Personal AI assistant with a privacy-first wearable band
Persona is a personal AI assistant from Cal AI co-founder Zach Yadegari. Users can already chat with the free iMessage beta; a $179 Persona Band wristband (button or wrist-flick activation, not always-listening) is in preorder for a planned December availability. The assistant handles tasks such as booking, messaging, shopping research and notes, with encrypted cloud storage and user approval for purchases. TechCrunch reported a $10 million raise led by Vine Ventures with participation from Cory Levy (Z Fellows) and Collective Global on October 8, 2026.
