Currency Cloud is another start-up in the payments space.
The British firm provides cross-border money transfers for businesses. It sets itself up as a rival to banks that usually carry out this transaction, but says it is cheaper and faster than traditional players.
Founded in 2012, Currency Cloud now processes $15 billion a year and has over 125 customers.
The start-up raised $18 million last year from Sapphire Ventures and Japanese e-commerce giant Rakuten.
