All of a sudden, everyone is an «AI agency». The trouble is that the label covers wildly different things: teams using AI to do their usual work better, software factories in disguise, and people who learned to write prompts three months ago. If you're a CMO or a brand owner, the question is not «do they use AI?» — everyone does now. The question is do they have judgment?

Let's get straight to the point. Here are the six filters we'd use to choose, and that help you tell a partner from someone selling hype.

1. Strategy before tools

If the first meeting opens with outputs —images, videos, «look what it generates»— before anyone understands your business, your category and your competitive tension, walk. AI doesn't start with the asset; it starts with the decision. Without a diagnosis, speed just gets you to the wrong place faster.

2. Human judgment at the helm

The healthy formula is simple: AI-powered, human-led. AI brings speed and scale; judgment —which idea is worth it, what tone, what gets cut— is human and senior. An agency selling you «fully automated» is selling you the problem, not the solution: in markets flooded with synthetic content, what's scarce isn't production, it's judgment.

3. Not a software factory

There are two different animals: a software factory with creative pretensions, and a creative agency with augmented technical capabilities. For a brand, the second is what matters — technology serving the idea, not the idea subordinated to a tool demo.

4. Proof, not promise

Ask how they validate before you put money into media. If the answer is «trust our experience», half of it is missing. You can now pre-test a campaign —with synthetic audiences and brand personas— before investing. It doesn't replace the market, but it lowers the risk of an expensive mistake.

5. Integration, not islands

The value isn't in a standalone tool; it's in the thread that connects research → strategy → production → media. If each stage lives with a different vendor, you end up being the integrator. A good partner holds the brand's judgment end to end.

6. Saliency and performance, not «fast and cheap»

AI made producing a lot trivial. So the differentiator stopped being volume and went back to what it always was: making your brand noticed and remembered. If an agency seduces you only with «more pieces for less money», it's pushing you into the sea of sameness. Cheap often ends up expensive.

In one line

AI doesn't replace judgment: it amplifies it. Choose a partner, not an output vendor. That's how we work —with challenger brands and with mid-sized and large companies—: AI inside, human judgment at the helm, and the brand always as true north.
