Grace Chang

Grace Chang is the Taiwanese-American founder and CEO of Kintsugi, the Berkeley-based startup that built AI capable of detecting clinical depression and anxiety from just 20 seconds of free-form speech. A five-time entrepreneur with roots in signal processing and consumer tech, she raised $28 million, launched Japan's default mental health screener, and built the world's largest annotated voice dataset for mental health machine learning - before making all of Kintsugi's research and technology open source in early 2026 after FDA regulatory hurdles made the venture-backed model unsustainable.
