Why now? In March, MyFitnessPal acquired Cal AI for an undisclosed sum after the app pulled in over $30 million in annual revenue in under two years. Yadegari and his co-founders joined the buyer, but he left in June and went straight to work on his next idea. He is building Persona with a co-founder who has yet to be announced.
What's the endgame? Persona is a personal AI assistant with a $179 wearable band, expected in December. Like rival consumer assistants, it can order food or rides, take notes, book travel, and answer emails.
What sets it apart? The band won't run ambient AI — it won't always listen. A button or a flick of the wrist activates the assistant. Yadegari says Persona runs its model in the cloud, encrypts data in transit and at rest, and lets users delete their data, so conversations stay private and can't be sold to advertisers or data brokers.
How does it make money? The business model relies on ads shown during shopping research. Yadegari says recommendations stay unbiased because the agent won't know which items are sponsored. Purchases require user approval and run through external providers such as Stripe Link.
What could go wrong? AI agents are vulnerable to phishing and prompt-injection attacks, as labs including OpenAI have warned. Yadegari says Persona is building in safeguards and that its agent can't see a user's credit-card details.
Traction: Persona launched as a free beta over iMessage and has drawn "a few thousand beta users." The band has generated "five figures in preorder revenue," Yadegari says.
The signal: Yadegari argues that everyday utility apps are collapsing into AI agents. "All of the utility apps that you use on your phone day-to-day, whether those are apps for shopping, whether it's Uber, DoorDash, your email — these are all collapsing," he says — a bet that funded wearable assistants are racing to prove.
