Twitch launched in June of 2011, and our growth ever since has exceeded even my expectations, which were not small. A year and a half later, the community of broadcasters and viewers has multiplied hundreds of percent.

Who would you talk to? That is the first question for almost any startup that you need to answer. Who is my user and where am I going to find them?

You want to learn about what's already in their heads. You want to avoid putting things there.

It's one of the most validating things you can do for a product is go out there and get them to commit to pay you up front.

The Twitch community loves watching video games, chatting, and broadcasting. The average viewer watches over an hour and a half of video each day. Over two-thirds of our logged-in users chat each day.

The most interesting things you learn in an interviews come from the: 'interesting', 'tell me more'

If you just talk to who's easy to talk to, you're not really getting the best data.
