Cal AI just passed $1 million in revenue. Today was my first day of high school senior year. Was this destiny? Did I will this into existence? Luck? I don’t know.

$200k in 24 hrs. Cal AI is less than 2 years old. So much room to grow.

Cal AI has been acquired by MyFitnessPal 🚨 Henry and I started Cal AI as 17-year old high school students with one mission: make calorie tracking easier with AI. In just 18 months, we’ve helped millions of people lose millions of pounds. And we broke $50m in ARR along the way.

How it spread
Trace the originCal AI sold photo-based calorie tracking through paid fitness creators, then added paid ads. Publicity around its student founders brought TV coverage. MyFitnessPal bought the app; its announcement reported over $40 million in trailing-year sales.
Documented milestone; not a measured attention peak.
