dunnhumby is the global leader in Customer Data Science, empowering businesses everywhere to compete and thrive in the modern data-driven economy

When businesses are built around the people they serve, the world becomes a better place – and every Customer experience becomes more meaningful. It’s why Customer data has never been so important. But to maximise its potential and use data to inform smarter decisions, businesses need the ability to interpret and act on Customer insight at scale and in real-time.

dunnhumby empowers brands and retailers to do this through more relevant and engaging experiences. We help our clients build Customer First strategies with cutting edge solutions, and we never stop innovating – ensuring the decisions clients make encourage Customers to return, time after time. We analyse data and apply insights from nearly one billion shoppers across the globe to create personalised customer experiences in digital, mobile, and retail environments. Our strategic process, proprietary insights, and multichannel media capabilities build loyalty with customers to drive competitive advantage and sustained growth for clients.

We always put the Customer First. Our mission: to enable businesses to grow and reimagine themselves by becoming advocates and champions for their Customers.
