Operating stance
- We are a sample supplier—we do not claim third-party marketplace panels as our own assets.
- Primary strength is overseas markets—especially Southeast Asia, India, Japan/Korea, plus selected Europe and Americas—with Hong Kong / Taiwan as a regional hub. Mainland China is a smaller, selective share of reach.
- Figures in this book are indicative monthly inviteable supply, not guaranteed completes by country.

Quality & technology
How we protect fieldwork
Registration & uniqueness
Double opt-in when member accounts are live. Device / session controls and duplicate prevention before reward eligibility.
In-survey signals
Speeding, straight-lining, and inconsistent response patterns reviewed against study rules.
Marketplace alignment
When supplying into an exchange or buyer platform, we follow their fraud, reconciliation, and traffic rules in addition to our own.
Routing stack
Fieldwork-capable redirects for complete / terminate / overquota / quality outcomes with session identifiers for reconciliation.
Profiling dimensions (typical)
- Gender, age, region / city tier
- Education, employment, industry
- Household composition
- Income bands (market-local)
- Device & mobile OS
- Category interest flags
