TechCrunch Disrupt 2026: Cal AI’s Zach Yadegari on how to create viral growth and capitalize on it

Product founders can now learn how to turn early viral success into a lasting business from a peer who achieved it.

Zach Yadegari, co-founder of the AI-powered nutrition app Cal AI, will speak at TechCrunch Disrupt 2026 about how his company achieved viral growth and capitalized on it. Cal AI, which uses image recognition to track meals and calculate nutritional information, garnered over 15 million downloads and generated $30 million in annual revenue in under two years. Yadegari, who was 17 when he co-founded Cal AI and previously sold a gaming platform with over 5 million users for six figures at age 16, will discuss the rapid growth, product pressures, and challenges of converting initial attention into long-term user retention. Cal AI was acquired by MyFitnessPal in December 2025, retaining its team and app as a standalone entity, with Yadegari remaining at the helm.

The narrative of Cal AI's rapid ascent, from a high school project to a $30 million acquisition, highlights a significant trend in consumer tech: the potential for hyper-growth driven by AI-powered, easy-to-use tools. Yadegari's experience underscores the critical challenge of not just acquiring users through viral loops but sustaining engagement and building a durable company from that initial surge.

This case study is particularly relevant for founders operating in crowded markets, demonstrating that innovative application of AI for everyday problems can break through. The acquisition by MyFitnessPal also signals a consolidation trend where established players seek to integrate novel, fast-growing technologies and teams, potentially increasing the value of companies that can demonstrably manage viral growth effectively.
