MyFitnessPal has acquired Cal AI, the viral calorie app built by teens

MyFitnessPal Seals Deal with Teen-Run AI Startup Cal AI in Major Industry Shake-Up

In a landmark move that has sent shockwaves through the health and fitness tech industry, MyFitnessPal has officially acquired Cal AI, the AI-powered calorie counting app built by two high school students that skyrocketed to global prominence in under two years. The deal, which has been in the works for nearly a year, marks one of the most notable acquisitions in the health tech space, highlighting the meteoric rise of young entrepreneurs and the increasing role of artificial intelligence in personal wellness.

Cal AI, co-founded by 19-year-old Zach Yadegari and his high school friend Henry Langmack, has amassed over 15 million downloads and generated more than $30 million in annual revenue since its launch. The app’s core innovation lies in its ability to estimate calorie counts simply by analyzing photos of food—a feature that has made it a favorite among users seeking convenience and speed in tracking their nutrition.

Under the terms of the acquisition, Cal AI’s seven-person team, including Yadegari, will remain with MyFitnessPal. The app itself will continue to operate independently, maintaining its user-friendly mission while benefiting from integration with MyFitnessPal’s extensive nutrition database. This database includes 20 million foods, 68,500 brands, and meals from over 380 restaurant chains, significantly enhancing Cal AI’s accuracy and utility.

MyFitnessPal CEO Mike Fisher revealed that the acquisition talks began after Cal AI began climbing the app store rankings, catching the attention of MyFitnessPal’s competitive analysis team. “They definitely caught our eye early last year,” Fisher said, noting that the two apps are now neck-and-neck in the top rankings of their category on Sensor Tower.

What ultimately convinced Fisher and his team to pursue the acquisition was not just Cal AI’s impressive growth metrics, but the dedication and vision of its young leadership. Fisher recounted his first meeting with Yadegari in late spring of last year, describing him as “an impressive young man” whose commitment to the project was evident in every detail. For instance, Cal AI’s weekly stand-up meetings are held on Sunday nights—a schedule dictated by the founders’ school commitments but embraced by the entire team.

“This is someone who’s not doing this as a hobby,” Fisher emphasized. “They’re really serious about it.”

The acquisition also underscores the growing influence of AI in the health and fitness sector. While MyFitnessPal caters to users who prioritize accuracy and detailed tracking, Cal AI appeals to those who value speed and simplicity. “We both do meal scan,” Fisher explained, “but if MFP users take a picture of a hamburger, they can fine-tune the inputs right down to specifying three pickles, not two. With Cal AI, there is an audience of people that want it fast, they want AI-based. They want it to not interfere with their life and not have to think about it much.”

Despite the acquisition, MyFitnessPal has no immediate plans to integrate Cal AI into its main product or to migrate Cal AI users to the MyFitnessPal platform. Instead, the company sees the two apps as serving complementary markets, each with its own unique value proposition.

The deal is a significant milestone for Yadegari and Langmack, who have already achieved what many entrepreneurs only dream of. Last year, Yadegari went viral on social media after revealing that he had been rejected by 15 out of 18 top colleges he applied to, despite maintaining a 4.0 GPA and running a successful company. At the time, he told TechCrunch that he hadn’t initially planned to attend college, preferring to focus on his startup. However, a summer at a Silicon Valley hacker house surrounded by college dropouts convinced him that a degree could open more doors in the long run.

Now, as a college student and the head of a MyFitnessPal-owned company, Yadegari is poised to continue shaping the future of health tech. Fisher declined to comment on the retention period for the Cal AI team or the specific terms of the deal, but industry observers speculate that the outcome was highly favorable for the young founders.

The acquisition of Cal AI by MyFitnessPal is more than just a business transaction—it’s a testament to the power of innovation, the potential of young entrepreneurs, and the transformative impact of AI on everyday life. As the health and fitness tech landscape continues to evolve, this deal sets a new standard for what’s possible when vision, technology, and determination converge.
