Julien Poncelet

Julien likes using technology to solve problems, and in particular building systems (data, tools and processes) that help organisations work better. He started out in research, with a joint PhD in Financial Economics from ULiège and Maastricht University, after an MSc at Solvay. He then joined Oliver Wyman in London, where he led retail analytics work and built in-house AutoML tooling along the way. He later headed data science at Redkite and led data strategy and AI programmes at Artefact.

Since 2024, he has worked mostly on data platforms and AI strategy. He enjoys working on both the technical and the business side of a project, and still writes code himself.

In his spare time, Julien is a true board game geek, plays the piano, and reads science fiction.

Julien will join element61 in November 2026.
