Founded in 2012 by two Stanford students, Snap is the Los Angeles-based technology and social media company behind messaging app Snapchat.
Snapchat is trying to clean up its act after the recent leak of thousands of usersâ pictures. Back in October, in an event dubbed The Snappening, as many as 200,000 snaps were leaked from the hugely popular picture-sharing app, shocking its users.napchat denied any responsibility for the leaked pics, blaming the catastrophe on a third-party app that allowed its photos to be stored indefinitely. But no-one really remembers the name of that guilty app (it's Snapsaved) â it's only the name of Snapchat that has been tarnished by the whole affair.
