Our story
OakNorth Bank was built on the foundations of frustrations with old-school 2005 when our founders tried to get capital for their data analytics company the computer said no. Unfortunately all major banks in the UK were using the same computer and it was broken.
Why was it so difficult for a profitable business with impressive cashflow retained clients and clear commercial success to get a loan
The industry was backward-looking and too focused on historic financials rather than future potential.
So what if there was a bank founded by entrepreneurs for entrepreneurs One that offered a dramatically better borrowing experience for businesses
No more what ifs OakNorth Bank exists.
