Its approach combines mobile-first banking with a broad set of services in a single app, differentiating itself through the Spaces budgeting tool, real-time transaction insights, and a strong focus on both personal and business banking. Starling’s goal is to grow its customer base while expanding its lending portfolio and offering a complete digital banking experience in the UK.
