This 19-year-old sold his $30 million AI calorie-tracking startup. Now he's tackling doomscrolling.

• Zach Yadegari, 19, cofounded Cal AI, an AI-powered nutrition and calorie-tracking app.
• MyFitnessPal acquired Cal AI in December 2025.
• Yadegari is already working on his next business venture, a new brand called Flow.

On the Flow app, customers can set alarms and select which apps they’d like to block. When the alarm goes off, customers have to physically get up and tap their phone on the dock to turn it off. Tapping the dock also unblocks the apps.

Additionally, the Flow Alarm Clock can track users’ sleep patterns and record sleep sounds.

“I wanted to make something physical, but I didn’t want it to take a year of research and development,” Yadegari said. “It’s also something that would solve my own problems. I sometimes wake up, and I scroll on my phone for 30 minutes.”

Physical products are a new territory for Yedgari, but it’s one he’s been eyeing for a while. It doesn’t come without challenges, though.

“The elephant in the room is that we have to ship physical products and manufacture them,” Yadegari said. “We have to scale with the amount of supply that we carry, and that’s tricky. Shipping delays can also slow us down.”

Still, having experience from previously running a successful company has given Yadegari the confidence to start from scratch and try something new. Especially when the health and wellness industry is booming. The Global Wellness Institute said the wellness economy reached $6.8 trillion in 2024 and is forecast to hit $9.8 trillion by 2029.

“These are my favorite categories to work — health, productivity, and wellness — because they make a real impact on people’s lives,” he said.
