Australia-based cross-border payments startup Airwallex has closed a $13 million Series A round to expand its reach across Asia Pacific and into Europe. The deal was led by Chinese internet giant Tencent — marking its first investment in an Australian startup — with participation from Sequoia China, Mastercard and other undisclosed investors.
