The short version
Zach Yadegari, 19, launches Persona after selling his Cal AI project to a larger app into a larger health platform for an undisclosed sum, and now raises $10 million for the new venture.
Persona pairs a $179 wrist-worn band with a cloud-powered AI model to handle everyday tasks through a single assistant.
The product starts with a free beta where users interact with the agent via iMessage, and the band is slated to ship in December.
The startup plans to show ads during shopping research but says recommendations are driven by user preferences and not sold to advertisers.

Zach Yadegari, 19, launches Persona, a wrist-worn AI assistant with a cloud-based model designed around privacy. The project has $10 million in funding and a December hardware release.
What to know:
Product: A $179 wearable band paired with a cloud AI model; beta via iMessage.
Funding: $10 million led by Vine Ventures.
Privacy: Data encrypted in transit and at rest; purchases require user approval.
Why it matters: A wrist-based AI agent could offer a more private, always-on helper without needing to pull data from multiple apps. What happens next: December ship date for the band and broader app expansion afterward.
A teenage founder is back with a new idea aiming to blur the line between wearable devices and everyday AI help. Zach Yadegari, now 19, has launched Persona, a personal AI agent startup that pairs a slim wrist-worn band with a cloud-based model to power a hands-on assistant for daily tasks.
Persona has already attracted $10 million in funding, led by Vine Ventures, with participation from Z Fellows and Collective Global. The team describes Persona as a privacy-first assistant that runs its AI model in the company’s cloud rather than on the device. Data gets encrypted in transit and at rest, and users can delete their data. Purchases triggered by the agent would require the user’s explicit approval through external providers like Stripe Link.
The hardware side is a wearable band priced at $179, expected to arrive in December. In the meantime, the company has begun a free beta where people can converse with the assistant through iMessage. The plan is for the wearable and app ecosystem to grow together, letting the agent handle tasks like ordering food or rides, taking notes, booking travel, answering questions, and managing emails through a single interface.
On the strategy side, Persona aims to make a compelling case for privacy in a space crowded with AI assistants. The data travels to Persona’s cloud model, and conversations are encrypted both ways. The company says it designed safeguards to guard against phishing and prompt-injection attempts, and it notes that the agent won’t access sensitive payment details. When it comes to business model, Persona will feature ads during the shopping research flow, but the team emphasizes that recommendations are guided by user preferences, not by a knowledge of which items are sponsored.
Beyond the hardware, the vision is to turn the wearable into a gateway to a broader app ecosystem. If the beta and first releases land as planned, December will mark the first time many users can try Persona in the real world, with the app ecosystem expanding later.
Persona stands out for its backstory: a young founder who has already launched and pivoted in the AI space and is now pursuing another venture with a clear emphasis on user privacy and a wearable form factor that could make daily AI help feel less obtrusive.
