Fintech firm Revolut raised $250 million bringing its valuation to $1.7 billion, the company said Thursday.

The London-based firm provides a debit card that allows people to spend money in 150 currencies with no fees at a real-time exchange rate. It has since expanded services to offer a current account, cryptocurrency trading and insurance.

DST Global, a company that was early investors in Facebook and Spotify, led the funding round, which included other high profile venture capital firms Index Ventures and Ribbit Capital.

Revolut has now raised $340 million since it launched in 2015.

The company said that it has 250,000 daily active users, with the aim of getting 100 million on board in the next five years.

Revolut faces stiff competition, however, from a number of fast-growing fintech companies including TransferWise and Monzo. TransferWise, also a U.K. start-up, reported its first profitable year in fiscal 2017. Its CFO Matt Briers told CNBC in a recent interview that it will book another year of profit in fiscal 2018. The company also launched an account and debit card aiming to take on Revolut.

Monzo is an app-only bank and offers many similar features to Revolut. Chief Executive Tom Blomfield recently told CNBC that the company is in the early stages of talks to expand to the U.S. Revolut recently launched a trial in America.
