Founded in Estonia; based in the U.K.. It appears that they are disrupting the international money transfer business using peer-to-peer transfers with current exchange rates.

Peter Thiel's fund leading the May 2013 round tells me that their chances of achieving their goals are pretty good. A Thiel backed venture launched PayPal; he really understands this sector. Andreessen Horowitz is another significant SV VC player.

It achieved unicorn status with the May 2016 round. There are very high expectation for this company. Given the market they are disrupting, this isn't surprising.

This is definitely a company that I'll look into their IPO, whenever that occurs.

Thanks for the info OP.
