How This 17-Year-Old Quietly Built a $1.12M/Month AI App
I stumbled upon his exact strategy from A to Z and it's brilliant.
What were you doing at 17?
If you’re like most people, it probably wasn’t making $1.12 million a month. I was busy figuring out how to parallel park and deciding whether buying a BlackBerry was a good idea (spoiler: it wasn’t).
Meanwhile, Zach Yadegari is quietly crushing it. He’s the mind behind Cal AI, an app that tracks calories using a simple photo. No logging. No spreadsheets. Just take a picture, and boom — calories calculated.
When I heard about this, I had to know: How does a teenager build something like this? Turns out, Zach didn’t stumble into success. He engineered it, step by step.
In a recent interview, Zach shared his process and showed us how he pulled it off. Let’s dive into what he did and how you can apply his strategies to your own projects.
