Dunnhumby has appointed Jamie Samaha as Chief Executive Officer. He is set to lead the specialist in customer data-driven retail optimisation from 20 July 2026. Jamie Samaha is tasked with further expanding Dunnhumby’s market position in both in retail and the branded goods manufacturers industry.
Jamie Samaha joins from Reward, where he most recently served as CEO. Prior to that, he worked at fintech firm Prezzee and Mastercard, amongst others. Dunnhumby, which was originally developed as the exclusive supplier to UK’s leading retailer Tesco, highlights his experience in the fields of commerce media, loyalty, payments and customer engagement.
Jamie Samaha succeeds Josh Bottomley, who is stepping down after three years at the helm of the company. Josh Bottomley is set to remain with the company until mid-July to oversee the handover. No reasons have been given for his departure from Dunnhumby.
Grew up with Tesco’s Clubcard
Dunnhumby is one of the leading specialists in customer data science. The company helps retailers and branded goods manufacturers translate customer data into actionable insights, for instance in pricing, promotions, e-commerce, media and product range decisions.
For the retail sector, Dunnhumby plays a key role particularly where retailers wish to systematically use customer data to drive growth, customer loyalty and more precise marketing. From 1994 onwards, Dunnhumby had developed the analysis of data collected via the Clubcard for Tesco. Later, the company expanded its offering to include solutions for advertising effectiveness measurement, category management and retail media, amongst other things.
Its client base extends far beyond Tesco
In addition to Tesco, Dunnhumby’s current clients include Meijer, Walmart Data Ventures, Ahold Delhaize, Carrefour via Majid Al Futtaim, Metro, Coop Norge, RD Saúde and Grupo Éxito. On the brand manufacturer side, the company works with Unilever, Nestlé, Coca-Cola, Danone, Mondelez, L’Oréal and McDonald’s, amongst others.
With the acquisition of pricing and promotion specialist KSS Retail in 2010, Dunnhumby began to open up its traditionally exclusive business model. Historically, Dunnhumby worked in many markets for just one retail company at a time — for example, with Tesco in the UK or Kroger in the US — and was long regarded as a strategic data and loyalty partner to individual retail groups.
Open for all retailers
However, through the integration of KSS Retail and the subsequent restructuring of its joint venture models, Dunnhumby expanded its offering to all retail companies. The aim was to provide a comprehensive range of strategy, analytics, pricing and promotional solutions from a single source.
