Cal AI Hit 15 Million Downloads and $30 Million Revenue Before MyFitnessPal Deal
Cal AI topped 15 million downloads and $30 million in annual revenue before MyFitnessPal acquired it, with Zach Yadegari still leading its seven-person team.
Summary
Zach Yadegari co-founded Cal AI at 17 while still a high school senior. The AI nutrition app uses a meal photo, image recognition, and a phone’s depth sensor to calculate calories, protein, carbohydrates, and fat. In under two years, it surpassed 15 million downloads and $30 million in annual revenue. MyFitnessPal acquired Cal AI in a deal completed in December 2025, before Yadegari turned 20, while retaining the seven-person team, keeping the app independent, and leaving him in charge. At 16, Yadegari had sold Totally Science, his gaming platform with more than 5 million users during the COVID-19 pandemic, for six figures.
Yadegari will discuss viral distribution, product pressure, durable retention, and long-term company building in the Builders Stage session “How to Create Viral Growth and Capitalize On It” at Disrupt 2026. The event runs October 13 to 15 at Moscone West in San Francisco, with more than 10,000 founders, investors, operators, and technology leaders, 250-plus speakers, 200-plus sessions across six industry stages, and 300-plus exhibiting startups. Passes are discounted by up to $200 until September 25 at 11:59 p.m. Pacific, with second passes 50% off for select ticket types.
