Rich Ricci, the ex-Barclays investment banking head who had been a close lieutenant of Bob Diamond and one of the bank's famed "four musketeers" before his 2013 exit, has joined the fintech revolution as the chairman of a currency exchange platform.

He has been named the chairman of London-based freemarketFX, according to a February 10 statement. The currency exchange was set up by Alex Hunn, who had worked in exchange-traded products at Credit Suisse, Deutsche Bank and MF Global and aims to cut out banks and brokerages in the FX market by offering currency exchange services.
