Tesco’s consumer insight company Dunnhumby has signed a deal with US department store retailer Macy’s.

Dunnhumby, which is majority owned by Tesco, will analyse Macy’s sales data with a view to increasing turnover and customer loyalty at the retailer.

The deal could lead to the creation of a loyalty scheme at Macy’s similar to the Tesco Clubcard, which was an initiative launched by Dunnhumby.

Dunnhumby USA, a joint venture between Dunnhumby and US retailer Kroger, will analyse the data from 850 Macy’s department stores.

Dunnhumby USA provides similar services to US retailers including Kroger and Home Depot. It tracks the shopping habits of 250,000 consumers in the country.

In Europe, Dunnhumby works for Casino and manufacturers such as Procter & Gamble.
