The TL;DR version: In 2007, Justin.tv began simply with Justin Kan lifecasting himself from his startup’s dorm style living quarters in the Y-scraper. It didn’t take long for Justin’s audience to start directing the show. The founders were able to get the cost to deliver one hour of video down to half a penny, so Justin.tv pivoted to an open, ad-supported live streaming platform. Traffic grew immensely, aided by some users illegally simulcasting blacked out pro sports events from around the world. A boxing promoter and UFC went on the attack, while Michael Seibel, Justin.tv’s CEO, had to answer to Congress. Overall traffic declined as video game streaming traffic increased. Taking this cue, TwitchTV was spun off to create a streaming platform built exclusively for video gamers to broadcast game competitions. With the rise of mobile apps, Socialcam soon became another successful spin-off. Socialcam is a mobile video sharing app that leverages Justin.tv’s infrastructure, now with 44 million users. Not to be outdone, Justin had to go and found yet another startup. Exec is a service that helps match users with personal assistants to get specific tasks done.
