Make the call on CATI research
Interviewing a specific region or demographic? Sometimes a call is all it takes to reach your selected market. CATI research is one of our specialties, with years of experience collecting phone data.
When online isn’t an option
F2F and field interviews are sometimes the only way to reach your audience, especially if there’s products to test or taste. Our field team are experts at finding the right people, in the right place for your needs.
Stress-free data collection
A 75-seat award-winning CATI call centre based in the UK. A field force of over 500 field interviewers and in-house co-ordinators. A 30,000 strong UK online panel. All ran and managed in-house by Walnut, meaning there’s no other agencies. We are the one-stop-shop for stress-free data collection.
