Before you compare consultants, work out which of these four things you are actually buying.

"AI consultant" is not a profession with a definition. It is a label covering at least four jobs that require different skills, cost different amounts and fail in different ways. Almost every disappointing engagement we have seen described publicly reduces to the same error: a business bought one of these and needed another.
What they do: work out where AI could matter in your business, in what order, and what it is worth. Output is analysis, a prioritised roadmap and usually a board-ready case.
Hire them when: you have budget and executive attention but no agreement on where to point them, or you need to persuade a board.
How it fails: you receive an excellent document and nothing changes. Guard against this by requiring at least one working artefact — a prototype, a mapped and instrumented process — as part of the deliverable.
What they do: build the thing. Connect systems, write the automations, wire the models in, put it into production. Frequently working in tools like Make.com, n8n or Zapier, or writing code directly.
Hire them when: you already know what you want built and can describe the process precisely.
How it fails: they build exactly what you asked for, and what you asked for was the wrong thing. A good implementer pushes back on the brief; a cheap one does not.
What they do: raise the capability of your existing staff so they can do this themselves. Workshops, prompt libraries, internal standards, an AI champion in each team.
Hire them when: your problem is a hundred small inefficiencies spread across the business rather than one big automatable process. This is more often the right answer than people expect, and it is usually the cheapest of the four.
How it fails: everyone enjoys the workshop and reverts within a fortnight. Insist on something durable — written standards, a shared prompt library, a named owner.
What they do: establish what is allowed. Data handling, vendor assessment, human review requirements, audit trails, regulatory compliance.
Hire them when: you are in a regulated sector, handling personal or client-confidential data, or operating where the EU AI Act applies.
How it fails: it gets skipped, and then it gets discovered — usually by a client, a regulator, or a journalist. This is the one people cut from the budget and then wish they had not.
| If your honest position is… | You probably need… |
|---|---|
| "We know AI matters but have no idea where to start" | A strategist — but buy a small, bounded audit first |
| "This specific process eats twenty hours a week" | An implementer |
| "Our team uses ChatGPT badly and inconsistently" | An educator |
| "Legal or compliance has questions we cannot answer" | A governance specialist |
| "We tried something last year and it quietly died" | An implementer and an educator — the tool was probably fine and nobody's job changed |
Plenty of good consultants genuinely do two of these well. Very few do all four, and anyone claiming to is describing a team, not a person — which is fine, as long as you know it and know who on that team is doing your work. Ask directly: which of these four is your strongest, and who would you bring in for the others? A confident, specific answer is a good sign. A claim to be equally excellent at all four is not.
No consultant in any of these four categories can make the decision about whether to change how your business works. They can tell you what is possible, build it, teach it and keep it legal. The decision that a job should be done differently is yours, and it is the part that actually determines whether any of this returns anything.
