MyFitnessPal (MFP) has finalised the acquisition of its fast-growing rival, Cal AI, the viral calorie-counting application built by two teenagers while they were in high school. The deal, which closed in December after nearly a year of talks, sees the seven-person Cal AI team, including its co-founders, join the larger fitness platform.
Cal AI, co-founded by CEO Zach Yadegari and Henry Langmack, achieved remarkable traction, amassing over 15 million downloads and generating an estimated $30 million in annual revenue in under two years. MyFitnessPal CEO Mike Fisher confirmed the entire team has been retained, with Yadegari continuing to lead the app as a unit within MFP while attending college.
Strategic Fit and Independent Operation
The Cal AI app will remain a standalone product, maintaining its core mission of using artificial intelligence to estimate calories from food photos. A key immediate upgrade for its users is integration with MyFitnessPal's extensive nutrition database, which contains over 20 million foods, 68,500 brands, and meals from more than 380 restaurant chains.
Fisher stated there are no current plans to merge Cal AI into the main MyFitnessPal app or to migrate its user base. He positioned the two services as complementary, catering to different user preferences. "We both do meal scan... But if MFP users take a picture of a hamburger, they can fine-tune the inputs right down to specifying three pickles, not two," Fisher explained. "With Cal AI, we realized that there is an audience of people that want... fast, AI-based [results]. They want it to not interfere with their life."
A Persevering Pursuit
Fisher revealed the acquisition process required significant perseverance, with initial contact made in early 2025 after MFP's competitive intelligence tools, like Sensor Tower, flagged Cal AI's rapid ascent in app store rankings. "We have been talking to them ever since, on and off," Fisher said.
He emphasised that the decision to acquire was driven not just by metrics but by the founders' serious dedication. Fisher cited details like the team holding its stand-up meetings on Sunday nights because Yadegari works on the startup throughout his school weekends. "You walk away saying this is an impressive young man," Fisher noted, dismissing any notion the venture was a hobby.
Founder's Journey and Deal Terms
The young co-founders' journey garnered significant media attention. Yadegari went viral on social media platform X last year after disclosing he was rejected by 15 of the 18 top colleges he applied to, despite a 4.0 GPA and running a successful company. He later told TechCrunch he initially intended to skip university but changed his mind after a summer in a Silicon Valley hacker house, concluding a degree would keep his options open.
While the specific financial terms of the acquisition were not disclosed, Fisher indicated the Cal AI team was satisfied with the offer, noting they "didn’t have to sell." Given the startup's substantial revenue, the deal is believed to represent a successful outcome for the now 19-year-old founders. Fisher declined to comment on the standard retention period for the team post-acquisition or any associated payout structures.
The acquisition underscores the ongoing consolidation in the health and fitness tech sector, with large platforms seeking to neutralise innovative competitors and capture new user segments through strategic purchases.
