From Lemon Factory to Fintech Unicorn: The Relentless Rise of Airwallex’s Jack Zhang

Table of Contents

Jack Zhang’s journey from working 16-hour shifts in Melbourne’s petrol stations to co-founding a multi-billion dollar fintech giant is no rags-to-riches cliché—it’s a case study in resilience, reinvention, and relentless pursuit of engineering-led impact. His personal story and the creation of Airwallex are inseparable. Here's how it unfolded.

Key Takeaways

  • Zhang’s earliest work experiences included 12-hour days in lemon factories and overnight petrol station shifts—at age 16.
  • Before Airwallex, he ran multiple side businesses: real estate, architecture, importing olive oil, reselling phone cases, and more.
  • The Airwallex founding idea came from cross-border payment inefficiencies exposed during a failed coffee shop experiment.
  • Initial VC rejections and a pulled term sheet nearly killed the company—before a chance meeting with a first-time angel saved it.
  • Zhang turned down Stripe’s $1.2B acquisition offer to pursue a bigger mission: to build the global financial infrastructure of the internet.

Humble Beginnings: Survival Mode in Australia

Jack Zhang’s entrepreneurial roots were forged not in tech accelerators, but in survival. At 16, stranded without financial support in Australia, he worked:

  • In restaurants as a dishwasher.
  • As a lemon box carrier—12 hours a day, 40°C heat, no lunch breaks.
  • Bartending at the Westin Hotel till midnight.
  • And immediately afterward, from 12 a.m. to 8 a.m., manning a petrol station.

He wasn’t optimizing for career development—he was trying to afford tuition as an international student.

"I worked 100 hours a week at age 16 because I didn’t have a choice."

From Side Hustles to First Fortunes

Even while working full-time, Zhang couldn’t stop building.

  • He founded over ten small businesses—none of which he loved, but most of which were profitable.
  • His ventures included importing wine, exporting textiles, real estate development, and selling mobile phone cases.
  • By his late 20s, he had made over $10 million and owned companies with 40-50 unit apartment projects.
  • His real estate partner? Future Airwallex co-founder Max Lee.

But something was missing. As Zhang put it: “Making money doesn’t make you happy. Building something meaningful does.”

The Accidental Insight: Coffee Shops, Payment Friction, and OFAC Blacklists

Zhang didn’t plan to start a fintech. He was opening a coffee shop.

  • While importing beans from Brazil and packaging from China, co-founder Max Lee’s payment was blocked due to an OFAC blacklist match.
  • Zhang dug into why global payments were so broken—and discovered the SWIFT system’s arcane structure.
  • “It’s 140 characters to send a multi-million dollar transaction.”

That pain point became the Airwallex origin story: a faster, more reliable, developer-friendly way to move money globally.

A Million-Dollar Stranger: The Angel Who Bet on a Conversation

The earliest capital didn’t come from a VC. It came from Lucy, a former investment banker Zhang met at dinner.

  • She was interested in the coffee shop.
  • After one conversation, she offered $2 million for 40% of his next startup.
  • They negotiated it down to $1 million for 20%.
  • She wired the funds before the company even had a name or registration.

That $1M investment turned into a potential billion-dollar stake.

Rejection, Pivot, Repeat: The Pain of Early Traction

Even with funding in hand, success was far from linear:

  • Matrix Partners pulled their signed term sheet after a call with their founder.
  • Local Australian VCs rejected him repeatedly. Ironically, they later joined at a $6.2B valuation.
  • Airwallex's first product idea—a P2P algorithmic remittance tool—flopped due to lack of volume.
  • Its next iteration—SMB invoicing—failed to find product-market fit.

Zhang persisted. He pitched the vision—not the traction—to Tencent and Sequoia China.

The Near-Death Save: Square Peg and the FX Infrastructure Pivot

With little runway and no revenue, Zhang bet on a technical pivot:

  • Cold-called Macquarie Bank at 8 a.m. on a hunch.
  • Convinced a junior FX trader to back the company with internal engineering support.
  • Built a real-time FX engine to plug into interbank liquidity—with $20 trade capability.
  • Raised $6M from Square Peg, led by one of Zhang’s entrepreneurial heroes.

"This was the third product. First two failed. This one had to work."

Product-Market Fit (At Last): From Tuition Payments to Shein

The breakthrough came in 2018:

  • Airwallex onboarded an edtech firm and Shein for tuition and supplier payouts.
  • With just two major clients, the company processed $1B in transaction volume in nine months.
  • They had only 100 customers—but the right ones.
  • Soon after, Sequoia, Tencent, and Mastercard co-led an $80M round at $480M post-money.

This momentum proved the vision—Airwallex wasn’t a payments tool. It was the foundation layer for global money movement.

The Stripe Buyout That Almost Happened

In late 2018, Stripe expressed interest in acquiring Airwallex.

  • Patrick Collison flew to Shanghai to meet Zhang.
  • They shared a daylong vision session, mapped out financial infrastructure ambitions.
  • Stripe proposed a $1.2B deal—$800M on cap table, $350M for founders, $50M in employee retention.
  • Zhang nearly accepted.

But after returning to Melbourne, he put the question to his team—and 90% voted to keep building.

Building for Decades: Why Zhang Said No to $3B

Zhang’s decision wasn’t about money—it was about mission.

  • “I grew up in Australia. I don’t live a luxury life. I didn’t need the money.”
  • Inspired by Collison’s 30-year commitment to Stripe, Zhang decided to make Airwallex his life’s work.
  • In his words: “I want to build the AWS of global finance.”

The Aftermath: Raising Hundreds, Scaling Billions

Airwallex’s growth accelerated:

  • Raised $100M from DST Global at a $1.1B valuation.
  • Expanded global licensing, FX infrastructure, and API capabilities.
  • Quietly became one of Asia-Pacific’s only truly cross-border financial networks.

And yes, the early detractors—from Australian VCs to Matrix—eventually returned to invest.


Jack Zhang’s rise isn’t a fluke. It’s an ode to stamina. From washing dishes to rewriting how money moves, his playbook is simple: build the thing no one else dares, never stop coding, and choose meaning over exit.
