Don Yansen didn’t walk into the MIT AgeLab expecting to start another company. The serial entrepreneur, now retired and caring for his wife, was there as a study participant focused on technology in caregiving. But listening to fellow older adults describe how utterly defeated they felt by modern devices changed his calculus. “Can’t even use a modern cell phone,” he recalls them saying, and Apple Watches might as well be alien hardware for many in that demographic.
So Yansen did what MIT-trained electrical engineers do: he built something else. Kiwi Health, founded in October 2024, sells a wristband that strips away nearly every interface convention the tech industry takes for granted. No app grids, no tiny icons, no touchscreen gymnastics. Wearers talk to it. The band handles reminders, calls, texts, and health data sharing through voice commands, with AI interpreting speech patterns that shift as people age. It also tracks health metrics and pings caregivers automatically when someone falls.
The device sits at an interesting inflection point for AI wearables. Big tech keeps chasing younger users with ever-denser screens and notification-heavy experiences, while voice-first interfaces — the actual killer app for hands-free aging — remain under-served. Amazon’s Alexa and Apple’s Siri have spent years in this space without cracking it, largely because they’re bolted onto devices that still demand screen interaction for setup and management. A dedicated wearable built voice-first from the silicon up is a genuinely different bet.
Whether Kiwi Health can scale beyond a niche remains an open question. Hardware startups for older adults face brutal distribution challenges — convincing both seniors and their adult children to adopt new tech is a two-front sales war. But Yansen’s framing is refreshingly simple: “help seniors live the best life that they can.” If the wristband delivers even half of that promise without requiring a grandson to troubleshoot it every week, he may have found a market everyone else keeps overlooking.
