I'm Cedric, based in the UK. By day I'm Head of Data & AI at Firgun Ventures, where I'm building an intelligence system to support investment decisions in the emerging Quantum Computing landscape. In parallel, I'm Lead AI Lecturer at Le Wagon — the #1-rated coding bootcamp worldwide — where I've taught Data Science, Data Engineering, Data Analytics, and GenAI for 4+ years.
For Le Wagon B2B, I've designed and delivered AI programmes for teams at Warner Music, SLB, ODDO, Engie, Stellantis, Eiffage, Roland Berger, and Bain & Company — and authored their GenAI for Data Scientists bootcamp, Advanced RAG course, and GenAI & SQL course. I also run Agentic SEO, a boutique AI SEO consultancy, and I'm the author of an Amazon bestselling book on AI.
Before Firgun I was Technical Co-Founder of an e-commerce brand, a Data Engineer / PowerBI Consultant at element61 (Belgium's most experienced BI & Data Science firm), a Technology Consultant at Deloitte, and Acting Chief of Staff at Culture Trip (20M monthly visitors), reporting directly to the CEO. I hold an M.Sc. in Economics & Engineering from Solvay Business School (VUB), a B.Sc. from Ghent University, and did an Erasmus year at TU München. I speak six languages.

Read the AI SEO guideBy day I'm Head of Data & AI at Firgun Ventures and Lead AI Lecturer at Le Wagon. Alongside that, I work independently in four shapes: 1:1 consulting for specific decisions, Fractional Head of Data & AI for embedded leadership at startups, custom AI workshops and training for companies, and self-paced online courses. See Work with me for the full picture.
A single decision or review — book a consulting session. Ongoing data/AI leadership for a startup — Fractional Head of Data & AI. Running an AI workshop or training a team — AI training. Learning at your own pace — the AI SEO course.
