Polish-American health startup Mos Health has raised nearly €920K in pre-seed funding to develop its AI-driven preventive health platform and begin initial deployments in the U.S. market.
Founded by Patrycja Brzozowska, Mos Health is developing an AI Health Partner designed to help users turn health recommendations into consistent daily action. The platform analyses sleep, nutrition, lab results, and wearable data from devices such as Apple Watch and Oura to generate personalised health protocols.
Brzozowska previously served as COO and a founding team member at Wellbee, a Polish employee mental health platform acquired by Benefit Systems in 2024. She is joined by Paweł Chrzan, co-founder of Wellbee, and Paweł Sobkowiak, former CTO at Booksy.
According to Brzozowska, the idea for Mos Health emerged from personal experience. Generic advice often fails because it does not remove the friction of execution. The company aims to act as a step-by-step health partner rather than a passive recommendation engine.
Closing the execution gap in preventive health
Mos Health points to a significant gap between health advice and real-world adherence. Only around 25% of U.S. adults meet recommended activity levels, and most diets fail due to unsustainable routines.
To address this, Mos Health combines software and physical products. Alongside its AI-powered app, the company is developing proprietary supplements manufactured with a U.S.-based partner. These supplements act as the execution layer, helping users follow through on the app’s personalised protocols.

Backed by European early-stage investors
The pre-seed round was co-led by SMOK Ventures and Movens Capital, with participation from Tomasz Karwatka, Piotr Karwatka, Anna Lankauf, and additional angel investors.
The funding will be used to build the MVP, advance core technology, and support an initial U.S. launch.
Investors highlighted the founding team’s previous exit experience and global ambitions as key reasons for backing the company at an early stage.
Launching through employer-led distribution
Mos Health is entering the U.S. market with a B2B2C model, positioning its platform as a modern employee benefit. Employers can offer health-as-a-service packages that include personalised health protocols and supplements for their teams.
Early market validation is already underway, with the company signing its first letters of intent with Bay Area technology startups.
The team is supported by external advisors including Misa Beach, formerly at OpenAI, as a commercial advisor, and Dr. Oliver Zolman, a longevity specialist and co-creator of the Blueprint Protocol, as a clinical advisor.
