“This hasn’t been a good week for challenger bank Revolut . The company, which offers digital banking services and is valued at $1.7 billion, confirmed today that embattled CFO Peter O’Higgins has resigned and left the business. The startup and O’Higgins have been under pressure after a Daily Telegraph report revealed that Revolut switched off an anti-money laundering system that flags suspect transactions because it was prone to throwing out false positives.”
