Unrest

Your university has thousands of students. Most of them never meet.
Unrest is a social app that tries to fix that. You get a feed for posting whatever's on your mind - anonymously if you want, or under your name.
You get Corridor, which matches you with students who share your interests and goals, not just your college or year. You also get a practical tab for things like finding study spots, asking seniors about placements, or just figuring out what's open near you at 9pm.
It's exclusive to students at your university, which is the point. A smaller network where everyone shares the same context is more useful than a large one where nobody does.
