Kantox is a UK-based "FinTech" company that offers foreign currency exchange and international payment solutions for corporate clients.

Kantox was founded in 2011 by Philippe Gelis and Antonio Rami, ex-consultants in Deloitte, who realised the business need for an alternative high-tech solution for their foreign exchange operations.

The name of the company takes inspiration from the surname of Georg Cantor, the creator of the theory of transfinite numbers, a fundamental theory in the transformation of mathematical study in the late nineteenth century. Operating in the FX market, where daily turnover has been estimated by the Bank for International Settlements at $5.3 trillion, Kantox’s founders wanted a company name that reflected the almost infinite-like nature of the market. This led them to use Georg Cantor’s surname, adding an X to represent FX.

In 2014, Kantox raised €6.4 million in investment and one year later, announced reaching $1 billion in total corporate foreign exchange transactions. Eight months later, the company reached $2 billion in currency exchange transactions, from more than 2,000 clients.
