Participant recruitment has several jobs: finding people with relevant experience, checking study fit, scheduling participation and administering incentives. Choose a service against those jobs before comparing panel size or a headline speed claim.
Official pages checked October 12, 2026. These are published workflow descriptions, not a hands-on quality test or traffic ranking. Confirm audience feasibility, current pricing and policies directly. A recruitment service does not replace your research method.
| Need | What to investigate |
|---|---|
| Reach people outside your customer base | Panel coverage for the exact role, activity and location; expected screening burden. |
| Recruit existing customers | Permission to contact, contact rules, scheduling and panel management. |
| Specialist experience | What verification checks cover and what your screener still needs to establish. |
| Predictable operations | No-shows, replacement eligibility, incentive handling and complete fees. |
