Our take

The cost-of-living crisis has put pressure on small and medium-sized businesses, making it harder for them to access the financing they need to thrive. And traditional banks often overlook these businesses, leaving a gap in the market for tailored financial solutions.

OakNorth is filling this gap, with its digital bank that provides loans to lower mid-market businesses. By leveraging advanced technology and data analytics, it offers better lending solutions compared to traditional banks.

Its impact is growing too. As of early 2025, it surpassed $1B in lending to US businesses since launching operations there in mid-2023. This is a huge milestone and one that reflects the demand for its services. With this success, the company is in a great position to continue expanding and helping even more businesses achieve their growth objectives.
