Sago review
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.
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.
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.

What other platforms say
Sago is operationally real, but recent respondent complaints are extensive, repetitive, and directly relevant to ethical fieldwork quality.
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
- 127 BBB reviews averaging 1.1/5
- Repeated alleged participant-payment delays
- Unreachable or scripted support complaints
- Sample trust and brand-risk implications
How it scored
Research design and methodological rigor
The company has formal research and data-quality processes, but execution concerns reduce confidence.
Sampling and respondent quality
Widespread incentive and support complaints create attrition, trust, and response-quality risk.
Qualitative and quantitative capability
Global qualitative and quantitative infrastructure is real.
Analysis, synthesis and actionability
Capability is marketed, but participant-side execution failures can compromise inputs.
Client evidence and decision outcomes
Named client references exist, but the adverse respondent evidence is more current and voluminous.
Data privacy, ethics and AI disclosure
Repeated complaints about incentive handling and unreachable support create an ethics and governance concern.
Domain, audience and market fit
A global network supports many markets and audience types.
Pricing, timeline and research ownership
Participant complaints repeatedly allege timelines extending beyond promised payment windows.
What we could not verify
- Whether 2026 payment and support controls have been independently remediated
- Client-side fieldwork rejection and attrition rates
