Monzo Bank Limited, trading as Monzo , is a British online bank based in London, England. Monzo launched as part of a wave of app-based challenger banks entering the UK market. Originally operating through a mobile app and a prepaid debit card, in April 2017 its UK banking licence restrictions were lifted, enabling it to offer a full current account. As of June 2024, Monzo reported having 9.3 million registered users, though the number of active accounts is not specified. Their most recent financial results, issued in June 2024, showed an annual net profit of £15.3 million (a increase from the £116.3 million lost in the previous year) on revenue of £880.0 million.
