Three of the four co-founders bring full-stack expertise from Neuralink, NVIDIA, and SAP, plus 600+ volunteer hours in senior communities. Inspired by caring for grandparents with dementia and their novel research, they believe "presence", aware technology rather than input-driven apps, can help elders effectively leverage tech.

The fourth, Dr. Imran Mohiuddin, is a physician and Clinical Informatics Fellow at Stanford Medicine with expertise in outpatient care and AI healthcare transformation. Together with advisors from Stanford, Johns Hopkins, and Sutter Health, the team brings both technical depth and personal understanding to build Kaigo's integrated solution.

A YC F25 company (though not yet listed), Kaigo automates post-discharge check-ins, triage, and monitoring. It also offers a "digital interpreter" for companionship that feels human, with prompts as simple as "call my daughter.” They've learned from caregivers that isolation can kill faster than disease.

Large-scale Medicare studies show 1 in 5 seniors are back in the hospital within a month of discharge, and about 25% of those readmissions could be prevented with better follow-up. Kaigo pulling off a single percentage drop in readmission rates would translate into countless lives, and billions of dollars, saved.
