Kevin Systrom and Mike Krieger sold Instagram to Facebook more than two years ago. Why are they still there?
Because it’s interesting! The co-founders shared some of what keeps them busy during an interview with Kara Swisher and Liz Gannes at Code/Mobile.
For starters, what used to be a tiny company (about a dozen employees and 45 million users) is now pretty big (70 employees and 200 million users). And while Instagram’s core product looks the same to outsiders — an app that lets users share photos in a square frame with other people who have the app — they’ve added all kinds of features, like video and messaging.
