Carbs and caffeine is a formula that has fuelled Coco di Mama’s expansion well. The fast-casual brand has been deftly serving long queues of office workers just that since 2011. This sweet spot customer, the 25-35-year-old affluent City worker, was the genesis of the brand in Fleet Street. While this core demographic served Coco well in its early years, a new management team last year realised it needed to broaden its appeal if it was to continue its expansion into adulthood.
