About Us

CurrencyFair was originally established in 2009 by a team who had the vision to create the world’s first peer-to-peer foreign exchange marketplace that enables consumers and businesses to save substantial sums of money when transferring money abroad. We believe that all customers should come first, by having access to a simple, transparent and innovative product which eliminates hidden fees and uncompetitive exchange rates offered by Banks. We have our headquarters in Dublin and offices in Australia, Hong Kong and Singapore and we are now planning an expansion into the Asian market. With our growth plans, we are looking to add to the amazing team we already have here at CurrencyFair.
