Guillaume M.

Start-Up CTO · AI Enthusiast 🌱

I have assisted multiple startups as a CTO for 8 years. During this time, I also co-founded a startup in London, which enriched my understanding of the CEO journey: what is pragmatic and impactful Vs what is not. Prior to this, I supported teams in companies such as Total, Michelin, and Sanofi.

I began with coding Flash games 19y ago.

I currently live in Marseille, France.
