Runs global payments and accounts for businesses
Airwallex is the AI-native financial operating system for a real-time, intelligent economy. More than 675,000 businesses, including McLaren Racing, Qantas, SHEIN, and TikTok, use us, directly or through our platform partners, to run their financial operations or build and monetize financial products of their own.
We started in Melbourne in 2015 to build the infrastructure global commerce runs on. We're the regulated backbone behind global payments: not by accident, but by design. A decade plus, 85+ licenses, and a financial infrastructure spanning North America, Europe, the Middle East, and Asia-Pacific.
We're co-headquartered in San Francisco and Singapore, with more than 2,700 people across 27 offices. We hire builders with founder-level energy, people who move fast with good judgment, dig in with real curiosity, and make calls from first principles rather than waiting to be told what to do. Read our operating principles to see it in full.

InfoSec at Airwallex runs one of the most modern security teams in the world, protecting hundreds of thousands of customers and hundreds of billions of dollars. Our scale, funding, and industry make us a real target, so we skip the standard playbook of off-the-shelf tools and tiered SOC analysts and build almost everything ourselves, often with AI ahead of the rest of the industry. You'll go back to first principles constantly, because the off-the-shelf answer is rarely right for us, and we can build better than what already exists. If you want to build security from the ground up, against a real adversary, with people who are actually good at this, this is the team for you.

Airwallex runs a financial platform for businesses that sell, buy and operate across borders, from startups to large enterprises. Its multi-currency accounts let customers receive and hold money locally, then pay overseas suppliers without converting every sale into their home currency. Businesses also use its corporate cards and expense controls to manage spending, while online sellers accept customer payments through its checkout tools. Finance teams work in a web app, and developers embed the services in other software; Airwallex earns transaction fees and charges for paid software plans. Founded in Melbourne in 2015, Airwallex has dual headquarters in Singapore and San Francisco.
