Periscope changed how we see the world. Periscope is a live video streaming app developed by Kayvon Beykpour and Joe Bernstein. The idea for Periscope was born in 2013, as Kayvon traveled abroad. He was in Istanbul when protests broke out in Taksim Square. He turned to Twitter for real-time updates but, while he could read about the protests, he was frustrated not to see them. Motivated by that experience, Kayvon and Joe started the company in February 2014. Two months later, we provided seed capital to fund development of the app. Before launching their product, Periscope was acquired by Twitter (January 2015). Periscope was launched in March 2015 and now has over 10 million registered users and 40 years of video watched per day.
