​Vine and HQ Trivia Co-Founder Colin Kroll Dead at 34
Colin Kroll, the co-founder of Vine and app-based trivia game HQ, was found dead yesterday (December 16) of an apparent drug overdose. He was 34.
Police found Kroll unresponsive in his Manhattan apartment after a woman he was with called 911, and confirmed that a drug overdose is the suspected cause of death. An investigation is currently underway.
Kroll co-founded Vine in 2012. The popular six-second video platform was acquired by Twitter, but was shut down in 2016. Kroll was reportedly fired by Twitter for "poor management behaviour" and inappropriate behaviour toward women.
He went on to co-found the trivia game HQ. The app launched in 2017 and became wildly popular, racking up a high of 2 million concurrent players, but the number of users drastically dropped to just hundreds of thousands last month.
According to Time, Kroll was facing allegations of inappropriate workplace behaviour at HQ, as well.
