Airwallex Founder Rejected $1.2 Billion Stripe Acquisition, Forging a Path of Maximum Resistance

Jack Zhang, at 34 years old and just three and a half years into building his fintech startup Airwallex, found himself in a remarkable position: seated in the opulent Silicon Valley home of Michael Moritz, a titan of venture capital at Sequoia Capital. The invitation was not for a routine pitch, but a compelling case for acquisition. Stripe, the dominant force in online payment processing, had made a bold offer: $1.2 billion for Airwallex. This was at a time when Airwallex was generating approximately $2 million in annualized revenue, presenting a staggering revenue multiple of around 600 times. Moritz, arguing that Stripe’s founder Patrick Collison was a generational entrepreneur, posited that the acquisition would "compound" into something extraordinary.

Zhang, despite the allure of such an astronomical valuation for a nascent company, was thrown into a period of intense introspection. He spent two weeks walking the streets of San Francisco, his mind a whirlwind of indecision. Ultimately, he accepted the offer. However, the moment he stepped onto the plane for the nearly 8,000-mile journey back to his base in Melbourne, a profound shift occurred. The initial "yes" began to unravel.

"I really went deep on what motivates me to build Airwallex," Zhang shared in a recent conversation. "I was three and a half years into the business. The business was growing 100 times in 2018. And I only just sort of tasted what it [was like] to be an entrepreneur. And that’s what I’d been dreaming about." This nascent entrepreneurial fire, ignited by the challenges he had overcome, proved more potent than the immediate financial windfall.

The internal dynamics of Airwallex also played a role. Two of his three co-founders had initially voted against the deal, a sentiment that resonated with Zhang’s own evolving perspective. However, the most decisive factor came from within his own company. Looking at the whiteboard in his office, the unfinished vision of Airwallex—to construct the financial infrastructure enabling any business to operate globally as if it were a local entity—remained a powerful, unfulfilled promise. This clarity solidified his resolve.

Zhang’s decision to decline the acquisition, which now appears remarkably prescient, has positioned Airwallex for significant growth. The company now boasts over $1.3 billion in annualized revenue and continues to expand at an impressive 85% year-over-year. It processes nearly $300 billion in annualized transaction volume. Zhang readily acknowledges that this trajectory has been far from easy, asserting that the very difficulty is intrinsic to its value.

The Foundations of Resilience: A Journey Forged in Adversity

Zhang’s deep-seated conviction and his approach to building Airwallex are inextricably linked to his personal journey. He grew up in Qingdao, a bustling port city in northeastern China. At the age of 15, he relocated to Melbourne, Australia, without his parents. Arriving with limited English proficiency and living with a host family, he faced immense challenges. The collapse of his family’s finances necessitated a relentless work ethic to fund his computer science degree at the University of Melbourne. As detailed in the Australian Financial Review, his resume included bartending, dishwashing, graveyard shifts at a gas station, and the grueling work of picking lemons on a farm during school holidays – a job he still describes as the most challenging he has ever undertaken. He later spent years in the front office of an Australian investment bank, writing trading code. While this role offered financial security, it lacked the profound sense of fulfillment he craved.

This early exposure to hardship and the pursuit of purpose laid the groundwork for his entrepreneurial endeavors. Before Airwallex, Zhang had already launched approximately ten businesses. These ranged from a magazine at age 14 to a real estate development company, import-export ventures dealing in Australian wine and olive oil, textiles, and even a burger chain.

The Genesis of Airwallex: A Pain Point in Global Commerce

The idea for Airwallex took shape while Zhang was operating a Melbourne coffee shop. His co-founder, Max Li, encountered significant friction when attempting to pay coffee bean suppliers in Brazil, Indonesia, and Guatemala. Payments were frequently lost or delayed within the correspondent banking system, flagged and frozen by intermediary U.S. banks enforcing OFAC sanctions. This recurring problem spurred Zhang to delve into the intricacies of correspondent banking and the SWIFT system, ultimately leading to the ambitious goal of building Airwallex’s own global money movement network.

The "Path of Maximum Resistance": Building Enduring Infrastructure

The core vision for Airwallex remains the same, but its execution has been dramatically scaled. The company has strategically pursued and obtained nearly 90 financial licenses across 50 markets, a number Zhang estimates to be roughly double that of Stripe. This licensing effort has been a monumental undertaking, with the process in Japan alone spanning seven years. In certain emerging markets, Airwallex has acquired dormant shell companies that held licenses no longer being issued by central banks, and then rebuilt the underlying technology to meet modern standards.

"You can’t really vibe-code an integration with Mexico’s central bank," Zhang explained, highlighting the tangible, secure environments required. "We have to have a secure room – you have to do a biometric scan just to walk in to access the central bank integration."

