Airwallex is a financial technology company founded in Melbourne in 2015 that builds cross-border payment and treasury infrastructure for businesses. It holds payment and money transfer licences in a large number of jurisdictions, which lets customers open local currency accounts, collect and pay out in dozens of currencies, issue cards and embed those capabilities through APIs rather than assembling bank relationships themselves. The company moved its headquarters to Singapore, serves marketplaces, software platforms and international ecommerce sellers, and has raised more than a billion dollars from growth investors.
