Cint solves respondent sourcing

Cint Exchange connects research buyers with survey participants through a sample marketplace. Buyers can use a self-service interface, integrate through an API or request managed services. For a team that already has a questionnaire but lacks access to its target audience, this is a different purchasing problem from choosing a survey editor. This review concerns the buyer side and is based on published documentation, not a live fieldwork test. Cint buyer overview

Targeting and managing a study

Exchange documents audience selection through demographic criteria and custom quotas, alongside feasibility and budget tools. During fieldwork, buyers can monitor progress and adjust cost-per-interview thresholds. The provider describes respondent-validation and fraud checks; those are supplier claims, not a guarantee that every collected answer is usable. Cint Exchange

A practical workflow is to define the eligible population, specify quotas, connect the questionnaire, review feasibility, launch collection and monitor accepted completes. Check the screening criteria before launch: a tightly defined population can change both feasibility and cost. Exchange also describes near-real-time distributions, demographic cross-tabs and downloadable reports. Confirm the required raw-data and report formats during setup. Exchange workflow

Theorem: a separate U.S. option

Theorem has published prices for two U.S. audience configurations, checked November 8, 2026:

These are per-response sample charges, not monthly software subscriptions. The launch checklist requires a survey built in Qualtrics, an interview shorter than 15 minutes, a mobile-optimized questionnaire and a correctly configured survey flow. Verify the audience definition and acceptance rules before committing a budget. Matching selected census demographics does not, by itself, prove that every result is representative of the U.S. population. Theorem details

Exchange pricing and integration

Exchange uses project-specific pricing under its rate card and order. The terms describe onboarding and credit processes; they do not establish one universal monthly subscription price. The commercial agreement should identify cost per interview, any transaction fees and the definition of a billable response. A free buyer plan or standard trial is not established by the pages reviewed. Buyer pricing terms

The Demand API is intended to automate project setup, recruitment and reporting inside another system. Cint's documented onboarding sequence includes reviewing the developer materials, agreeing a commercial CPI model with sales, building with integration support and then activating a study. This is useful for recurring research workflows, but it also adds technical work that a one-off buyer may not need. Demand API

Support and choosing the right route

Cint's buyer page lists support and managed-service options, while the legal terms define the order's subscription term and commercial responsibilities. Confirm project closure, reconciliation, support and cancellation arrangements before launching; a participant-sourcing order should not be assumed to have the same refund rules as a consumer software trial. Buyer overview, buyer terms

Our assessment: use Cint when sample access is the bottleneck. Compare Theorem for an eligible, broadly targeted U.S. Qualtrics study and Exchange for more configurable or integrated sourcing. Keep questionnaire quality, participant eligibility and response validation in the research plan even when procurement and fielding are automated.
