Seven years ago, Airwallex co-founder Jack Zhang declined Stripe's offer to acquire his company for 1.20 billion USD. At that time, renowned investor Michael Moritz also advised him to accept the deal. After weeks of discussing details and pricing with Stripe co-founder Patrick Collison, Zhang was nearly convinced, but ultimately, he and the three co-founders voted via a WhatsApp call to reject the offer. Since then, Airwallex has grown significantly, and the founders have accumulated wealth of 775 million USD.
