What we do

We use data and science to delight customers and build loyalty

dunnhumby is the world’s leading customer science company.

What does that mean, exactly? We know customers. And we help companies know them, too. In fact, we can help you know your customers so well that you’ll meet their current needs, predict their future ones, and keep them coming back, again and again.

WhatWeDoDiamond

how we do it

Analysing data from more than 400 million customers worldwide, we uncover valuable INSIGHTS: what customers want, where they want it, and how much they’re willing to pay for it.

Then we turn those insights into action, PERSONALISING THEIR EXPERIENCE, in and out of store, online and off, before, during and after, earning a lifetime of loyalty.

Additionally, we use these insights to TRANSFORM OUR CLIENTS into customer-first organisations.

By putting best customers at the centre of every decision, our broad, programmatic approach delivers MEASURABLE VALUE, competitive edge, and even more customer data to fuel ongoing optimisation, setting you up for long-term success.

Clients

The passion and ambition we share with dunnhumby is that we both believe that to succeed we must put the customer at the very heart of our business. The invaluable customer insight we gain from them, both in the UK and internationally, means we can tailor our offer according to what our customers want and need, wherever they may be.
