Global financial platform Revolut has secured its place as the U.K.’s most valuable fintech. The London-based company secured a $500 million investment, bringing its total funding to $836 million.

With this, Revolut’s valuation tripled, escalating to $5.5 billion. As a comparison, digital bank Monzo was valued at $2.6 billion last year. Revolut’s funding was led by U.S. investor Technology Crossover Ventures while a handful of undisclosed existing investors also contributed.

The funding will be used to enhance Revolut’s customer experience, grow its workforce, and create new products that entice users to log into their accounts more frequently. As a part of this, Revolut will use the funds to enhance Premium and Metal subscription account offerings. These paid products are not only a significant part of Revolut’s business model, they also show huge promise, growing by 154% last year alone.

“We’re on a mission to build a global financial platform – a single app where our customers can manage all of their daily finances, and this investment demonstrates investor confidence in our business model,” said Revolut CEO and founder Nik Storonsky. “Going forward, our focus is on rolling-out banking operations in Europe, increasing the number of people who use Revolut as their daily account, and striving towards profitability.”

Revolut employs 2,000 people across 23 global offices. The company counts more than 10 million customers and has processed one billion transactions worth $130 billion since it was founded in 2013.

The company has seen significant success since its early days. Just last year Revolut increased customer growth by 169%, boosted the number of daily active customers by 380%, and saw year-over-year financial revenues grow by 354%. The company aims to continue this growth by launching lending services for retail and business customers, extending high interest savings accounts beyond the U.K., improving customer service, and rolling out banking operations across Europe.
