D1 Capital Partners has paid $200 million for a four percent stake in TransferWise, raising the company's valuation to $5 billion.
Sky News has learnt that the US hedge fund, which has shares in Amazon, Facebook and Netflix, bought the TransferWise stake as part of a secondary share sale that was signed last week.
And while other big-name fintechs are raising cash at a discount to previous valuations, the TransferWise transaction was signed at a 30% premium to an almost identical share sale just over a year ago.
The deal sees TransferWise's valuation soar by $1.5 billion since last year's sale, which raised $292 million.
The fintech Unicorn now employs 2,200 people, boasting eight million customers and £4bn in monthly cross-border transaction volumes.
