Why we call it Companion.
The device sits with someone between visits. Every other name we tried described a machine doing a job. Companion describes the job.
The bedside device that runs CareOS is called Companion. We didn't land there quickly. For a few weeks the working name was Sentinel, then Aide, then Watch. Each one taught us something by being wrong.
The names we rejected
Sentinel sounded like surveillance. It put the device on the wall, watching the patient instead of sitting with them. Families hear that word and stiffen. Nurses hear it and assume the thing is auditing them. Wrong posture, wrong relationship.
Aide implied a subordinate role inside the care team. That made the device sound like a junior staff member with a pager. It also invited the question we never wanted: whose job is it replacing? The honest answer is none. It fills the quiet hours between visits.
Watch felt clinical and cold. A watch monitors. A watch alarms. A watch logs vitals on a strip of paper. None of that describes what happens at 3am when someone is scared and wants to hear a voice.
Naming as a forcing function
The job description of the device is companionship — sitting with someone, paying attention, being present. Once we wrote that sentence, the name picked itself. And then the name started doing work for us. Every time an engineer is about to ship a feature that beeps, escalates, or interrupts without warmth, the name pushes back. Would a companion do this? Usually the answer trims the feature down to something quieter.
We caught ourselves last week. A draft notification read Patient motion detected — escalating. We changed it to I noticed you moved. Are you okay? Same trigger, same downstream call, different posture. That edit happened because of the name on the box.
