Zach Yadegari is one of the most exciting young founders in tech today. By age 18, he had built an artificial intelligence company that pulls in millions in revenue each year. His startup Cal AI helps users track calories using simple food images analyzed by AI.
Zach’s story catches attention not only for its rapid success but also for his unusual journey of self-learning, experimentation, setbacks, and big wins that defy traditional career paths.
Early Life & Education
Zach Yadegari was born and raised in Roslyn on Long Island, New York. His interest in computers started very early. As a child, he loved exploring how systems worked and spent long hours experimenting on his own. When he was 7 years old, his mother enrolled him in a summer coding camp.
Zach did not stop at basic lessons. He pushed himself beyond structured classes by watching online tutorials and carefully studying how code was built. His curiosity and focus helped him learn faster than most kids his age. By age 10, he wasn’t just consuming information, he was sharing it – charging $30 an hour to teach other kids how to code.
Alongside his technical skills, Zach stayed deeply committed to academics. He maintained a perfect 4.0 GPA and earned a 34 on the ACT. Even with these strong results, many top universities turned down his college applications, a surprising outcome that later attracted wide media coverage.
In the end, Zach chose the University of Miami for his studies. There, he continued to balance classroom learning with building and leading Cal AI, showing early signs of the focused founder he was becoming.
Career Start & Key Breakthrough
Before Cal AI became the most important startup chapter of his life, Zach had already started building real products at a very young age. Around age twelve, he launched his first mobile game called Speed Soccer. This project gave him hands on development experience that many students only gain during college years.
By 14, he created Totally Science, a website that allowed students to play unblocked games during school hours. The platform quickly gained massive popularity and began earning steady income through ads. After scaling its user base into the millions, Zach sold the business for about $100,000 when he was 16.
Later, while working to gain weight and improve his health, Zach faced constant frustration with slow and unhealthy calorie tracking apps. Along with his co founders, he saw a clear chance to use artificial intelligence to change food tracking. The goal was simple but powerful. Make it fast, accurate, and effortless. This idea turned into Cal AI, a mobile app that reads meals through a photo and delivers instant nutrition insights without manual work.
Company Overview: Cal AI
Cal AI is a mobile app built to make nutrition tracking simple with the help of artificial intelligence. Users click a photo of their meal, and the app automatically recognizes the ingredients, estimates portion sizes, and calculates calorie intake without long typing or manual entries.
Among countless health and fitness apps, Cal AI feels different because it puts AI at the center of the experience. Instead of depending on manual logs or old food lists, the app uses advanced machine learning to analyze food images. This approach turns calorie tracking into a smooth, accurate, and even enjoyable habit.
After its official launch in May 2024, Cal AI saw rapid growth and viral attention. Within a short time, it crossed millions of downloads and started generating strong monthly revenue, pushing the app into the global tech spotlight.
Major Achievements
- Sold his first project as a teen (Totally Science) for a six-figure sum at age 16, which he later invested into his next startup efforts.
- Built a company projected to generate over $30 million in annual revenue by age 18, a remarkable milestone for a founder so young.
- Achieved over 8 million total downloads for Cal AI within months of launch, showing rapid user growth and market adoption.
- Named on the Forbes 30 Under 30 (Food & Drink) 2026 list as a standout young entrepreneur reshaping food tech and AI nutrition tracking.
