Inventory Management

Recruited, validated, and continuously profiled proprietary panels — built to your exact target definition for repeated, longitudinal access to the audience that matters most to your business.

A custom panel gives clients on-demand access to a pre-recruited, continuously profiled subset of their specific target audience — without re-sampling from our general panel or competing with other clients for the same respondent pool.

QUELDEN SUPPLY LLC handles the full panel lifecycle: target audience definition, recruitment channel strategy, screening and qualification, profiling survey administration, compliance and consent management, ongoing re-profiling, and panel health monitoring (response rate, tenure, dropout rate).

Custom panels are ideal for clients with a defined, narrow audience — healthcare professionals, industry-specific buyers, brand loyalists, or geographic concentrations — where consistent, repeated measurement is more valuable than broad single-wave studies.

Panel access is licensed on an annual basis. Clients receive exclusive access to their panel and may field an agreed number of study waves per year. We guarantee minimum panel response supply, response quality standards, and profiling accuracy within contractual specifications.
