Career history
In the news
- On April 11 2026, Romain Pattyn and I sat at a notary in Brussels and signed the papers for Antasphere. Six months later, we've gone from €0 to more than half a million in total contract value. A few numbers, as plainly as I can put them. €500k+ in signed contracts, across 8 clients. €40k in annual recurring revenue, which starts as each build goes live. €60k+ average contract value. Signed is not cashed, and I want to be clear about that because numbers get inflated on here all the time. But every euro of it sits under a signed
- Waymo is the technology I’ve been waiting my entire life! SF has embraced autonomous vehicles like no other city I know! User experience is crazy, you book in 30sec in your phone, wait 5 minutes, and a self driving car picks you up to go anywhere you want! No small talk, no cow-boy freestyle driving, your own music in the car, laptop + 5G, you work like at your desk! I just fucking love this shit! What a time to be alive ⚡️
- Day 3 of SF Tech Week did not go as planned. In the best way. Yesterday we went to "The Product Loop", a workshop by Hexa and Amplitude. The question on the table: can products improve themselves? Can usage data, AI-generated insights and automated iteration take over parts of the classic build, measure, learn cycle? We came to listen. By the end of the evening, Romain Pattyn was on stage presenting Antasphere. That's the question we work on every day. Antasphere builds a software factory. We build software for clients, and we've
- Friday I was invited as a coach at an AI hackathon in Brussels. 9 teams, 10 hours, and my main goal was about challenging engineers about one thing: go-to-market. The brief: give hands, ears and a voice to computer-use agents, with the tech of H Company and Gradium. Laurane Colignon at Malt put the whole day together at WAT.BXL, with the Antasphere team. The execution was pretty impressive, and we could feel the tension. Laurent Hublet opened with a pitch of his own: Brussels is a tech city. Three arguments: the AI research has

- We've started working with Lina Law (HX26), about a month ago. They are changing de relation I have as a founder with Legal. It's like they are part of the team and understand all the context of Antasphere. Love their work !!
- Codika is now Antasphere 🌍 A year and a half ago I was a machine learning engineer in pharma, building models in a research team, and I knew I wanted to start something of my own. Romain Pattyn had built a CLI that let developers ship mobile apps in a fraction of the time. The idea was simple: I would build the AI layer on top so that agents could use it too. Two builders, one tool, let's go. It did not go like that. We changed direction more than once, sometimes for good reasons, sometimes because we were early and got it wrong.
