I don't use Snapchat, so correct me if I'm wrong, but aren't those relatively new developments? From a quick Google search, it seems that the acquisition of Looksery and the launch of "Snapchat Lens" didn't occur until September 2015. By then, Snapchat already had at least 80 million daily active users. While their current real time computer vision stuff is definitely not something the average engineer could make, it does seem like they started out as a cookie cutter app.
