The global video game industry is thriving. According to PwC, gaming is expected to grow from $71.3 billion in 2015 to $90.1 billion by 2020. Jason Citron, the CEO and founder of Discord, understands this space very well. He started gaming on the NES when he was five, learned how to program games in high school, founded and sold a social platform for mobile games, and is now building a messaging platform for gamers.

Greylock investment partner Josh Elman caught up with Jason to talk about his entrepreneurial journey, the gaming industry, and what's in store for Discord.
