About ilonai
ilonai is a Swiss project building automatic fall detection for people living at home and, later, for care homes and assisted living. The first pilot started on 5 October 2026 in Ilona's home. We are based in Zug.

The name

ilonai is named after Ilona, the founder’s grandmother. She passed out twice in public. What stayed with the family afterwards was a single worry: if this happens at home, will anyone know?
The question wasn’t how to watch her more. It was how to know if she needed help without taking away her privacy.
That question became the product. The first pilot started on 5 October 2026 in Ilona’s home, so she can stay safe, with no live camera for anyone to open.
The product philosophy
ilonai learns as little as possible about a person’s life while still detecting a possible fall.
Ambient care platforms do a different job. They reconstruct daily behaviour, sleep and room activity in order to “know the resident,” and for some institutions that is the right choice. For an independent person at home, it is worth knowing only what a possible fall requires.
Three categories:
Traditional camera: a person can watch you.
Ambient care intelligence: an AI continuously understands your behaviour.
ilonai: an AI looks for the emergency and otherwise leaves your life alone.
We are not competing on accuracy slogans. We are building a safety appliance with a hard privacy boundary, owned locally, running on standard cameras.
