Aging at home should not mean aging alone

We are building daily support around the person at home, the family who wants to stay connected, and the care team working alongside them. Useful technology starts with what each of those people needs.

Mission

Keep seniors sharp, safe, and independent — at home

Everyday support starts with the routines people want to keep: taking time for a conversation, remembering an appointment, and staying connected to family. We are building StaySharp around those moments at home.

Room sensors, a voice hub, cloud agents, and an app form the planned Gen 1 system. Older adults get daily support, families get approved routine summaries, and care teams can explore check-ins between visits. Features and response workflows will be tested with participating homes.

We are deliberately careful about the boundary. StaySharp is a general wellness product. It is not a diagnosis, not a treatment, and not a replacement for a caregiver or for emergency services.
