## About this market
Paris's B2B page holds different purchases under one label: a transformation program, an enablement program and an embedded build. Artefact's Bpifrance engagement took agentic AI from experiment to scale across 500 employees at the public investment bank, and what came out was more than 1,500 agents built by the business teams themselves. AI Sisters publishes mostly enablement—AI shows, promptathons and workshops for Accor, Samsung, JCDecaux and VINCI Facilities—and co-builds agents alongside the teams it trains. Preste is the builder: its project cards name the client, the stack and the build time, from a Jetson Orin Nano pipeline inside Greenbig's B:Bot recycling machine to a TensorRT model reading foosball games at 120 frames a second for Tecbak, though none reports an outcome or says whether the system still runs.

Pick the shape before the firm. If the goal is a workforce that builds its own agents, compare adoption evidence—how many people, how many agents, still in use after a year. If the goal is a model running on your own device, ask for the latency and accuracy it held in the field and who maintains it after handover.
