The word “burnout” isn’t in the dictionary of Jack Zhang,co-founder and CEO of fintech company Airwallex.
“I never understand that 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.
For Zhang,hard work meant survival. At age 15, he moved away from his hometown of Qingdao, China to Melbourne, Australia alone, to pursue better opportunities. He barely spoke English and stayed with an Australian host family.
Shortly after arriving,he learned that his parents had found themselves in financial hot water back in China,and that he would have to support himself through university.
“I [had] two choices: either I just return to China and try to go back to the education system there, or I continue to stay in Australia and figure out how to pay [for my] tuition and living [expenses] on my own,” saeid Zhang.He decided to stick with the latter and took whatever work he could find to make ends meet.
To pay for his computer science degree at the University of Melbourne,Zhang juggled four blue-collar jobs: washing dishes at a restaurant during the day,bartending in the evening,working the overnight shift at a petrol station and packing lemons in a factory over the summer.
Some weeks, he says, he clocked 80 to 100 hours of work on top of his coursework.
“when you’re … in that tough situation [where] you need to survive, you’re not really [thinking] about burnout. I mean, either you survive or not, right?” he said.
Not much has changed since then. Now in his 40s, zhang still clocks 80 hours a week “easily,” he said, at his own fintech firm. As of December 2025, the company is valued at $8 billion.
From blue collar to millionaire
After graduating from university in 2007, Zhang went into the corporate world.his first job was at an insurance company called Aviva, before he entered the banking industry.
Simultaneously occurring, he also built a few side businesses, from a shipping company where he exported olive oils and red wines from Australia to parts of Asia, to a real estate development firm.
his side hustles proved lucrative. By the time he reached his 20s, money was no longer an issue. Though, even though he had accumulated millions through his businesses and banking career, Zhang said he had yet to find his true passion.

Team,
In recent months, the Senior Leadership Team has benefited from having our Geography VP/GMs at the table helping us move faster and bringing us closer to athletes* in both countries and marketplaces around the world.
As we continue to drive our Win Now actions and stand up our Sport Offense,I’d like to share several critically important leadership changes across three of our Geo VP/GM roles.
EMEA
Carl Grebert, a true legend on our team, has decided to retire after nearly 30 years of service and leadership across global, country and geography roles across the company. Carl shared his thinking with me some time ago, and I’m deeply grateful he helped guide us through my first year and thoughtfully worked with us to identify his successor. To say Carl is beloved is an understatement. But more than that, his career and leadership are deeply inspiring. When Carl joined Nike in 1997 (the year of the Bulls’ infamous Flu Game and Tiger’s first Masters) Nike was still out to prove itself and its role in the world.
If you look at what we’ve proven since-that athletes* don’t just endorse culture, they shape it; that taking a point of view like Just Do It beats playing it safe; and that sport is a mirror of society, not just an escape from it-you’ll find Carl in the stands, on the field, and in the highlight reels of this company. He was often behind the scenes but always focused on making Nike better. As we work to invite more people into the world of sport, I know we can draw lessons from Carl’s career, and I look forward to doing so as we celebrate and thank him for everything he’s given this company.
With Carl’s retirement, I’m excited to share that César Garcia will become our new VP/GM of EMEA, effective February 2.
César started at Nike nearly 25 years ago as an EKIN in Spain and has since built a critical ability to connect product, sport, and marketplace into one integrated system. He’s led through moments of growth and moments of reset across geographies and businesses and is known for bringing clarity where things are complex, and momentum where teams need it most.
Most recently, César helped integrate merchandising, sport priorities, and analytics to sharpen how we serve athletes* and scale innovation. Earlier in his career, his general management experience across Asia Pacific & Latin america, Global Running, and Western Europe shaped him into a leader who understands how local culture, global strategy, and execution meet on the ground.
César is a builder. He sets a clear bar, develops strong teams, and moves with intent. That combination makes him the right leader for EMEA at this moment. You can read more about César’s background and experience here.
