Founded in 2012 by two Stanford students, Snap is the Los Angeles-based technology and social media company behind messaging app Snapchat.
Snapchat is a photo-messaging application developed by Evan Spiegel and Jonathan May. Snapchat allows users to take photos or record videos, then add text and drawings and send them to a controlled list of recipients. Users set a time limit for how long recipients can view their snaps. After the viewing, snaps are hidden from the recipientâs device and deleted from Snapchatâs servers. Latest.
