Sea Limited, the leading online gaming and shopping platform in Southeast Asia, made its market debut on the New York Stock Exchange Friday. After pricing the IPO at $15, shares opened for trading at $16.25. During the day, they rose as high as $17, fell back down to $14 and then rebounded at the end of the day. Just after shares opened, the company's Group President Nick Nash stopped by to discuss the big opportunity for the Singapore-based company. Focused on the long-term opportunity, Nash explains why the growth of smartphones in Southeast Asia is an advantage for the company. Nash also talks about Sea's secret weapon, AirPay. AirPay is its digital financial services platform that is quickly being integrated into its other platforms. Sea counts China's Tencent as its biggest shareholder. Nash says its mentorship is a key to the company's success.
