Sonitor Technologies

Sonitor Technologies, founded in 1997 by Ole B. Hovind, MD, M.P.H., operates as a specialized provider of real-time locating systems (RTLS) for indoor environments. Hovind, a medical doctor, envisioned a technology-based system to address common inefficiencies in healthcare, such as locating patient charts and mobile medical equipment. Headquartered in Oslo, Norway, with a significant presence in Stamford, Connecticut, the company commercializes high-definition, ultrasound-based RTLS primarily for the healthcare sector, including hospitals and long-term care facilities.

The company's business model centers on the development, manufacturing, and supply of its proprietary indoor positioning systems. Revenue is generated from the sale and licensing of its hardware and software platforms, which are designed to improve operational workflow, enhance patient and staff safety, and manage assets. Clients include over 300 healthcare installations, with applications ranging from asset tracking and patient flow management to infection control and nurse call automation.

Sonitor's core technology is its patented low-energy ultrasound system (SonitorULE™), which provides room-level and sub-room-level location accuracy. This technology is differentiated from other RTLS that rely solely on radio frequency or infrared signals. The company's flagship product, SonitorONE™, is a versatile platform that unifies multiple locating technologies, including ultrasound, Bluetooth Low Energy (BLE), and Wi-Fi, into a single infrastructure. This allows clients to tailor the level of accuracy to specific use cases, from precise, high-definition tracking for patient flow to broader zonal tracking for assets, using fewer devices than competing systems. The platform supports a variety of tags, badges, and the use of smartphones as tracking devices. A significant milestone was achieved in August 2025 with the strategic merger with Tagnos, a healthcare software company specializing in workflow intelligence, a move intended to create an end-to-end solution combining Sonitor's RTLS hardware with Tagnos's advanced software.
