Snapchat

Snapchat is buying Bitstrips, the company behind the Bitmoji app that lets you create an avatar of yourself to share on social media and over text, according to a source familiar with the deal.Fortune’s Dan Primack, who first reported the news, said Snapchat is paying “in the ballpark of $100 million” for the company, which was founded in 2012. It quickly became popular on Facebook, as users created and shared cartoon versions of themselves in a bunch of different settings.
