South Korean retail conglomerate Lotte is bringing London mobile shopping tech start-up Rezolve into its market. The Korean firm will incorporate the start-up’s IT product, which allows customers to take advantage of deals in print by scanning them with their mobile devices in Lotte’s supermarket app. Lotte earns a large proportion of its supermarket revenues – last year valued at KRW17.8bn (US$15.3mn) – via its printed promotional brochures. The deal is Rezolve’s largest yet, compared with the firm’s existing operations in China, India and Taiwan.
