After losing his father, Pierre needed a way to keep his mother safe at home — especially from falls, when no one was around. Every existing solution demanded the same compromise: accept surveillance, or accept the risk. He refused both. NestSentinel detects falls and behavioral changes using a proprietary multi-sensor architecture (patent pending) that captures what traditional systems miss. It learns the rhythm of each person's daily life — and only monitors when they're alone. Because that's when falls are most dangerous: not when they happen, but when no one is there to respond. No cameras. No wearables. No pendants to forget in a drawer. No personal data stored. Anonymized data improves the system only with explicit consent. Privacy isn't a feature. It's the foundation. Where basic motion detectors flood caregivers with false alarms, NestSentinel distinguishes a real fall from a dropped cushion — context, not just movement. Installation is invisible. Works in a private home or a care facility. Alerts reliable enough to trust, quiet enough to live with. Pierre Marmignon brings twenty years in enterprise software and applied ML — including a company he founded, scaled, and sold to Citrix in 2016, plus three patents in intelligent systems. Louis Baumstark brings a decade of digital product building and go-to-market strategy — including an online education platform he built and sold. They share a conviction: technology should protect people without diminishing them. The people who raised us deserve safety that doesn't cost them their dignity. → Working in eldercare, healthtech, or senior safety? We'd welcome the conversation.
