According to Recode, Kroll was fired from Twitter for poor management, and had earned a reputation for inappropriate behavior toward women.

When this came to light in 2018, Kroll said in a statement, "I was let go from Vine four years ago for poor management. It was a painful experience, but an eye-opening one that served as a catalyst for professional development and greater awareness in the office. I now realize that there are things I said and did that made some feel unappreciated or uncomfortable. I apologize to those people."

HQ Trivia a live, game show-style quiz app launched in August 2017 with Kroll serving as chief technology officer.

The app was an instant viral hit, thanks in part to its silly, charismatic host and the ability to win real cash prizes. Earlier this year, the app was at the top of the App Store charts for weeks at a time.

But just as quickly as the app went viral, its popularity faded and it faced internal turmoil of its own. In September, the company reportedly forced out Yusupov as CEO and replaced him with Kroll. And shortly before Kroll was appointed CEO, an HQ Trivia employee reportedly filed a complaint over Kroll's "aggressive management style."

Despite HQ's issues, the company had announced plans for a second "Wheel of Fortune"-style game and has been earning money off sponsorship deals and in-app purchases.

HQ closed a $15 million funding round in March and is expected to do $10 million in revenue in 2018.
