Holi closes EUR 3M seed round to take its digital obesity treatment model international
Holi, a Polish healthtech startup building an innovative digital obesity clinic, has raised EUR 3 million in seed round led by 4growth VC (Poland) with participation from YZR Capital (Germany), Heartfelt Capital (Germany) and a group of business angels. The company will use the funds to enter new European markets and further develop its data-driven care platform.
Holi combines medical expertise with technology, offering a multidisciplinary care model for patients living with obesity. According to the World Health Organization, more than 800 million people worldwide are currently living with obesity, and this number is expected to almost double by 2035.
Holi’s platform provides access to doctors, psychodietitians, psychologists and physiotherapists, as well as GLP-1-based pharmacotherapy, including drugs such as Ozempic and Wegovy. Patients use a mobile app and an online platform to receive personalized treatment plans and coordinated care.
“Obesity treatment requires continuity and the integration of multiple medical competencies,” says Paweł Seweryn, Founder & CEO of Holi. “Our goal is to deliver a comprehensive solution that leads to real, long-term change in metabolic health. The funding will enable us to scale our model internationally – starting with the Southern and Eastern Europe markets, which are highly receptive to private healthcare and telemedicine – while further developing our technology stack.”
The funds will be allocated to scaling Holi’s medical infrastructure and enhancing its technology capabilities, including diagnostics integration, GLP-1 tracking, automation of care processes and new engagement features designed to sustain patient motivation over time.
Holi’s model delivers significantly stronger clinical outcomes compared to standalone GLP-1 treatment. Patients using the platform achieve on average a 17% reduction in body weight after 12 months – around 1.5x more than pharmacotherapy alone. By combining data-driven dose optimisation with behavioural coaching, Holi also helps patients cut their medication costs by up to 50%, making long-term treatment more accessible and sustainable.
“The next generation of obesity treatment will be hybrid – data and AI for precision, experts for impact. Our platform continuously analyses patient data to adjust therapy in real time, while doctors and specialists step in exactly when human intervention matters most. That’s how we deliver better outcomes with smarter use of medication,” explains Jan Kundziołka, Co-Founder of Holi, responsible for product and technology.
According to WHO data, more than 800 million people worldwide are currently living with obesity, and nearly two billion are overweight. Obesity is now classified as one of the largest global public health challenges, contributing to more than 200 medical conditions and driving increasing pressure on healthcare systems.
“Obesity remains one of the most underserved health needs globally. Holi has built a truly efficient care model – virtual, scalable and designed with a genuine value-for-money mindset. It delivers clinically proven outcomes at a price point that makes sense for both patients and the business. This combination of medical impact and smart product design is exactly what convinced us to invest,” says Krzysztof Bachta, Managing Partner at 4growth VC.
The EU obesity treatment market is estimated at EUR 40-50 billion, with private healthcare spending rising rapidly as GLP-1 drugs such as Ozempic, Wegovy and Mounjaro become more widely adopted by patients.
“Since our initial investment, Holi has shown remarkable progress – both in clinical outcomes and operational execution. The company is scaling fast while maintaining strong medical standards, which is rare in this market. That’s exactly why we decided to significantly increase our backing in this round,” says Markus Feuerecker, Co-Founder and Managing Partner at YZR Capital.
