Romain Simon

I've been building software since I was twelve. I graduated from SKEMA Business School (MSc in Entrepreneurship) in 2014. Today I run Yuki Capital, an AI product studio and portfolio company.

I founded Datananas in 2014, a B2B sales engagement platform. I grew it from a solo side project to a VC-backed company with a team of twenty. It was acquired by Sarbacane in 2020.

After seven years of building, I took a year off in 2022 to travel the world across 14 countries.

I believe AI makes it possible for one person to build things that used to require entire teams. I'm trying to prove that by building software, games, music, open-source agent skills, and research.
