Sitruna review
Shortlist-ready for Marketplace / Retail Media, with the caveats below.
An Amazon marketplace operator with launch, inventory-aware performance monitoring, and market-expansion case work, but limited public pricing and thinner independent proof.
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.
Marketplace revenue and contribution-margin outcomesStrong
Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 20% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 8 · Strong 2 · Adequate 1 · Weak 1. The typical agency here scores Excellent, and 8 of them score higher than this one.
What this dimension measures: Measures profitable revenue, contribution margin, TACoS, new-to-brand, and organic halo—not sales or ROAS alone.
Scores low — Verified margin-aware growth scores 4-5; gross-sales vanity scores 1-2.
What we found — Case material reports marketplace accomplishments but public profit detail is limited.

ROAS — return on ad spend: revenue per dollar of advertising. Platform-reported ROAS overstates; independently measured ROAS is the honest version.
Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.

Scores low — Hands-on platform depth scores 4-5; generic PPC repackaged for Amazon scores 1-2.

Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 7 · Strong 4 · Adequate 1. The typical agency here scores Excellent, and 7 of them score higher than this one.
What this dimension measures: Owns keyword strategy, titles, bullets, A+ content, imagery/video, storefronts, testing, and review-safe conversion work.
Scores high — Measured listing lift scores 4-5.
What we found — Launch and listing work appear in the service and case model.
Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.
Operations, inventory and account healthExcellent

Measurement and incrementalityAdequate

What this dimension measures: Uses AMC, clean rooms, holdouts, new-to-brand, blended economics, and cross-channel measurement.
Scores low — Platform-attributed ROAS as the sole truth scores 1-2.
What we found — Performance monitoring is explicit; incrementality methodology is not.
ROAS — return on ad spend: revenue per dollar of advertising. Platform-reported ROAS overstates; independently measured ROAS is the honest version.
Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.
Marketplace and category fitStrong
Strong — 4 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 8% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 9 · Strong 3. The typical agency here scores Excellent, and 9 of them score higher than this one.
Scores high — Named results in the buyer's marketplace, geography, product category, price point, and maturity score 4-5.
Scores low — One-size-fits-all marketplace claims score 2.
What we found — Amazon specialization and cross-market launches support fit. That is the high band above, which is why it scored Strong.
Evidence: verified — checked against a named source you can open; the links under Sources below are where to check it yourself.
Client evidence and referencesAdequate
Adequate — 3 of 5 on this rubric’s scale, from Poor (1) to Excellent (5). This dimension carries 10% of the total score.
Benchmark — across the 12 other agencies evaluated in this discipline, this dimension runs Excellent 3 · Strong 7 · Adequate 1 · Poor 1. The typical agency here scores Strong, and 10 of them score higher than this one.
Scores high — Recent named cases plus verified reviews with sales, margin, TACoS, conversion, or operational outcomes score 4-5.
Scores low — Vendor claims without references score 1-2.
What we found — Named cases exist but independent review depth is limited in the reviewed sources. That is between the two bands, which is why it scored Adequate.
Evidence: vendor stated — the agency’s own claim, recorded as theirs rather than ours.
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 price, term, or ownership standard 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
Sitruna clears the threshold as a focused Amazon partner, particularly for UK or European brands expanding to the United States. Its Three Spirit case documents ongoing market insight, customer feedback, and performance adaptation rather than ads alone.
Hard financial metrics and independent review depth are thinner than at the leading candidates. A scoped launch or audit is safer than a long retainer until references, inventory planning, and account ownership are verified.
