Zach Yadegari sold his first startup at 16 for six figures. At 17, he built a calorie-tracking app that MyFitnessPal eventually acquired after it crossed $30 million in annual revenue. Now 19, he's back with a more ambitious pitch: an AI assistant that lives in your iMessage thread and, if you pay extra, on a sleek aluminum band around your wrist.
Persona raised $10 million in a round led by Vine Ventures, the company disclosed Tuesday. The funding comes roughly three months after Yadegari launched the service publicly in September, signing up several thousand beta users and banking what the company describes as "five figures" in preorders for the $179 Persona Band. Shipping begins later this year, though the exact timeline remains fluid.
The premise sounds straightforward. Text the assistant through iMessage to book dinner, reschedule meetings, or cancel that forgotten streaming subscription. Or slip on the wristband, press a button, and speak your request into one of two microphones the company claims can detect a whisper. An LED ring glows while the system processes. Approvals pop up on your phone. Stripe Link handles payments.
What Yadegari is really selling, though, is a theory about how software will consolidate. "All of the utility apps that you use on your phone are collapsing into a single super app powered by an AI assistant," he told TechCrunch. It's a vision shared by much larger, better-funded competitors who announced similar products within days of each other in September.
Meta unveiled Muse on September 8th, an assistant that threads through Facebook, Instagram, and WhatsApp. Three weeks later, Instinct closed a $1 billion round at a $10 billion valuation. That startup began with text-based assistance and recently added voice calls. Amazon snapped up Bee, a wearable focused on recording and summarizing conversations, in July 2025—a deal that drew immediate privacy scrutiny.
Persona occupies an uneasy middle ground. Unlike Bee, which listened continuously, the band only activates when you press a button or flick your wrist. Unlike Instinct, which started entirely in software, Persona is shipping hardware within months of its public debut. The device weighs 27 grams, runs three days per charge, and stores up to two days of data locally if your phone disconnects. It's water-resistant. It supports more than 120 languages.
The software, available now for free via iMessage, connects to the usual suspects. Gmail. Google Calendar. Notion. Slack. Zoom. Uber. DoorDash. The backend runs in the cloud, processing requests and routing them to the right service.
Preorders opened at $179, framed as a $40 discount off a $219 retail price. Free shipping within the U.S. Whether enough people will wear a dedicated AI assistant on their wrist to justify manufacturing costs is the central gamble.
Yadegari has some experience reading consumer behavior. Before Cal AI, he ran a site called Totally Science that let students play unblocked games at school. He sold it for $100,000 while still in high school, according to TechCrunch. Cal AI grew to 15 million downloads before MyFitnessPal acquired it in a deal announced this past March. Yadegari left MyFitnessPal in June, three months before launching Persona.
He's scheduled to speak at TechCrunch Disrupt this fall, discussing viral growth tactics—a subject he knows well.
The $10 million will fund AI inference costs, which Yadegari says are necessary to keep the software free. The rest goes toward hiring, manufacturing the wristbands, and marketing. Cory Levy of Z Fellows and Collective Global joined the round, TechCrunch confirmed.
Persona operates under the legal entity Iris Assistant Inc. The company filed a trademark for "Persona" on September 15, the same day its privacy policy and terms of service went live. Revenue currently comes from sponsored shopping results displayed alongside organic recommendations. Yadegari told TechCrunch the assistant "won't know which are sponsored," an approach that raises questions about transparency but mirrors how search engines have long blended ads into results.
"Our mission is really to just make computing seamless with human life," Yadegari said. "It can offer help and solve problems before you even know you have a problem."
Whether people want their problems solved before they notice them—and whether they'll strap on a wristband to make it happen—will become clear soon enough. The company is targeting holiday shipments. By then, the broader market for AI assistants may look very different. Meta and Instinct aren't standing still, and the appeal of talking to your wrist instead of your phone remains unproven outside early adopter circles.
For now, Persona has cash, a few thousand believers, and a 19-year-old founder with a track record of selling things people didn't know they wanted.
