YIK YAK: $10 million to Atlanta, GA-based Yik Yak in a Series A round led by DCM, with Azure Capital Partners, Renren Inc. (a Chinese equivalent of Facebook) and Tim Draper also participating. The anonymous social messaging app was initially designed as a "college Twitter feed," but quickly picked up traction among younger students. It gained notoriety as a cyberbullying tool, leading the company to use geolocation technology to block the app from being used in K-12 schools. BusinessInsider reports the app is "used heavily (by thousands of students) on about 250 campuses."
