The launch of stickers on the Web Tuesday was the last hurrah for their designer, as TechCrunch reported that Sophie Xie is leaving Facebook.

According to TechCrunch, Xie launched the stickers initiative at one of the social network’s hackathons, and she is leaving the company to work on a hyperlocal location application.

Xie had been with Facebook since 2012, according to TechCrunch.
