Health has always been a recurring theme in the conversations Alex and I had while building Mondly. We spent over a decade creating a global language learning product that reached over 150 million users, eventually leading to an acquisition by Pearson.
But behind the scenes, we were always reading research papers, testing wearables, and debating what the future of personal health might look like.
At some point, those conversations stopped being casual. They became something we couldn't ignore.
During the pandemic, something shifted for Alex. Like many people, he became intensely focused on long-term health preservation. But unlike most people, he didn't just read articles. He dove into scientific literature, decoded nutritional data, and began running personal experiments.
He explored every nutrition app, every wearable, every biomarker test he could get his hands on.
Some tools were helpful. Most were fragmented. And none of them spoke to each other.
There was no single place where your food, your blood tests, your genetics, your habits, and your goals could come together.
That's where the idea began to brew.
Around that time, AI was undergoing its quiet revolution. Alex and I had been experimenting with GPT-2 and GPT-3 since their early days. Tools like LLaMA, Stable Diffusion, and the first small open-source models were starting to hint at something big.
For most people, this was "interesting research."
For Alex, it was a once-in-a-generation opportunity.
He realized that AI could do something the nutrition world desperately needed: turn overwhelming biological data into clear, personalized, actionable advice.
The question became: What if everyone had a personal AI nutrition coach? A system that understood their body better than any app ever could?
That's when Alex started building the first version of what would one day become Cratox AI. Alone, at home, with nothing more than Cursor, Replit, and an obsessive determination.
The prototype was rough, but ambitious. It could:
We didn't set out to build another tracking tool. We wanted to move past counting macros and start uncovering what those numbers actually mean for the human body. Our goal was to step out of the crowded nutrition app market entirely and build something different: a system of AI-driven biological intelligence.
Fast-forward to today.
That early prototype turned into the foundation of Cratox AI.
We built an 8-person team of engineers, designers, and health-passionate people who share the same obsession with health, data, and building things that matter.
And recently, we hit one of the milestones that every product team remembers:
We submitted our first Cratox AI app to the App Store.
It's only the beginning, but it's a moment we're incredibly proud of.
Not because it's perfect. No first version ever is. But because it represents years of curiosity, learning, and conviction finally coming to life.
This blog post is the start of a short series where we'll share:
If you've been following our journey, or if you're just discovering Cratox AI now, I hope this gives you a glimpse into the passion and purpose behind what we're creating.
More stories are coming soon.
And thank you for being part of the beginning.
