« Un agent n'a pas de bon sens » : ce qu'ADEO et Decathlon ont compris de l'ère agentique
Editorial article **SFEIR AI** published on sfeir.com on **September 6, 2026** (~9,000 characters, seven sections, two sources noted). It recaps an episode of the **DataGen** podcast hosted by **Robin Conquet**, recorded at the **Dev Summit** co-organized by **Adeo** and **Decathlon** (Lille, **May 26-28, 2026**, more than **2,000** attendees), with **Matthieu Grymonprez**, who heads digital, tech, and data at Adeo (Leroy Merlin, Weldom, Obramat), and **Romain Taillade**, Global CTO of Decathlon. Three takeaways. **(A)** The platformization carried out over five years to absorb Leroy Merlin's marketplace (**60,000** in-store references, several million online) and Decathlon's expansion (**more than 50** countries) was not aimed at agentic AI, but forms its foundation: *"the platform built the muscles, the age of intelligence builds the nervous system."* **(B)** Three named workstreams — the development **harness**, zone-based **security** across the IT system (zero agentic activity on payment, the checkout flow, and the supply chain), and **data semantics**, tackled by vertical and where Adeo admits it is in debt. **(C)** A precedent the group paid for: self-service BI produced more than **150,000 dashboards** before the return to certified data products. Grymonprez's framing sentence holds it all together — *"an agent has no common sense"*: it applies the definition as given and accelerates disorder wherever it is lacking. Continues, with the same executive, [[alafrench-grymonprez-adeo-ia-agentique-grands-groupes-2026-06-18]].
