Purchase data tells you what happened. PanelVoice shows you why. By hearing directly from verified buyers, you can connect real attitudes to real behaviour and reveal the motivations behind growth, decline or shifting loyalty.

Because people often can’t recall what they bought - or notice when their habits change - we ground every response in verified trips, right down to SKU level. This gives you a clearer view of the factors influencing choice, and the confidence to size opportunities, validate strategies and guide decisions.

This evidence strengthens every trade conversation, helping you demonstrate your brand’s value with confidence and negotiate from a position of strength. It also clarifies your growth potential by showing exactly where new shoppers will come from and how to reach them.

Segmentation reveals the people, moments, and motivations that shape demand. By combining real purchase behaviour with attitudinal insight, we bridge the say do gap and identify distinct audiences you can target with confidence. Each segment is sized, profiled, and brought to life to show who your priority audiences are, what drives their needs and occasions, where the biggest growth moments sit, and how your brand fits into real routines, enabling smarter targeting, stronger innovation, and more effective investment.

Marketing only works when it moves shoppers. We link real media exposure to verified purchases to show who saw your activity, who bought afterward, and what truly drove incremental sales.

Using single source data, every impression and purchase comes into one clear view, revealing which channels reach priority shoppers, how different groups respond, and where performance lifts. This enables smarter planning, precise targeting, clear measurement, and faster penetration led growth.
