yellowHEAD review: the AI analyses your screenshots. Avoid paying 130 people to run it.

yellowHEAD is the agency that brings artificial intelligence to the sales call. Its proprietary technology analyses the design elements of app store creative, colours, characters, layouts, and predicts which combinations will convert best. For a visual category like gaming, that is a legitimately useful capability, and the agency has been building it since well before AI was on every deck. I want to be clear about that before I tell you why I would not sign the retainer.

The first thing to understand is what yellowHEAD actually is. It is a performance marketing agency. Paid user acquisition is the core business; SEO, ASO and creative sit around it. More than 130 people, offices in Israel, New York, Cyprus and Poland. When you buy ASO from a company shaped like that, you are buying a slice of a media agency, and a media agency’s economics are built around spend. Organic work is the small, slow, fixed-fee corner of a business whose big numbers come from managing budgets.

The second thing is what the AI does. It scores creative. It tells you that a screenshot with this colour palette and that character placement is likely to convert better than the alternative. Useful. But scoring is the cheap part of creative optimisation. The expensive part is deciding what claim your first screenshot should make, producing the variants, running a clean test, and having the discipline to change one thing at a time. That is human work, it is done by a strategist and a designer on a roster, and no prediction model replaces it. The AI is the demo. The roster is the delivery.

The third thing is scale. An agency of 130 people has a cost base of 130 people. Engineers maintaining the model, media buyers, account managers, a sales team working three continents, offices in four countries. Every retainer, including an organic-only one, carries a share of that. On a typical fee, something like a quarter reaches the people rewriting your metadata and building your screenshot tests. The rest funds the machine that built the AI and the machine that sells it.

Compare that with hiring one consultant. I do not have a prediction model. I have a thousand audited listings and a method: the teardown, the rewrite, one controlled creative hypothesis at a time, the handover. You talk to me, the scope is fixed, and the fee is a fraction of a year at a large performance agency, because nothing on the invoice is engineering, media or offices. When we finish, your team can run the next test without me, and without a licence to anyone’s AI.

In fairness: if you are a large gaming or consumer app with a serious paid budget and a continuous creative pipeline, yellowHEAD’s combination of UA, creative and AI analysis is a coherent offer and the technology is real. If you are here because your organic listing is underperforming, the AI is not the bottleneck. Judgment is. Send me their proposal and I will show you what the ASO work costs without the agency wrapped around it.
