By Felo News Desk · Published
Zach Yadegari, the teenage co‑founder of calorie‑tracking app Cal AI, announced the launch of Persona, an AI‑powered personal assistant, after raising $10 million in a financing round led by Vine Ventures, with participation from Z Fellows founder Cory Levy and Collective Global.
What happened
Persona was unveiled as a software‑first service that currently operates as a free beta via iMessage. The startup also plans a hardware component – a wearable band priced at $179 – expected to ship in December. The band will feature a push‑button or wrist‑flick activation, differentiating it from ambient AI devices that listen continuously.
What the report adds
TechCrunch reported that the band will not store user data or run the AI model on‑device; instead, processing occurs in the cloud with encryption in transit and at rest. The company says users can delete their data, and the assistant will not have access to credit‑card details, requiring explicit approval for purchases through providers such as Stripe Link. While the business model includes advertising during shopping research, Yadegari claims the AI will present unbiased recommendations because it cannot identify which items are sponsored.
What was said
Yadegari told TechCrunch that privacy was a core design goal, noting that “Persona doesn’t run its AI model or store user data on the device.” He added that the startup has already generated “five figures in preorder revenue” for the band and attracted “a few thousand beta users.”
How it came about
After MyFitnessPal acquired Cal AI in March 2026, Yadegari and his co‑founders stayed on to develop the app before he left the larger company in June to focus on Persona. The funding round follows his earlier success, where Cal AI reportedly earned over $30 million in annual revenue within two years.
