optimise conception timing, and support diagnosis in fertility or recurrent infection cases — empowering women with continuous, preventive health monitoring.

“YON E Health is addressing an area that’s both underserved and scientifically critical,” said Dr Peter M. Kovacs. “Their approach, combining biosensor technology, clinical expertise and user empathy, represents the future of proactive care in women’s health.”
