I think we’ve gone a little too far when we feel the need to have our doorknobs automatically sanitized every 15 minutes to feel clean.
SIMON SASSOON saw the future in a dream. Mr. Sassoon, a former watch designer, dreamed he was standing in a women’s public restroom, which his hygiene-conscious girlfriend had just left. Attached to the door above the knob was a white plastic box.
As Mr. Sassoon’s dream self watched, the box made a gushing sound. Out from the bottom sprayed a fine dry mist, which bathed the metal knob and killed every germ on it.
The girlfriend is now an ex, but two years and $250,000 of investment capital later, the HYSO, an acronym for Cantonese words meaning “happy hands,” is starting to roll off production lines. Mr. Sassoon, 44, a nephew of the hairdresser Vidal Sassoon, is betting there is a vast and rapidly expanding market for a $60 device that sprays a hospital-grade disinfectant on doorknobs every 15 minutes.
