Justin Kan's epic year: Selling Twitch for $1B, joining Y Combinator, and building an art car

VIENNA, Austria — By anyone’s definition, Justin Kan has had a monster year in 2014.

It started with Kan selling his startup Exec to Handybook in an all-stock deal (the amount was undisclosed). Then, in June, he joined Y Combinator as a partner. And finally, in August, Amazon spent $970 million to acquire Twitch, the third iteration of a company Kan started in 2007 as a lame Internet reality TV show starring himself.
