Hi, I’m Guillaume — welcome to my new portfolio, so coool to launch on @Peerlist :)

I’ve been building products, teams, and companies for over 15 years.

I’m the founder of Nuage.to, a modern alternative to Google Drive built for teams. Over the years, I’ve served as CTO three times, led engineering teams of up to 27 people, and worked with 100+ startups across Europe, including Paris, London, and Berlin — as well as companies like Google, Total, and Zalando.

Alongside product building, I create content every day on YouTube as @codewithguillaume, where more than 180,000 people follow my work. I also run My Happy Agency, a web agency that has generated €1M+ in revenue, and I teach online courses that have reached over 5 million students worldwide.

I focus on shipping fast, scaling teams, and building sustainable companies. I sold one of my startups, Koachub, in 2022, and I currently advise 20+ founders across Europe and the US.

Outside of work, I’m a father of two (soon three) and split my time between France and the United States.
