HINT is a Scandinavian hygiene technology brand developing automated disinfection infrastructure for buildings. Its system is designed to reduce the spread of infection through frequently touched surfaces, without relying on people to change their hand-hygiene habits. The company describes its approach as a fourth building system, alongside fire safety, heating and ventilation, and security.

HINT’s hardware uses sensors to trigger disinfection after someone releases a high-impact touchpoint. The initial devices target door handles, with plans to serve push plates, handrails, and shared equipment. Each cycle sprays 99% alcohol, which the company says dries in 12 seconds. Devices are intended for customer self-installation, avoiding contractors and building downtime.

The offering also includes automatically replenished alcohol canisters and an AI analytics platform. The software logs disinfection cycles, maps hygiene risks across a building, and helps operators assess risk reduction and return on investment. HINT invites office buildings, hotels, healthcare operators, and hospitality groups to apply for its limited private pilot program.
