CareTech Human CEO Dan Matsui on Passive Health Sensing and Entrepreneurship
CareTech Human, a Cornell-incubated startup founded in Ukraine during wartime, has launched Biomonix, a toilet-mounted sensor system that passively harvests health data on metabolism, hydration, digestion and kidney function without requiring wearables, consumables or user effort, marking its expansion from clinical urology into the consumer wellness market.
The company, led by physicist and three-time founder Dan Matsui, officially unveiled the consumer wellness platform on October 5, 2026, Cornell Life Science Ventures reported. Matsui, who maintains offices in both Kyiv and Ithaca, first developed the underlying sensing technology in collaboration with urologists to automate tracking of urinary frequency, volume and flow.
The Bathroom as a Passive Measurement Point
CareTech Human describes its mission as building “a new layer of longitudinal health data by turning the bathroom into a passive measurement point,” combining contactless sensing, biofluid analysis and artificial intelligence to capture health signals from everyday routines, according to the company’s website.
The sensors clip directly onto a standard toilet bowl and operate invisibly in the background during normal use. The system deliberately avoids cameras and microphones, relying instead on contactless sensors to collect information, Cornell Life Science Ventures reported.
It functions as a multi-user platform with simple plug-and-play installation, requiring no consumables and virtually no effort from the user. This passivity is central to the company’s long-term vision, since technology must work in the background rather than depend on users remembering to log each interaction.
The approach addresses a specific gap in current health tracking markets. While wearable devices such as Oura, WHOOP, Fitbit and Apple Watch can measure heart rate, heart rate variability, sleep and activity, Biomonix is designed to capture biological signals found in urine and other waste products that those devices cannot detect.
The distinction matters particularly for monitoring hydration. Rather than relying on self-reported water intake, CareTech Human analyzes biological information that provides additional context about what is actually happening inside the body, the company reported.
Biomonix currently focuses on wellness insights related to hydration, recovery, digestion and urinary health, though the company sees potential in helping users understand whether changes to their diet, supplements or wellness routines produce meaningful physiological changes over time.
From Clinical Wards to Consumer Homes
Matsui founded the company in Ukraine and continues to operate from Kyiv despite the ongoing war, a challenge he discussed in the November episode of the Startup Cornell podcast, the Cornell Chronicle reported. The company is headquartered at Cornell’s Center for Life Science Ventures in Ithaca, New York.
The technology originated in clinical settings, where it automated information collection for urologists that was previously generated at home but outside of medical facilities, Cornell Life Science Ventures reported. Much of that data was difficult to capture in clinical environments, making passive home monitoring valuable for both patients and providers.
Biomonix represents the company’s expansion beyond the healthcare market into broader consumer health and wellness, applying technology originally developed and validated in medical applications to everyday users. The company officially launched the platform on October 5, 2026, and is now recruiting early adopters to test the product and provide feedback as it continues refining the technology and exploring new applications.
The Startup Cornell podcast, which features interviews with Cornell entrepreneurs sharing stories of success, failure and actionable advice for building businesses, is available on the Entrepreneurship at Cornell website as well as Apple Podcasts, Spotify and SoundCloud, the Cornell Chronicle reported.
Looking ahead, CareTech Human envisions bridging personal wellness and clinical care by eventually offering more comprehensive urine health assessments that could provide supplemental information for patients and their healthcare providers, according to the company’s website. This would build on the original clinical work while creating a bridge between home monitoring and professional medical care.
