Kintsugi

Kintsugi is a Berkeley-based AI company that built voice biomarker technology able to flag signs of clinical depression and anxiety from roughly 20 seconds of free-form speech. Founded in 2019 by Grace Chang and Rima Seiilova-Olson, it sold an API-first platform into call centers, telehealth, and remote patient monitoring before winding down operations in early 2026 and releasing its models, methods, and research into the public domain.
