Checkout.com

Checkout.com processes online payments for businesses. Guillaume Pousaz founded the company in 2012, and he still runs it. It is based in London.

The company lets merchants accept card payments and other methods, such as digital wallets and local payment schemes, through a single integration. It handles acquiring, processing, fraud detection and payouts. Merchants can see their payment data in one dashboard and adjust routing and fraud rules to raise approval rates.

Checkout.com focuses on large digital businesses rather than small shops. Its customers include online retailers, travel companies, marketplaces, gaming firms and fintech apps. It holds licences in several countries and operates offices across Europe, the Americas, the Middle East and Asia. The company has raised money from many large investors over the years. It has also cut its own internal valuation at times, which it has spoken about openly. Checkout.com remains privately held and has not announced plans to list its shares.
