Airwallex CEO Jack Zhang has said that he still works 80 hours/week "easily" at his fintech startup. "I never understand the (burnout) terminology to be honest. I've worked 100 hours a week from [the] age of 16 for 20 plus years," Zhang told CNBC Make It. Airwallex was valued at $8 billion during Series G funding round in December 2025.
