Why it matters
The story illustrates the evolving landscape of digital marketing and the high-speed growth potential of AI-driven consumer applications.
Zach Yadegari has enjoyed an immense amount of success for someone who only recently graduated from high school. Founder of the AI-fueled calorie tracking app Cal AI, Yadegari is only 19, but his company has rocketed to viral fame over the past two years. At TechCrunch Disrupt on Thursday, Yadegari shared details of that surprising rise to prominence.
Cal AI, which was founded in 2024, exploded its presence on the internet thanks largely to Yadegari’s strategy of deploying a small army of influencers to promote the brand. The company generated over $30 million in revenue in two years and was acquired by MyFitness for an undisclosed amount of money in March.
Discussing his social strategy onstage, Yadegari noted that an early sign of success came when an influencer’s post about them led to approximately a thousand new users over the course of two days.
