Polish-American startup Mos Health raises nearly €920k for its AI-powered preventive health and wellness platform

Mos Health, a Polish-American startup building an AI Health Partner that combines personalised health protocols with matched supplementation, has raised nearly €920k ($1.1 million) in a pre-Seed round to build its MVP, develop its core technology, and initiate its first U.S. deployments.

The round was co-led by SMOK Ventures and Movens Capital, with participation from Tomasz Karwatka, Piotr Karwatka, and Anna Lankauf, among others.

“Mos Health was born from my own struggle to stay consistent. I realised that generic advice isn’t enough; we need a system that acts on our data and removes the friction of execution. We are building the partner I wish I had – one that guides you step-by-step,” said Patrycja Brzozowska, founder and CEO of Mos Health.

Founded by Brzozowska, Mos Health is a preventive health and lifestyle wellness company. Previously, Brzozowska was the COO and founding team member of Wellbee, a Polish mental health platform for employees, which was acquired in 2024 by Benefit Systems. Brzozowska is joined by Paweł Chrzan (co-founder of Wellbee) and Paweł Sobkowiak (former CTO at Booksy).

“As soon as I heard that Patrycja and Paweł were building a new startup, I immediately knew it would be a fit for SMOK. Serial entrepreneurs with a successful exit in Poland and ambitions for a much larger global win—that’s practically our investment template. We decided to back Mos Health within days of meeting the founders, and we’re keeping our fingers crossed for their success in the U.S. market,” said Borys Musielak, Partner at SMOK Ventures.

According to Mos Health, today, only 25% of US adults are sufficiently active, and most diets fail due to a lack of sustainable routine. The company claims to close this “execution gap” by providing a system that goes beyond recommendations and offers the physical tools to do it.

Its system comprises two key pillars. One is the AI Health Partner (App), which is a dashboard that analyses sleep, diet, lab results, and wearable data (Apple Watch, Oura) to generate personalised health protocols.

The second component is proprietary supplementation: a line of supplements manufactured with a partner in the United States, intended to serve as the physical “execution layer” for the application’s recommendations.

The company is launching in the U.S. using a B2B2C model, enabling employers to offer “health-as-a-service” to their teams. According to Mos Health, it allows companies to provide access to personalised protocols and supplements as part of a modern benefits package. Early market validation is already underway, with the team signing its first LOIs with Bay Area tech startups.

“We’re starting in the U.S. because it’s a market where innovation reaches companies and users much faster. The employee benefit model is a natural fit for us. We spend most of our day at work, and that’s where it’s easiest to introduce lifestyle changes that actually stick,” said Paweł Chrzan, co-founder of Mos Health.

The team is supported by external advisors, including commercial advisor Misa Beach, formerly of OpenAI, and clinical advisor Dr Oliver Zolman, a longevity specialist and co-creator of the Blueprint Protocol with Bryan Johnson.
