A capital markets specialist at Funding Circle has left the London-based peer-to-peer lender to join Deutsche Bank, in an unconventional switch back from fintech to banking,

Karl Gilbert, who joined Funding Circle as a vice president in its capital markets division in October 2014, left the P2P lender in November to move to the German bank as a vice president in its global equities team, according to the UK's Financial Services Register and a person familiar with the move.
