A few months ago, Kayvon Beykpour met a fellow Stanford University graduate, Jessica Verrilli, for coffee.

Verrilli is the Director of Corporate Development and Strategy for Twitter. She asked what Beykpour had been working on since leaving Blackboard, an education company that had acquired his prior startup, TerriblyClever. Beykpour fired up his iPhone and showed her Periscope.
