Non-contact vital sign monitoring for corrections — detecting self-harm, falls, and overdoses in real time.
Confirmed by founderRahm is building the human layer for intelligent systems, starting with correctional facilities. Their flagship product, Cell-Guardian, is a multi-sensor AI system that fuses radar, RGB, and thermal imaging with edge AI to continuously monitor inmate vital signs, detect self-harm, falls, overdoses, and unresponsiveness — all without physical contact. Founded by the team behind VetGuardian (a non-contact vitals monitoring platform acquired by Zomedica), Rahm is applying proven non-contact monitoring technology to the high-liability corrections market, with a roadmap to expand into elder care, healthcare, homes, and workplaces.

U.S. correctional facilities report over 300 inmate suicides annually — the leading cause of jail deaths — with facilities facing mounting civil liability from failure-to-protect lawsuits averaging $2M+ in settlements. Existing monitoring relies on correctional officers conducting manual cell checks every 15–30 minutes, creating dangerous blind spots. There is no scalable, non-contact solution that provides continuous physiological awareness without requiring inmate compliance or correctional staff augmentation.
Advanced sensors using Doppler Radar, FMCW technology, machine learning, and computer vision to track movement, velocity of internal bodily functions, blood flow, and respiratory rates in real-time without contact.
Rahm has $280K+ in executed purchase orders across 10 live county jail deployments, with a $2.0M qualified pipeline from facilities in active procurement. Signed distributor and integrator agreements provide a channel to 50+ additional facilities. Currently conducting live demos at monthly corrections trade shows with a 60-day average sales cycle from demo to PO.
Initiated the first Silver-Guardian pilot at 7 Acres (Cincinnati) in January 2026, marking entry into elder care and validating real-world deployment outside of corrections.
Silver-Guardian is registered as an FDA Class I medical device, enabling initial commercial deployment and establishing the regulatory pathway toward Class II (510(k)) clearance.
Received the first commercial purchase order for Cell-Guardian, marking the transition from pilot deployment to revenue-generating customer adoption.
