After a two and a half years, HQ Trivia — the live game-show app that gave away cash prizes to winners — is shutting down.

HQ Trivia’s shutdown was first reported by CNN. The company is laying off its 25 full-time staffers, according to the report. Reps for the company did not immediately respond to a request for comment.

The app was launched by parent company Intermedia Labs in August 2017. At its peak HQ Trivia — which spawned a rash of copycats — had attracted some 2.3 million live viewers, each looking to earn a piece of a steadily growing pool of prize money.

Intermedia Labs was co-founded by Rus Yusupov and Colin Kroll, two of the creators of Vine, which Twitter acquired in 2012 and then shut down four years later. In December 2018, Kroll was found dead in his New York City apartment of an apparent drug overdose. The company had been led by Yusupov.

In 2018, Intermedia raised $15 million in funding led by venture-capital firm Founders Fund, with participation from Lightspeed Venture Partners, which previously invested seed money in the startup.

HQ Trivia had inked ad deals with several entertainment companies, including Fox, Warner Bros., NBC and Universal Pictures, as well as Google, Nike, Target, JPMorgan Chase, and MillerCoors.
