Salary benchmarks
Our take
The payments industry has exploded in the last decade as eCommerce continues to grow as the use of cash falls. Checkout.com is building the go-to platform for all things related to payments, such as accepting transactions, processing them and detecting fraud. Its secured a steady stream of funding from top investors like Tiger Global Management, and is the strategic payments partner for some of the best known fast-moving brands globally such as Patreon, Dashlane, Udacity, Wise, Sony Electronics, and Klarna.
It focuses on large merchants and try to make its product as customisable as possible, so that companies integrate Checkout.com as an infrastructure partner in their product. This increases the stickiness of the product and creates many opportunities for the company to generate revenue.
Checkout.com has high quality proprietary technology (its platform has been designed from the outset so it can easily deliver incremental services as it expands its offering) and claim to offer the most comprehensive cross-border payment solution for digital commerce.
