Supplement SierraTec Audience when the study needs more reach
External sample is an optional extra source. SierraTec sources it on your behalf through approved partners for hard-to-reach groups; the provider's cost and SierraTec's fee are shown before launch and settled when the project is reconciled.
No implied partnerships
The public site does not display provider logos or claim integrations until a commercial/API relationship has been approved and configured.
Provider qualification
Review coverage, sourcing practices, participant treatment, quality controls, privacy terms, APIs, security, pricing, and operational support before activation.
Source-level transparency
Retain provider/source IDs, incidence, quota, termination, quality, cost, and reconciliation metadata for methodology and vendor management.
Automatic or manual routing
Enterprise workspaces may allow SierraTec to select an approved supplier or let authorized researchers choose from configured providers.
SierraTec-owned supply stays first in the default routing order
| Priority | Source | Use | Availability |
|---|---|---|---|
| 1 | SierraTec Audience Network | Default first-party participant source | Core |
| 2 | Customer-owned audience | CRM lists, panels, communities, employee/student/customer populations | Customer controlled |
| 3 | Approved external sample | Supplement unmet or specialist quotas | Contract/configuration required |
Provider cost + transparent SierraTec orchestration
External sample shows the provider's cost separately from SierraTec's orchestration fee, currently 10% of provider cost.
Provider pass-through
Store quoted CPI, incidence assumptions, minimums, taxes, and provider-specific adjustments.
Orchestration fee
Cover feasibility routing, quota control, quality review, reconciliation, consolidated billing, and support.
Accepted-complete settlement
Track quality exclusions and replacement/credit requests before final provider settlement where contracts permit.
