<p>Spotted in Startup Alley at TechCrunch Disrupt SF 2013, Uni Messenger is a new cross-platform mobile messaging application that lets you chat privately with friends on a variety of social networks, including Facebook, Twitter, LinkedIn, Sina Weibo, Tencent Weibo, VK, Mixi, Cyworld, and now, the team is working to add support for Google+ and several others.</p><p>The company was founded just this June by David Huning Dai, a Columbia Computer Science grad, and previously founder of social network analytics service JoyRec, along with Joe Huaqiao Chiu, who had been working on a cross social networking communications platform in China back in 2011.</p><p>Today, Uni Messenger has eight full-time employees, and nearly a dozen part time staff based in San Francisco.</p><p>The service, expected to launch in October (for early access, see below), is a downloadable application being built for Android first which combines all your social networking contacts into one address book. This part of the service is similar to a number of competing social address book apps, like Brewster, Cobook, Addappt, and others. But once installed, users will be able to message their friends on the various social networks using just the app.</p><p><a href="http://techcrunch.com/2013/09/11/uni-messenger-is-a-cross-platform-cross-social-network-mobile-messaging-app/">Keep reading...</a></p>
