19-year-old Cal AI co-founder raises $10M for Persona AI wearable

Zach Yadegari, the 19-year-old co-founder of calorie-tracking app Cal AI, has raised $10 million for Persona, a startup building a personal AI assistant that reportedly will include a $179 wearable band.

According to reports, the device is positioned as a lower-cost alternative to existing smartwatches, though details about its features—such as connectivity or software integration—remain limited. Yadegari previously exited Cal AI, which may have helped attract early backers, though the funding round’s structure and investors have not been confirmed.

Persona’s approach suggests an interest in bringing AI agents into physical form, a strategy that could appeal to consumers seeking dedicated hardware. This move contrasts with software-focused AI startups, some of which have recently gained attention for rapid valuation growth.

Questions remain about how Persona’s product will stand out, whether it will work with major platforms, and how it might compete with established players. If the wearable launches as planned, it could join a growing wave of startups exploring AI-driven consumer hardware.
