Nikita Bier has stepped down as head of product at X, transitioning to an advisory role after leading a major overhaul of the social media platform’s core experience. In a post on X, Bier described leading product at the company as “the privilege of a lifetime,” but said the role had become a “24/7 job” and that it was time to “take a breather.” Before joining X, Bier had already established himself as one of Silicon Valley’s most successful consumer app founders. He created the viral social app TBH, which was acquired by Facebook in 2017, before launching Gas, an anonymous compliments app for teenagers that was acquired by Discord in 2023. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor.
