In January 2022, Checkout.com raised $1 billion from private investors, valuing the company at $40 billion. In December 2022, Checkout.com marked down its internal valuation to $11 billion, as fintech valuations tumbled during the year; a year later it was lowered to $9.35 billion. In 2025, it rose to $12 billion, according to the company. Pousaz, who is CEO of Checkout.com, owns an estimated nearly two-thirds of the London-based company.
