How Paid Influencers Drove Cal AI Past $30 Million and Into MyFitnessPal
Cal AI topped $30 million in two-year revenue before MyFitnessPal bought it, powered by paid influencers and Zach Yadegari's growth formula for viral reach.
Summary
Zach Yadegari, 19, founded AI calorie-tracking app Cal AI in 2024 and generated more than $30 million in revenue within two years before MyFitnessPal acquired it for an undisclosed sum in March 2026. An early influencer post delivered about 1,000 users in two days, prompting Cal AI to recruit and pay creators rapidly. Yadegari described a fast, linear relationship between posts, views and conversions.
Cal AI negotiated payouts tied to reach and usage, requiring creators to continue posting until targets were met, and prioritized influencers with small, tightly connected communities whose results were measurable. Yadegari, a Forbes 30 Under 30 alumnus, credited his family for supporting his ambitions but characterized college mainly as a social experience. In October 2026, he launched Persona, an AI agent startup that has raised $10 million. Persona plans a personal assistant available through iMessage, an app, email and phone calls, supported by a future hardware ecosystem intended to integrate computing more seamlessly with daily life.
