How to choose an AI agency

Choose an AI agency on what still runs six months later, not on the demo: that looks the same at almost every agency. In the 2024 BCG survey, 26% of companies were already generating value from AI (1,000 executives). This buyer guide gives you seven questions to hear the difference before you sign. There is no ranking in it; you draw the conclusion.

Seven questions to ask any AI agency

Ask them in the first conversation, before there is a quote. Next to each question is what a good answer sounds like.

1. Which project did you advise against?
A good answer is a concrete example with a reason. An agency that has never said no will not say it to you either.
2. Who will write the code?
You want a name, and that person also sits in the meetings. At many agencies a senior sells and a junior builds. Ask who picks up the first ticket.
3. Is the price fixed up front?
You want an amount and an end date in writing. An hourly rate with no ceiling puts the entire risk on you.
4. Who maintains this once you are gone?
You want a name inside your own organisation, plus the agreement that this person builds alongside. Otherwise you are buying a dependency.
5. How is the result measured?
You want one number agreed up front: hours, lead time, error rate. "More efficiency" is not a measurement.
6. What happens to our data?
You want to know where the model runs, what is retained and what the EU AI Act means for your use case. "That is secure" is not an answer.
7. What is likely to go wrong?
You want two or three risks that are about your situation. An agency that only names opportunities has not understood your problem or is holding something back.

Three kinds of AI agency, and when each fits

Three kinds of business sit behind the AI agency label. Each fits a different question.

The marketing or digital agency that added AI
Strong on content, campaigns and customer experience. Choose this type when your question is about marketing, and another when the answer has to land in your ERP or your operation.
The software studio
Strong at building. Choose this type when you already know what needs to exist and mainly lack capacity. If you are still working out which problem to solve, it is too early.
The consulting firm
Strong on analysis, buy-in and governance, often in large organisations with many stakeholders. If you want something working within a quarter, expect a second party to build it.
An AI agency that chooses and builds
What you are usually after: a party that first chooses which use case deserves production and then builds it too. Choosing without building produces a report, building without choosing a pilot nobody uses.

My own answer to question one

Anyone who asks that question should answer it too. I once advised waiting with a GenAI product; building continued anyway.

Since then, a no from me goes on paper, with the reason attached, before a single euro goes into building. Advice that nobody writes down, anybody can overrule.

When I am not the right fit

I work alone, from Rotterdam, with your team. That makes me the wrong party for a number of questions.

If you need a team of ten supplying capacity for a year, choose a software house. If you want a brand campaign with AI in it, choose a creative agency. And if the answer is already fixed and you only want confirmation, I will not make you happy.

I fit when you have already started with AI, it is stuck at the demo, and you want someone who first says what to stop and then builds what remains.

Frequently asked

What does an AI agency do?

An AI agency helps companies get AI into their daily work: choosing use cases, building systems and arranging who maintains them. Some agencies only advise, others only build. You see the difference in where they stop: at the advice, at the demo, or only when the system runs in production and someone inside your company runs it.

What should you look for when choosing an AI agency?

Four things: who actually builds, whether price and end date are fixed up front, who maintains the system once the agency is gone, and which project the agency once advised against. Give the demo little weight, because almost every agency shows the same one.

What does an AI agency cost in the Netherlands?

What other agencies charge I do not know, so I am not going to invent that figure. My Scan costs from €1,995 ex VAT for about a week. Ask every agency for a fixed price per result, so you know what you are comparing. My prices per format are on the AI consultancy page.

Large consulting firm or small AI agency?

You buy a large consulting firm for analysis, buy-in and governance in a politically complex organisation. You buy a small agency because the people you talk to also do the work. Choose large when the decision is the problem, and small when execution is the problem.

Does an AI agency need to be nearby?

For the analysis work, no: that runs fine remotely. For working sessions, yes. Three hours in a room with the people who do the work beats ten videocalls. So look for an agency that comes to you; being around the corner is not required. I work from Rotterdam across the Netherlands.

And if your conclusion is: do not build this?

Then that is the deliverable, and you pay for it. If my verdict is do not build, I will not build it either, not even if you insist. If another party is better suited, I say which one. That costs me the engagement. Every yes I have to deliver myself, at a fixed price in four weeks; that is why my no means something.

How do you tell whether an AI agency really builds?

Ask for something live that they built themselves, and who maintains it. Ask what broke and how it was fixed. An agency that builds answers with detail; an agency that resells stays on process. What I built is at Signal Match and Business Boosters.

How to use these questions

Ask three agencies the seven questions and put the answers side by side. Anyone without a concrete answer to question one or question seven drops out. From what remains, pick the type that fits your question.
