Sago review
Measured against the Market Research rubric, with specific adverse findings below and a source on each one.
A real global research supplier with formal data-quality materials, but 127 BBB reviews averaging 1.1/5 allege delayed or missing participant payments and weak support, directly threatening trust and respondent quality.

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.

Verdict
CUT pending demonstrated remediation. Sago is a substantial research company and publishes ESOMAR-style sample and validation materials. The adverse evidence is too material to hand-wave: BBB lists 127 customer reviews averaging 1.1/5, with repeated 2026 complaints about delayed incentives, inaccessible support, and missing payment records.
Participant treatment is not peripheral—it affects recruitment, completion, honesty, attrition, and brand risk. Reconsider only with recent payment-SLA audits and client references proving fieldwork quality.
