Kristo Käärmann, the billionaire CEO of money transfer firm Wise, was slapped with a £350,000 ($454,000) fine by financial regulators in the U.K for failing to report an issue with his tax filings.
Käärmann, who co-founded Wise in 2011 with fellow entrepreneur Taavet Hinrikus, was on Monday ordered by the Financial Conduct Authority (FCA) to pay the sizable penalty due to a breach of the watchdog's senior manager conduct rule.
