YOU(th) Health Tech, a Berlin-based startup, has secured $4.5 million in fresh funding to bring preventive healthcare into the hands of every person with a smartphone.

The round was led by Callisto Health, joined by caesar., adesso Ventures, Antler, Moonstone, and 1024 Ventures. Notable angel investors, including Alan founder Jean-Charles Samuelian and HomeToGo CEO Patrick Andrae, also backed the vision.

The company has seen rapid traction, signing more than 20 contracts with clinics and health insurance providers as part of its B2B2C go-to-market strategy.

The new funding will be used to accelerate product development, with the majority allocated to expanding the engineering, data science, and medical research teams.

Tackles the barriers that keep people from screening

With global populations ageing and younger generations increasingly curious about longevity, preventive screening should be booming, yet 60% of people avoid it due to long wait times, expensive tests, and outdated equipment. YOU(th) addresses these barriers head-on by turning a device everyone already owns into a low-friction diagnostic companion.

This shift positions the company at the intersection of accessibility and precision, enabling frequent, non-intrusive monitoring across heart, lung, cognitive, skin, metabolic, mental, and blood health.

A founding team built for the longevity era

The company’s international founding team blends deep technical and clinical expertise. CEO Filippo Nigro, a TEDx speaker and former Product Lead at HomeToGo, drives the mission of redefining longevity for younger generations. COO Johannes Kraus previously built a machine-learning marketplace for health insurers, adopted by Munich Re. CTO Yuriy Dushin, a biostatistician and digital biomarker researcher published in Nature, leads the scientific architecture behind YOU(th)’s analytics.

Together, they are building a model where preventive care is continuous, convenient, and globally scalable, one smartphone at a time.

Reinvents screening through everyday devices

The company’s proposition is simple but bold. It aims to turn smartphones into powerful health-screening tools capable of spotting early risk signals in under two minutes. Its platform uses data from face videos, voice recordings, skin and eye images, typing patterns, and step behaviour to assess 50+ digital biomarkers across more than ten organ systems.

By removing the need for clinics, needles, or specialised hardware, YOU(th) makes health checks effortless. Early insights on blood pressure, oxygen saturation, respiratory symptoms, cognitive age, skin hydration, metabolic indicators, and more help users understand their health long before traditional symptoms emerge.

Filippo Nigro, founder and CEO of YOU(th), comments, “Our mission is to unlock prevention for 8 billion people. Everyone talks about prevention, yet only ~8% screen at the optimal frequency because time, cost, and friction get in the way. We remove those frictions by turning everyday phone behaviour, selfies, voice, typing, into passive health screening, seamlessly connected to real healthcare. Prevention shouldn’t interrupt life. It should run inside it. This investment allows us to extrapolate value from our unique database of digital biomarkers, blood biomarkers and DNA to bring predictive risk assessment to a global scale.”

Stefan Eckhardt, Managing Director at CallistoHealth, says, “We are happy to support the YOU(th) founders, as they solve a problem considered a hard fact by many: make relevant biomarkers accessible just through the technologies available in every smartphone and thereby enabling everyone to make more informed decisions.”

Christoph Klink, Partner at Antler, comments, “We have backed YOU(th) from the inception of the business because the team combines extraordinary technical depth with a clear vision for the future of longevity. They are building foundational infrastructure for preventive medicine that directly addresses the needs of an overstretched healthcare system. We have every confidence in their ability to lead this new category of digital health.”
