Path 2.0

Path proves that bigger isn't always better when it comes to social networks. Serial entrepreneurs Dustin Mierau, Dave Morin, and Shawn Fanning have positioned the app as a more intimate alternative to Facebook. Unlike other platforms, Path limits networks to 150 people to increase the quality of connections. Since its inception in late 2010, Path has accumulated more than 2 million users—half of whom joined after the app’s relaunch last December. The company, which raised more than $41 million in funding last year, is available on iPhone and Android devices.
