FORBES - Dec 19 - As an MBA student at the University of Chicago, Paktor CEO and co-founder Joseph Phua learned the first-hand benefits of online dating. He returned to Singapore to launch an American-style mobile dating app. The Paktor team soon found that successful tactics used by US and European dating apps didn't translate to Asian societies because of their more conservative dating norms. So Paktor launched Group Chats (providing an environment to facilitate chats within a collective community). The app has now ~15M users, 5B swipes and the largest activity in the region by downloads and usage. They achieved this growth by deeply understanding their local customers and deploying Facebook's Account Kit to enable mobile phone numbers as a universal login.
