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.
Marketplace revenue and contribution-margin outcomesExcellent
Excellent — 5 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 20% of the total score.

Pricing, account ownership and commercial termsNot disclosed
Not disclosed — 2 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 6% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Strong 3 · Adequate 3 · Weak 5 · Poor 1. The typical agency here scores Adequate, and 6 of them score higher than this one.
Scores high — Clear retainer/revenue-share terms, disclosed media or reseller markups, client-owned marketplace/ad accounts, asset ownership, and short exits score 4-5.
Scores low — Seller-account control or opaque percentage fees score 1.
What we found — No public pricing or standard account-ownership term was located. That is what the low band describes, and nothing published resolves it.
retainer — a fixed monthly fee regardless of hours or output — predictable, but worth tying to a defined scope.
Evidence: unknown
Stronger here: Sequence Commerce scores Strong on the same dimension.
Verdict
Tinuiti is the strongest option for a scaled brand that needs Amazon plus multiple retail-media networks and sophisticated audience measurement. Amazon's own case library validates Advanced Partner status and use of AMC, DSP, streaming video, brand studies, and downstream behavior analysis.
The firm is likely expensive and may be overbuilt for a small seller. Define incrementality, contribution margin, new-to-brand methodology, and data portability before letting attributed-sales dashboards drive the relationship.

What other platforms say
Strong enterprise media and measurement evidence; commercial accessibility for smaller brands is unclear.
These are other platforms' numbers, not ours. We report them because they are part of the picture, and we do not average them into our score — our score comes from the published rubric above.
Red flags
- Likely enterprise economics
- Attributed-sales metrics can overstate incrementality unless governed
What we could not verify
- Minimum media spend and agency fee
- Standard data, creative, and account ownership language
