About NestSentinel | AI-Powered, Non-Intrusive Senior Safety

A personal story at the origin of NestSentinel

Created to offer a better answer.

NestSentinel was born from a deeply personal experience.

After the sudden passing of Pierre’s father, a new and pressing concern emerged:
How to ensure his mother’s safety at home – without invading her privacy or disrupting her independence.

Like millions of families, Pierre faced a difficult reality. Aging parents want to stay in their own homes, yet the risk of falls remains one of the most serious threats to their health and autonomy. Existing solutions promised reassurance, but in practice, they often fell short.

Why existing solutions are no longer enough

NestSentinel was designed specifically to eliminate these trade-offs.

Falls are the leading cause of injury-related hospitalization among seniors. Yet most current monitoring systems rely on outdated approaches:
