Alex Iliescu.
I build AI products.

Former CEO of Mondly — the language app acquired by Pearson — and co-founder of Cratox. I counsel founders in AI, edtech and healthtech, and build products end to end.

About

I spent a decade turning a scrappy idea into Mondly — tens of millions of learners, an acquisition, and a long education in what makes products actually get used. I care about the seam where great design meets shipped software.

Today I'm co-founder at Cratox and counsel founders across AI, edtech and healthtech — and still build products end to end, research to launch. Below is what I'm working on.
