Zach Yadegari, the 19-year-old founder of Cal AI, has quickly made a name for himself with his AI-driven calorie tracking app. Founded in 2024 shortly after Yadegari graduated high school, Cal AI saw viral growth largely due to a marketing strategy focused on enlisting numerous influencers to promote the app. Yadegari revealed during TechCrunch Disrupt that early influencer engagement brought a surge of about a thousand new users in just two days, prompting the company to aggressively recruit and pay more influencers to post content about Cal AI.

This influencer-driven growth proved both reliable and swift, generating a consistent stream of new users with each campaign. Yadegari explained that the company negotiated clear payout terms with influencers, a group he described as often being "broke college kids" who needed immediate cash. By setting expectations for reach and continued posting, Cal AI was able to scale its user base efficiently through social media communities that were tightly knit and easily measurable.

Cal AI’s success is underscored by its impressive financial results, having generated over $30 million in revenue within two years. This trajectory culminated in March with an acquisition by MyFitnessPal for an undisclosed sum. Despite his rapid achievements, Yadegari remains candid about his perspective on education, suggesting that college is more about social experiences than career preparation, a view that resonated with the audience at the event.

In addition to Cal AI, Yadegari is now expanding his ambitions with a new venture, Persona, an AI agent startup. Having recently secured $10 million in funding, Persona aims to create a seamless AI assistant that integrates across various platforms, including messaging and email, supported by a planned hardware ecosystem. This next step signals Yadegari’s intention to further blend AI technology with everyday computing experiences.
