Mobile banking for personal and business
Starling Bank is a digital bank in the UK offering personal and business current accounts through a mobile app. For individuals, it provides features like instant spending notifications, insights, and Spaces (pots) to separate money. For businesses, it offers business accounts with invoicing and accounting integrations. The app handles account management, payments, and budgeting in one place, with transactions processed online and via card payments. The bank earns revenue from card interchange fees, interest on balances held with the central bank, and lending (such as personal loans and overdrafts). 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.
