$11B Airwallex Founder Jack Zhang's Crazy Journey: Choosing Happiness Over Valuation, Turning 1M into 500M, and Saying No to >$3B of Stripe Stock

Airwallex founder rejected $1.2bn to build a global bank

Jack Zhang has repeatedly picked long-term ambition over a quick exit, including a $1.2bn offer when Airwallex had about $2m in revenue. He argues that a global finance platform only works at scale, and that AI agents will make it the operating system for company finance. Airwallex now sits near $1.5bn in ARR.

Takeaways

• He refused $1.2bn to build a bank. The Collinson brothers offered $1.2bn when trailing revenue was about $2m. A five-year lockup would have run to age 39, and Zhang wanted to build a new global bank instead. Transaction volume grew 100 times that year.
• Scale is the whole game in fintech. Airwallex took six years to reach $100m ARR and three more to reach a billion. It now has about $1.5bn, grew 76 percent last quarter, and expects nearly $2bn by year end. Zhang calls fintech high-risk and low-margin.
• Agentic banking replaces the CFO's software stack. Zhang sees a horizontal operating system replacing a dozen vertical software categories in the CFO office. Banks lack APIs, so he expects fintech hyperscalers like Airwallex and Stripe to own the next decade. MessageBird cut finance staff from over forty to under ten.
• Stablecoins will spread slowly, not overnight. Cash took 30 to 50 years to fade, and Zhang expects stablecoins to follow a similar gradual path. Round-the-clock settlement makes sense, but money will still move across many rails. In one $1m FX trade, $400,000 settles on stablecoin while $600,000 lacks liquidity.
• Airwallex says its China operations are walled off. Rival Silicon Valley investors accuse Airwallex of passing US data to the Chinese Communist Party. Zhang says the China and Hong Kong operation is almost a separate company with its own data security, and US data stays in a US data centre.
• Hardship and side businesses led to Airwallex. Zhang left China for Australia at 15 and lost parental support at 16, then washed dishes, tended bar and packed lemons 12 hours a day. After about ten side businesses, he wanted something scalable that used his engineering skills.

How the first million arrived

1. Lucy, a friend of cofounder Max who had just left her banking job, met Zhang at the coffee shop.
2. Over dinner Zhang said they were probably raising a million dollars, and Lucy offered two million on the spot.
3. Her husband objected the next morning, and by 11:30 a.m. terms were agreed at $1m for 20 percent, a $5m valuation.
4. By Monday midday the million was wired to Zhang's personal account, before anything was signed.
5. Tommy Stadlen says Lucy turned that million into about half a billion dollars, though she has sold part of her stake.
