About NestSentinel

NestSentinel is an elder-care technology company that provides an AI-powered monitoring solution designed to enhance the safety of seniors in their homes or at care facilities. The company was founded on March 6, 2026, by Pierre Marmignon, who serves as President. Marmignon's motivation for creating NestSentinel stemmed from a personal experience: after his father's passing, he sought a way to ensure his mother's safety at home, particularly from falls when she was alone. His background includes two decades in enterprise software and applied machine learning, with three patents in intelligent systems and the founding of a previous company that was sold to Citrix.

The company's core product is a non-intrusive monitoring system that detects falls and significant behavioral changes. A key differentiator is its privacy-by-design approach; the system uses a patent-pending, multi-sensor architecture rather than cameras or microphones, ensuring privacy is maintained. It does not require users to wear any devices or pendants. The technology is engineered to be context-aware, learning an individual's daily routines to distinguish between actual emergencies and false alarms, such as a dropped object. The system only actively monitors when the person is alone, as this is when a fall presents the most danger.

NestSentinel operates in the healthtech and senior safety market, targeting both individual private homes and larger care facilities as clients. The system is designed for seamless integration into the living environment, making the technology virtually invisible to the user. While anonymized data can be used to improve the system, this only occurs with explicit user consent. NestSentinel has been recognized by VivaTech 2026 as a 'Tech For Change' company for its contributions to health and society.
