## About this market
Custom AI development means three different purchases in France, and this roster carries all of them. The narrowest is deep engineering. Preste works across computer vision, anomaly detection, document processing, conversational agents and molecular design, and is an NVIDIA embedded software partner building on Jetson platforms, which makes it the only listing here that reaches the edge device. Serokell pairs functional-programming engineering with predictive maintenance, computer vision and language systems from a Paris office open since 2015, and FFFACE.me builds virtual try-on and AR mirrors for fashion and beauty brands. The second purchase is a data platform with models on top, and Lyon supplies most of it: AVISIA since 2007, ActinVision and Datalyo since 2014, then DataGenius, Qweri, Flowt, and Yield Studio building custom applications for mid-sized French companies. The third is the consultancy tier—Artefact, Converteo, Wavestone, AI Sisters, Upscale Paris—which will build, but sells the program wrapped around the build. Automato, Mozza and McLeuker sit outside all three, on internal tooling, product audits and fashion-tech.

Where rates are published at all they fall into two bands: Preste and Serokell at €45–85/hr, FFFACE.me and Yield Studio at €85–130/hr, everyone else on request. Sort by size fit before capability, because a small Lyon practice and a 2,500-person consultancy will not answer the same brief or price it within the same order of magnitude. Then make stack specificity the test. Ask which models, in whose cloud account, with what in the handover package—and treat vagueness as an answer in itself. Automato's published work names no model, framework or provider anywhere, which matters far more for a build than it does for a workflow.
