Financial technology giant Revolut reported its first-ever annual profit in 2021, according to financial accounts released Wednesday, as subscriptions to its paid packages and overall usage of its app grew sharply.

The company reported revenues of £636.2 million ($767.1 million) for the year, three times what it made the previous year, and swung to a pre-tax profit of £59.1 million. In 2020, Revolut recorded a pre-tax loss of £205 million.

Revolut's announcement is a rare positive piece of news in a fintech market that has been plagued by mass layoffs and huge valuation cuts as investors reassess the space amid worsening macroeconomic conditions.

Klarna, the Swedish buy now, pay later fintech, saw its valuation plunge 85% to $6.7 billion last year. On Tuesday, the firm posted a record $1 billion loss in its 2022 fiscal year.

For 2022, Revolut gave a trading update saying it expects revenues to have grown more than 30% to £850 million, citing a diversified business model. As a privately held firm, it is not required to share frequent quarterly reports.

However, Revolut was late to producing its accounts to the U.K. company register, Companies House, in time for a Dec. 31 deadline. They were finally signed off by BDO, Revolut's auditors, last month.

Revolut reportedly faced concerns from U.K. regulators over the robustness of its internal financial controls. In September, BDO's audit of Revolut's 2021 accounts was deemed "inadequate" by the Financial Reporting Council, which said that "the risk of an undetected material misstatement was unacceptably high."

The company, which has no physical branches, offers digital banking, money transfers, and cryptocurrency and stock trading through a single app. It competes with the likes of Wise, Monzo and Starling.

Founded in 2015 by former Lehman Brothers trader Nikolay Storonsky and software developer Vlad Yatsenko, Revolut has quickly grown to become one of Europe's largest fintech unicorns, with a valuation of $33 billion.

Revolut has been pushing hard into overseas markets, in particular the U.S., where it currently has over 500,000 clients. The firm has also opened operations in Brazil, Mexico and India. In November, Revolut announced it has 25 million users worldwide.

Closer to home, though, the company's growth plans have been dealt some setbacks. Revolut has been pursuing a banking license in the U.K. for the past two years, in an effort to source more of its income from lending activity.

That process has been a drawn out one, and it is believed the wait is in connection with the delays to the publication of Revolut's results. Revolut has also faced criticisms over an aggressive working culture, which has reportedly led to departures of key regulatory and compliance executives.
