Interim Chief Executive Officer

Having joined dunnhumby in April 2021 Claire’s role is to help steer dunnhumby during its next phase of growth, and support the business as interim Chief Executive Officer in continuing to deliver Customer First products and services globally.

Before joining dunnhumby, Claire was most recently Group Innovation Director at Tesco, where she led a team responsible for finding disruptive innovation, working with start-ups to jointly nurture and develop ideas. Prior to this, Claire was Chief Executive Officer of Tesco Mobile, the UK’s largest mobile virtual network operator and the 5th largest mobile network in the UK.
