Merkle review
Shortlist-ready for AI Marketing, with the caveats below.
Enterprise-scale AI, data, CRM, and customer-experience implementation with unusually concrete personalization and efficiency outcomes.
No published price we can link to. We do not estimate one — ask on the call, and see the pricing-transparency line in the scores below.
How it scored
Every dimension is scored against this discipline’s published rubric. Open one to see the claim it was scored on, what the rubric measures there and how much it weighs, and where the evidence came from.
How we scored this
We read the agency’s public record first-hand — its site, pricing, case studies and independent reviews — and score what is checkable: what is published, not how it is phrased. There is no keyword counting or sentiment scoring. The label is a judgment on those facts, which is why each dimension shows the fact that decided it, the band it was judged against, and the sources — so you can check the call, and tell us if you think it is wrong. The full method, and who pays, is on how we vet.

Contract & pricing transparencyNot disclosed
Not disclosed — 1 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). Nothing was published about this, so it scores at the bottom of the scale — that is a finding about what the agency discloses, not about the quality of its work. This dimension carries 5% of the total score.

Scores high — Public pricing anchor and month-to-month or short terms score 4-5.
Scores low — Opaque 'contact us' bespoke-only or long lock-ins score 2.
What we found — No useful public pricing or contract detail located. That is what the low band describes, and nothing published resolves it.
Evidence: unknown
Stronger here: Streamline Agency scores Strong on the same dimension.
Verdict
Merkle is a strong enterprise option when AI must connect data, CRM, media, and customer experience rather than produce isolated content. Currys evidence shows operational and conversion impact at scale. Procurement should still verify the named delivery team, model governance, and budget because public pricing is absent.
What you can do next
Koolav can make the introduction and handle the back-and-forth, or you can go straight to the agency.