The strategic advantage of holding these licenses extends beyond regulatory compliance. In Japan, for instance, while competitors like Stripe and Square can process payments, they are mandated to transfer funds immediately to a merchant’s bank account. Airwallex, with its fund transfer operator license, can retain these funds within its ecosystem. This capability allows clients to issue bank accounts and cards, and spend money without it ever leaving the Airwallex platform.

The foreign exchange economics alone are substantial. A U.S. merchant settling transactions in Australian dollars can bypass the typical 2% to 3% conversion fees charged by processors like Stripe. They can then utilize these local balances to pay local vendors, manage payroll, and cover digital marketing expenses, all at interbank rates. "You don’t really operate like a U.S. company anymore," Zhang noted. "You operate like a company with entities around the world, but without needing to physically set up those entities."

This deliberate, slow build is encapsulated in Zhang’s framework: the "path of maximum resistance." Each license, each bank integration, and each local payment rail meticulously assembled by Airwallex creates a formidable barrier to entry for competitors. "It took us six and a half years to get to $100 million in annual recurring revenue," Zhang stated. "But after that, it took just over three years to get to a billion."

The competitive logic, in Zhang’s view, boils down to a fundamental distinction between owning infrastructure and merely operating on top of someone else’s. Without control over the end-to-end payment workflow, addressing issues and developing new products becomes significantly constrained. "Building on top of other infrastructure," he concluded, "is simply not scalable."

The Widening Competitive Arena

Historically, Airwallex and Stripe have operated in largely distinct geographic markets and served different customer segments. This is evolving. As Stripe expands its international reach and Airwallex makes its initial significant inroads into the United States, their competitive overlap is increasing.

Airwallex’s traditional customer base has been CFO offices in Australia and Southeast Asia—finance directors and treasury teams. This contrasts with Stripe’s model, which has largely been adopted by U.S. developers as a default starting point for new companies. Currently, over 90% of Airwallex customers begin with a business account product, with payments and spend management following. Zhang reports that more than half of their customers utilize multiple products.

Navigating Brand Perception and Market Valuation

Zhang does not shy away from the challenges ahead. A primary hurdle is Stripe’s status as Silicon Valley’s darling, with its privately held shares having created significant wealth across the tech industry. The accompanying brand recognition gap is another significant factor. Airwallex needs to embed itself not only in the minds of finance teams but also among engineers and developers, becoming an instinctive choice for founders. "Our brand is just not there yet," Zhang admitted. "That’s a harder competition to win."

This burgeoning competition is being closely observed by various stakeholders. Sequoia, through its Sequoia Capital China arm (now rebranded as Hongshan), was an early investor in Airwallex and remains a significant shareholder. Greenoaks Capital also holds stakes in both companies, a situation Zhang dismisses as a natural consequence of investors betting on a large and expanding market.

The disparity in valuations is also a focal point. Stripe was valued at $159 billion in a February tender offer, a 74% increase from the previous year, following $1.9 trillion in total payment volume processed in 2025. Airwallex, with an $8 billion valuation following a Series G funding round in December, is valued at approximately one-twentieth of Stripe. However, Zhang points out that Stripe’s payment volume is only about six times that of Airwallex, not twenty times. With 85% annual growth and projections of $2 billion in revenue within the next year, Airwallex is narrowing the revenue gap at a pace that outstrips the valuation disparity.

The question of whether the market will ultimately recognize this convergence remains open, a question that an initial public offering (IPO), which Zhang anticipates is at least three to five years away, will likely force into the public discourse.

Future Horizons: AI-Powered Finance and Sustainable Growth

Zhang’s immediate focus remains on long-term objectives: achieving one million customers by 2030, generating $20 billion in annual revenue, and increasing average revenue per customer from approximately $12,000-$13,000 to around $20,000. The company is currently rolling out a suite of AI-powered autonomous finance products, featuring agents capable of not just surfacing data but actively executing transactions. The underlying thesis is that a decade of accumulated financial data across the entire corporate finance stack—from revenue collection to treasury management, vendor payments, and expenses—has created a unique training set that competitors cannot easily replicate.

The critical question now is whether Airwallex’s relentless pursuit of infrastructure ownership and its deep technological moat will be sufficient to chip away at Stripe’s dominant market share. For the moment, the rivalry appears to be playing out from a strategic distance. While Zhang and Patrick Collison were never close friends, they maintained a cordial relationship during the past merger talks. Last year, both founders were present at Greenoaks Capital’s annual gathering, but they did not engage in conversation. The narrative of Airwallex’s deliberate ascent, forged in the crucible of adversity and driven by a vision of end-to-end financial infrastructure, continues to unfold against the backdrop of a rapidly evolving global fintech landscape.
