Real respondents.
Verified identity.
Lower cost.

The problem

Your data quality problem
starts at recruitment

Bots, AI agents, and duplicate accounts have become a structural problem in online research. Studies that would have sailed through peer review a few years ago are now getting flagged — or worse, producing results that don't replicate.

Standard panels like Prolific and CloudResearch have quality controls, but their verification is based on platform accounts and behavioral signals — not identity. Anyone can create an account. Motivated participants game attention checks. And the same person can complete your study multiple times across panels.

For academic research, this isn't just an inconvenience. It's a validity threat.

"The question is no longer whether your instrument is well-designed. It's whether the people completing it are actually people."

Verification

Four layers of verification,
not just one

Most panels stop at behavioral signals. Onkoru's verified panel stacks four independent layers — so you know who is completing your study before the first response comes in.

01
Government-Issued ID Verification
Every respondent in the panel has verified their identity against a government-issued document — passport, driver's license, or national ID. This is not email verification or phone verification. It's identity verification. A bot cannot pass it. A duplicate account cannot pass it.
Identity layer
02
Deduplication & Uniqueness
Each verified identity maps to exactly one panel account. No respondent can complete a study twice, appear in multiple panels, or re-register under a different email. The panel enforces one person, one account — permanently.
Integrity layer
03
Bot & AI-Agent Screening
Respondents are screened at onboarding and monitored at the session level for behavioral signatures consistent with automated completion — response latency patterns, cursor behavior, answer consistency, and open-end response quality. AI-generated text is flagged and reviewed before data is released.
Behavioral layer
04
Longitudinal & Recontactable
Because respondents are identity-verified and deduplicated, the panel supports longitudinal designs and multi-wave studies with confidence. You can recontact the same verified individuals over time — not hope that the same people show up again on an open panel.
Continuity layer

Population

General population &
specialized subgroups

The panel spans a broad general population with curated subgroups for studies requiring specific professional, demographic, or experiential characteristics.

General

U.S. General Population

Nationally representative samples. Demographic quotas on age, gender, income, and geography. Suitable for most consumer, behavioral, and social research designs.

Professional

Employed Adults & Professionals

Working adults by industry, role, seniority, and organization size. Managers, executives, knowledge workers, healthcare professionals, educators, and more.

Specialized

Targeted Subgroups

Custom screened populations by diagnosis, behavior, consumption pattern, life stage, or domain experience. Consult on availability before designing your study.

Use cases

When the verified panel
is the right call

01
Publication-track research requiring defensible data quality
When reviewers will ask about bot filtering, duplicate respondents, or data integrity — having government-ID verified participants is the most defensible answer. No reviewer can question the humanity of your sample.
02
Multi-wave and longitudinal designs
Studies that require the same person to respond at T1, T2, and T3 — with confidence that it's actually the same verified individual, not someone who matched a demographic profile on an open panel.
03
Sensitive topics or clinical-adjacent research
Studies involving mental health, medical history, financial behavior, or other sensitive domains where response authenticity and participant identity matter beyond standard data quality thresholds.
04
Niche or hard-to-reach populations
When your study requires a professional background, specific diagnosis, or demographic characteristic that is rare in general panels — and you need confidence the screening is real, not self-reported without verification.
05
Replication studies
When you're replicating an existing finding and need to rule out data quality as a confound — verified participants give you a clean baseline that standard panels can't provide.
