The Challenge
The Growing Concern of Living Alone
For millions of people living alone worldwide, a simple question haunts them: What if something happens and no one knows?
The phenomenon of "kodokushi" — unnoticed deaths — has become a pressing concern, particularly in Asia where urbanization and changing family structures have left many without daily contact. In Japan alone, tens of thousands of such cases occur annually.
Demumu was created to address this growing concern with a solution that's simple, private, and effective — creating an invisible safety net for those who live independently.
