25-year-old finance graduate met a techie over casual dinner and invested $1 million in his fintech idea. What it became will leave you stunned

A chance dinner conversation in Melbourne has gone down as one of the most extraordinary angel investment stories in global startup history. What began as a friendly meal between a young finance graduate and two aspiring entrepreneurs became the seed of a fintech empire now worth billions.

A dinner that changed everything

Jack Zhang, Founder and CEO of Airwallex, recounted the story during a conversation on the podcast 20VC with Harry Stebbings. He described how he met Lucy Liu, then a 25 year old finance graduate, through a mutual friend while discussing plans to build a company that could radically transform cross border payments.

According to the podcast, Lucy had just left her investment banking job and was curious about Zhang’s business ideas. What started as a casual discussion about a coffee venture quickly turned toward a bigger vision, a platform designed to revolutionise how money moves across borders by simplifying international transactions.

The bold investment offer that sealed the deal

As Zhang shared on 20VC, when he mentioned he was planning to raise one million dollars to launch the business, Liu stunned him by offering two million dollars on the spot. The pair spent hours the next day negotiating. They eventually agreed that she would invest one million dollars for a 20 percent stake. Zhang revealed that the money arrived in his account just days later, even before the paperwork was completed or the company officially registered.

The founder recalled on 20VC that he could hardly believe the transfer when he received the bank notification, describing it as one of the most defining moments of his life.

The million dollar leap that turned into a billion

What followed is now startup folklore. As reported by Forbes, that initial one million dollar cheque turned into roughly one billion dollars in value as Airwallex scaled at remarkable speed and became Australia’s fastest growing unicorn, backed by major global investors and serving more than 150,000 customers.

Airwallex, now nearing decacorn status with a valuation of 6.2 billion US dollars, has disrupted legacy systems like SWIFT and expanded into business accounts, expense management and multi currency cards. Forbes notes that Lucy Liu is one of only two women in Australia to co found a company approaching ten billion dollars in value.

From finance graduate to fintech visionary

Liu, who initially only intended to explore investing, went on to become co founder and president of Airwallex. Forbes reports that she saw the investment as a learning opportunity and a way to build something meaningful rather than follow a predictable corporate path. That conviction helped shape one of the most influential fintech platforms of the decade.

Zhang described her decision as more than financial support, calling it a powerful vote of confidence that propelled the company’s early growth.

What started as a spontaneous conversation among three University of Melbourne graduates evolved into a multibillion dollar disruptor aiming to build what Liu calls the future of global finance.
