In a world crammed with “vibe coding,” Zach Yadegari, teen founding father of Cal AI, stands in ironic, old style distinction.
Ironic as a result of Yadegari and his co-founder, Henry Langmack, are each simply 18 years previous and lately graduated from highschool. But their story, thus far, is a traditional.
Launched in Might, Cal AI has generated over 5 million downloads in eight months, Yadegari says. Higher nonetheless, he tells TechCrunch that the shopper retention price is over 30% and that the app generated over $2 million in income final month.
Though TechCrunch couldn’t validate his obtain and income claims, Cal AI does have a 4.8-star score on the Apple App Retailer, with 66,000 opinions, and over 1 million downloads on Google Play with a 4.8-star score on practically 75,000 opinions.
The idea is straightforward: Take an image of the meals you’re about to devour, and let the app log energy and macros for you.
It’s not a singular concept. As an example, the massive canine in calorie counting, MyFitnessPal, has its Meal Scan characteristic. Then there are apps like SnapCalorie, which was launched in 2023 and created by the founding father of Google Lens.
Cal AI’s benefit, maybe, is that it was constructed wholly within the age of huge picture fashions. It makes use of fashions from Anthropic and OpenAI and RAG to enhance accuracy and is skilled on open supply meals calorie and picture databases from websites like GitHub.
“Now we have discovered that totally different fashions are higher with totally different meals,” Yadegari tells TechCrunch.
Alongside the best way, the founders coded via technical issues like recognizing substances from meals packages or in jumbled bowls.
The result’s an app that the creators say is 90% correct, which seems to be ok for a lot of dieters.

Teen coders and a hacker home
Yadegari can be incomes some fame for his early success. However, not like teen coders rising up with AI copilots, he was mastering Python and C# in center college, he mentioned.
Yadegari constructed his first enterprise within the ninth grade and sold it for $100,000 to a different recreation firm, FreezeNova, when he was 16, he tells TechCrunch. “After quarantine, faculties gave out Chromebooks to all of their college students, and unsurprisingly, youngsters tried to abuse this by taking part in video games in class,” he mentioned.
The varsity responded by blocking net entry to these recreation websites. So he “noticed a chance” to construct a web site that gave entry to all unblocked video games.
The most effective half? He known as the web site “Completely Science” so the college wouldn’t block it, too.
With that sale, he and Langmack watched Y Combinator movies and socialized with the coder crowd on X in search of a brand new concept. He met Blake Anderson on X, who additionally turned a Cal AI co-founder. Anderson, now 24, had earned notice as a young consumer app coder, too, for creating ChatGPT courting recommendation apps like RizzGPT and Umax.
Yadegari and Langmack had their concept after Yadegari started hitting the fitness center to realize weight and “impress ladies,” he mentioned, smiling.
Then they made one other cliché alternative: They moved to San Francisco to stay in a hacker home whereas constructing their prototype.
However whereas there, Yadegari, the son of two legal professionals, realized a contrarian lesson. He found he needed to go to school and never turn out to be a traditional Silicon Valley dropout kind.
“Twenty-four-seven grinding, sleeping on the ground, really, one of many nights, and it was a really enjoyable time, and it taught me lots,” he mentioned of the expertise.
However he appeared round. “We had been surrounded by those that had been of their late 20s or 30s all day. And I noticed that if I didn’t go to school, that is what life could be like.”
Whereas he hasn’t but decided which college he’ll attend, he and Langmack are nonetheless having enjoyable operating their firm. It now contains one other co-founder, Jake Castillo, 28 who’s COO and operating influencer advertising, in addition to eight full-time workers between builders, a designer, and social media managers.
