BuzzFeed News has learned that just over a year after it debuted, Secret — the anonymous social app that made headlines around the world as a possible harbinger of truly anonymous social networking — is closing shop.

David Byttow, Secret's founder and CEO, notified employees on Tuesday and began the process of issuing severance packages, sources tell BuzzFeed News. Byttow has not returned requests for comment.

Once a hotbed of Silicon Valley gossip, Secret has been losing momentum since its high-profile launch. The app has reportedly been hemorrhaging users as of late and, at the end of 2014, underwent a major redesign, favoring text-only posts rather than photos.
