Ten AI agencies the top-ranking lists name most, each checked on its own website. Then the checks to run before you sign with any of them, us included.
The short answer, as of 30 September 2026
The AI agencies the ranking lists name most today are NoGood, WEBITMD, Impression and Major Tom, in that order.
We read 18 lists of the best AI agencies and counted how often each agency is picked. NoGood leads, named by five lists it did not write. Below are the ten agencies named by two or more lists, each checked on its own website on 30 September 2026.
We put ourselves last, as our own entry. None of the lists we read names us, so the rule that ranks everyone else puts us at the bottom. We would rather say that than rank ourselves first.
No agency here is best for everyone. Most of them say they serve brands, software firms or online shops. If you run a service firm, the order matters less than the checks further down. They tell you what to ask any agency before you sign, and they work on us too.

Counted on 30 September 2026. A list an agency wrote about itself does not count, and nor does a directory.
How we built this list
We counted who the ranking lists pick, then checked every agency on its own website. Here is the rule, so you can check it.
On 30 September 2026 we read 18 lists of the best AI agencies. They came from Google’s first page in the UK and the US, and from the lists Perplexity cited when we asked it who to hire.
We counted how many lists pick each agency. A list an agency wrote about itself does not count for that agency. Directories do not count either, because agencies sign up to appear in them. Every agency picked by two or more lists is here, most picked first, with ties in alphabetical order.
One agency met that bar and is missing. Matrix Marketing Group is named by two lists, but its website would not load when we checked, so we could not confirm a single fact about it.
Every fact below comes from the agency’s own website that day. Where a site was silent, we left the point out.
The four agencies the lists name most
Each is picked by three or more lists: two American agencies, one British and one Canadian.
Four more, each picked by two lists
These four tie on two lists each, so they appear in alphabetical order. Every one of them is picked by at least one UK list.
The last two, and our own entry
Two more tie on two lists. Our entry comes last, because no list picks it.
Which agency fits which buyer
The order shows who the lists talk about, not who suits you. Match each agency to the buyers it says it serves.
Big brands will find Keenfolks and Viral Nation describing work for global and enterprise brands, and VCCP showing campaigns for O2 and Cadbury. Brainlabs says it is built for marketing leaders.
Software and B2B companies are named as buyers by NoGood, Single Grain and Brainlabs. WEBITMD is the only one of the ten that says, in those words, it serves small and medium-sized companies.
If you want a UK agency, Found, Brainlabs and VCCP are in London, and Impression is in Nottingham and London.
If you run a service firm, such as a law practice, an accountancy or a consultancy, notice one thing. On the pages we read, none of the ten names service firms among its sectors. That does not rule any of them out. It means your first question to each one is simple: show me a client like me, with a name and a date.
The four kinds of AI agencies, and which you need
AI agencies come in four kinds, and the words “AI agency” can mean any of them. Knowing which one you need crosses most names off before your first call.
To see what an AI marketing agency does day to day, and what you get back, read our plain guide.
AI agencies in the UK and London
Four of the ten are British, and three of those are in London. Here is where each one says it is based.
Found is on Hatton Garden in London, with an office in New York. Brainlabs is at the White Collar Factory in London, with offices in Toronto and New York. VCCP is on Berners Street in London, with offices in Madrid, New York, Prague and Singapore. Impression is in Nottingham, with offices in London and New York.
The UK lists we read also picked agencies that fell short of our count. PUSH, Open Partners, Croud, Koozai and ClickSlice are each picked by one list they did not write. PUSH and Open Partners each rank themselves first on their own lists, which is common, as we explain below.
For a UK service firm, a London address matters less than proof. Ask whether the agency has done this work for a business like yours, and whether you can check it.
How to choose an AI agency: five checks
They work on any agency, us included. Ask them on the first call.
Be wary of anyone who promises an exact return on investment before they have seen your numbers.
What AI agencies cost
Most of the ten print no price. You find out on a call, so go into that call knowing your own numbers.
Of the ten, only NoGood states a figure on the pages we read. It says on its own homepage that its average retainer is above $20,000 a month. The other nine show no price there. Single Grain offers a free growth audit.
We publish our prices on our pricing page, so you can see them before you speak to us.
Price alone tells you little. Before any call, work out what one new client is worth to you over a year. Then list the work you want off your team each week. Compare agencies on how much of that list each one will take on, and how each will show you it is done.
Our guide to what an AI agency costs, and whether it is worth it, goes through this step by step.
How to read any best-of list
Most best-of lists are written by someone with a stake in the answer. Four checks show how much weight to give one.
That is why we put ourselves last and said so.
Judge us on your own business
Every agency on this list will tell you it is good. The fairest test is what an agency finds in your own business.
Put your website into our free audit. We ask ChatGPT, Gemini and Claude about your business, then show you what they say and what we would fix first. Then judge us on the five checks above, the same way you would judge anyone else on this page. If you would rather talk it through first, start with a free consultation call.
