Overview
Some audiences cannot be bought from a panel: a handful of prescribers of a rare therapy, plant engineers in one industry, or investors with significant assets. Research and Metric specialises in recruiting hard-to-reach audiences like these, using targeted sourcing and careful verification.
We tell you early what is realistic, then work every route available: client lists, professional networks, referrals and specialist partners.

FAQ
Frequently asked questions
Cannot find your answer? Ask our team or email contact@researchandmetric.com.
What makes an audience hard to reach?
Small population size, seniority, gatekeepers, or a rare behaviour such as using a specific therapy. These audiences are rarely available on general panels.
How do you verify specialists?
We confirm role, employer and decision authority by phone, and check licence and current practice for healthcare professionals before any interview is booked.
Can you combine our client list with your own recruitment?
Yes. We often contact client-supplied names alongside independent recruitment to reach people the list does not cover.
What if the audience is too small for our quotas?
We say so at feasibility and suggest options, such as wider markets, adjusted quotas or a different method.
