What a difference a year can make. One year ago, anonymous messaging app After School was in the middle of a four-month-long ban from Apple’s App Store for violating the company’s safety guidelines.

Now After School is alive and well, and cashing a really big check.

The company, which has an app for high school students to post anonymously to their classmates, raised $16.4 million in a new round of venture funding led by Accomplice. The round includes other investors like Cowboy Ventures and individuals like Parse co-founder Tikhon Bernstam and AngelList founder Naval Ravikant.
