MyFitnessPal Acquires AI Calorie Tracking App Cal AI, Sales Exceeding $40 Million in the 12 Months Prior to Acquisition
MyFitnessPal announced the acquisition of the AI calorie tracking app Cal AI in March 2026, with the deal completed in December 2025. The terms were not disclosed. Cal AI was founded by high school students Zach Yadegari and Henry Langmack, estimating food calories through photos, achieving over 15 million downloads in less than two years, and generating over $40 million in sales in the 12 months prior to acquisition (some reports indicate annual revenue exceeding $30 million).
Cal AI's growth heavily relies on creator marketing. Its CMO Jake Castillo detailed the specific approach in a Starter Story Build video: instead of targeting major influencers, they seek ordinary people to create new accounts specifically for the app. They start by testing 10 pieces of content at $10 each, and if successful, they sign contracts for 30 pieces per month at $30 each, then scale up.
New accounts need to be nurtured: spending about 30 minutes daily engaging with videos in the same niche, initially posting a few non-branded contents, and once one post exceeds 1,000 views, they promote to reduce the risk of being limited by the platform. Content format is adjusted based on product characteristics: if the app has strong surprise moments, they create viral stories to pursue views; if not, they first address pain points before introducing the app, aiming for conversion.
Example calculations show: spending $900 to buy 30 videos resulted in 600,000 views, with a CPM of about $1.5; ultimately bringing in 120 paying users and $2,400 in revenue, with an RPM of about $4. Increasing investment is only worthwhile when RPM exceeds CPM. This system helped Cal AI scale rapidly and ultimately be acquired, with the team and app continuing to operate independently while integrating into MyFitnessPal's nutrition database.
This acquisition is part of an event-driven category consolidation, with MyFitnessPal enhancing its photo tracking capabilities by purchasing a high-growth AI app; the beneficiaries are the founding team of Cal AI and MyFitnessPal's product matrix, while competitors relying on traditional manual recording face pressure, as the AI-native experience and low-cost creator traffic are changing customer acquisition cost structures.

Cal AI was founded by 17-year-old high school student Zach Yadegari in 2024, starting from scratch and achieving tens of millions in revenue within 18 months through systematic creator collaborations before being acquired. After the deal, Yadegari left to start a new project, Persona, which raised $10 million; its growth path is centered on non-VC, high-density creator execution.
In terms of capital, the company directly converts its marketing budget into creator content procurement, forming a replicable customer acquisition machine through low-cost testing, nurturing accounts, standardized contracts, and RPM/CPM calculations. Ultimately, it was acquired by MyFitnessPal as a high-revenue, independent app; the motivation was to quickly monetize the AI photo experience with an existing user base, avoiding long-term independent operational traffic costs.
This is analogous to the early consumer application path on TikTok, which leveraged a large number of small to medium creators, and some health products replacing traditional advertising with UGC. Cal AI is in the expansion phase from manual testing to a scaled creator network; compared to apps relying on major influencers or purely paid advertising, it emphasizes account control and content replicability.
Essentially, this represents a technological substitution: traditional applications rely on the pricing power of major media or top influencers for customer acquisition, which is being partially replaced by low-cost, testable, and replicable ordinary creator accounts. The mechanism occurs as short video platform algorithms favor new accounts and authentic content, allowing small-scale testing to validate conversion, thus transforming marketing from creative gambling to calculable traffic procurement.
