“Can a UK neobank that is also a chartered bank turn its proprietary technology stack into both the best SME banking product and a B2B BaaS platform that powers other regulated fintechs?”
Founded as a UK challenger bank with a mobile-first personal current account, Starling rapidly expanded into SME banking and built a proprietary app marketplace for third-party financial services. A pivotal evolution was the launch of Starling Banking Services (SBS), transforming its in-house technology stack into a B2B BaaS proposition offered to other regulated fintechs and financial institutions across the UK. This positioned Starling not just as a consumer/SMB bank but as embedded finance infrastructure — effectively becoming both a licensed bank and a platform business.
