The majority of Pousaz's fortune is derived from his major shareholding in Checkout. The London-based company provides payment processing in more than 150 currencies and has more than 1,700 employees across about 19 offices worldwide, according to its website.

Pousaz's the majority shareholder of the Jersey-based holding company that controls Checkout, according to UK business registry filings, and he's credited with a 51% stake in this analysis. Checkout received a $40 billion valuation from a January 2022 fundraising round, according to a company statement. It raised money at a $15 billion valuation in 2021. The valuation was updated on Jan. 14, 2022, for Checkout's latest fundraising, leading to a rise of about $12 billion.

Lewis Jones, a spokesman for Checkout, confirmed in July 2021 that Pousaz is the company's largest shareholder but declined to provide a precise figure for his stake.

Born in Geneva during August 1981, Pousaz grew up in Switzerland and went to university in Lausanne before he quit his studies and moved to California following the death of his father from pancreatic cancer.

He worked in the US for a payments firm and left the business to launch in 2012 by acquiring another business in the industry in Mauritius. The London-based company held a series A fundraising in 2019 and held another the following year to take its valuation to $5.5 billion.

Checkout received a $15 billion valuation through a 2021 fundraising round led by Tiger Global Management, according to a company statement, making it Europe’s biggest start-up at the time.

Pousaz, a father of three, lives in the United Arab Emirates.
