Founded in 2012 by two Stanford students, Snap is the Los Angeles-based technology and social media company behind messaging app Snapchat.
In late March of this year, Snapchat 2.0 launched, which massively expanded the app's private messaging capabilities â and that's where the snapstreak stuff comes in.
