Interview: The tech stack helping ‘q-commerce’ scale at Tesco
Tesco's rapid delivery service, Whoosh, has grown by 51% to £400m in annual sales, serving 74% of the UK population. The service is integrated into Tesco's existing digital and store platforms, avoiding separate technology stacks. Tesco developed most of the technology in-house, with third-party tools used selectively. The model allows for scalability and innovation within the broader retail ecosystem.
