What SteadySense does
SteadySense GmbH, founded in February 2016 and headquartered in Raaba-Grambach, Austria, is a privately held biomedical engineering company that develops continuous body temperature measurement systems based on a proprietary adhesive sensor patch with NFC data transmission and companion iOS/Android applications. The company operates three product lines: femSense, a FemTech ovulation tracker (with an upcoming CE-approved BirthControl contraceptive extension) for women seeking natural family planning; STEADYTEMP Home, a consumer wearable thermometer for continuous family fever monitoring; and STEADYTEMP Professional, a clinical system for early infection detection in hospitals, nursing homes, and care facilities. All hardware, firmware, and software development is performed in-house, and products hold ISO 13485 certification, MDR compliance, FDA 510(k) clearance (obtained June 2024), and CE approval for the contraception indication.
The company generates revenue through hardware sales of sensor patches plus subscription/recurring software components via the femSense and STEADYTEMP apps. Go-to-market is hybrid: direct-to-consumer e-commerce through steadytemp.health and femsense.com for B2C SKUs, and enterprise field sales targeting hospitals, clinics, and nursing homes for STEADYTEMP Professional, with distribution leverage through Roche Diagnostics' cobas pulse system integration (since January 2022) and ilvi CLINIC, plus regional distributor Fleming Medical for Ireland. Key strategic investors include eQventure, Gartner Ventures, Situlus Holding, and Raiffeisen-Landesbank Steiermark, the latter co-investing in a 7-digit EUR round closed in October 2025.
SteadySense serves three primary customer segments: (1) healthcare facilities and professionals needing continuous infection monitoring and reduced nursing workload; (2) women of reproductive age using temperature-based fertility tracking or contraception; and (3) families and individuals seeking continuous home fever monitoring including during sleep. The company claims a EUR 200 billion addressable market across these use cases, with reported performance metrics of 99.73% ovulation detection accuracy and +/-0.1°C temperature precision. It is led by Managing Partners Werner Koele (CEO/founder) and Peter Gasteiner, with Bernhard Ungerböck as Chairman, and maintains an international subsidiary (SteadySense Inc.) in San Jose, California to support US market entry following FDA clearance.

SteadySense product offering
Product offeringCore offering
SteadySense develops and manufactures smart adhesive sensor patches that continuously measure body temperature at +/-0.1°C accuracy, transmitting data via NFC to companion iOS/Android apps. The portfolio comprises three branded offerings—femSense (ovulation detection with 99.73% accuracy), STEADYTEMP Home (family fever tracking), and STEADYTEMP Professional (clinical infection early detection)—all built on the same proprietary in-house hardware/firmware/cloud stack with ISO 13485 certification.
Product overview
SteadySense GmbH offers a portfolio of three main products based on continuous temperature measurement technology via smart sensor patches. femSense is a FemTech ovulation tracker (and upcoming BirthControl contraceptive) that measures body temperature 24/7 during the fertile window. STEADYTEMP Home is a consumer wearable thermometer for families, while STEADYTEMP Professional targets clinical settings and hospitals for infection early detection. All products use the same core sensor patch technology with NFC data transmission and proprietary apps for data visualization.
