Nikita Bier, a tech entrepreneur behind viral social media apps like tbh and Gas, has been appointed Head of Product at X, Elon Musk’s rebranded version of Twitter. The announcement was confirmed by Musk and celebrated by Bier, who has been an active user and builder in the X ecosystem.
“Ladies and gentlemen, I've officially posted my way to the top,” Bier declared in a post on X. “X is the most important social network in the world. It's where internet culture originates and where the world's most influential people convene.”
Bier emphasised his deep personal connection to the platform, sharing how it shaped both his professional and personal life, even leading to him meeting his girlfriend. He expressed excitement about helping others experience similar value by using artificial intelligence tools like Grok to create smarter timelines and boost content relevance.
Bier brings a strong product development background. He co-founded tbh, a positive polling app acquired by Facebook (now Meta) in 2017. After a stint at Meta as a product leader until 2021, he went on to co-create Gas, an anonymous polling app aimed at teens that achieved rapid user growth.
Since early 2024, Bier has been embedded at xAI, Musk’s artificial intelligence venture, where he quietly worked on integrating AI features into X. His recent efforts have included tools that use AI to generate context-aware questions for user engagement.
As X continues to evolve into an AI-enhanced super-app under Musk’s leadership, Bier’s appointment signals a push to merge community-driven design with advanced personalisation.
