Why I study solo founders

Some years ago I worked on a product that took a team of 35 people 13 months to launch. Nobody thought that was unusual. It was simply what building a product required.

Today I see founders launch comparable products alone, in weeks, with AI doing a large part of the work. I believe this is more than a curiosity. It changes who can start a company, what a founding team is for, and how investors and startup programmes should judge the people in front of them.

I decided to study it properly. In 2026 I started a PhD at Universidad Pontificia Comillas in Madrid on what I call Gen AI solo founders. The Solo Thesis is where I share the published evidence along the way.
