About this list
Enterprise AI consulting is where the strategy-to-delivery boundary decides the value of the fee, and the agencies here sit at every point on that line. At one end, Artefact publishes more than a hundred client pages and its Bpifrance engagement put AI agents in front of 500 employees at a public investment bank—consulting that ends in adoption, not a deck. Faculty's NHS AI Lab work is validation infrastructure, the layer that decides whether a clinical model is allowed to matter. appliedAI takes enterprises from maturity assessment through EU AI Act readiness to production, and Wavestone attaches AI delivery to a governance practice that names DORA, NIS2 and the AI Act.
The question that separates these firms fastest: where does the engagement end? Some stop at the roadmap, some at the pilot, some operate what they build. All three answers are legitimate purchases—but paying delivery prices for roadmap work is the most common enterprise procurement mistake in this market, and the documented-client counts on each card show which firms have shipped past the deck.

Expert Insight
Why enterprise fit matters for AI Consulting
Enterprise AI fails at the surroundings, not the model: procurement, security review, model documentation and adoption budgets decide outcomes, and an agency that has cleared them before will price and plan for them unprompted.
Reference checks work differently at this scale—an agency with two documented enterprise engagements can name a buyer who survived the same internal scrutiny yours will apply.
The pilot-to-production gap is widest here: ask for case studies that describe operations and handover, because a proof of concept that never shipped is the modal enterprise AI outcome.
