Bank challengers in Europe keep growing very fast. Only the eight major players*, including Revolut, N26, TransferWise, Monzo, Monese, Starling, Curve, and Tandem served nearly 27 million customers as of the end of 2019. In fact, their number of clients has increased exponentially as the figure doubled every year since 2016. Considering current trends, it can be expected that the selected group of bank challengers will get over 50 million clients by 2021. And, this is only a part of the broader market since there are dozens of other players across Europe already operating or planning a launch.
