Tandem bank, which has around 600,000 customers, said it was in the early stages of talks to secure an investment in the next three months, which was likely to be larger than the £80m raised when it took over Harrods Bank last year.
Last September Tandem struck a deal with Hong Kong-based Convoy to use its technology to work on a new digital lender in the city, but Tandem is now looking to directly expand into several countries, starting with trials in continental Europe by the end of this year. That follows similar moves by several of its digital rivals. Starling Bank is planning to start operating in Ireland this year, while Monzo is plotting a push into the United States. Revolut, which initially focused on travel money before expanding into broader banking services, has been particularly focused on international expansion, with plans to move into more countries including the US, Australia, Canada and Japan.
