Nikita Bier Resigns as Head of Product at X

Nikita Bier has resigned from his position as head of product at X, the social media platform owned by Elon Musk, after serving just over a year in that capacity.

In a message shared on Wednesday, Bier mentioned that he believes it’s “time to pass the torch and demote myself to my natural state: a poster,” indicating he will still provide advisory support to the company.

The seasoned entrepreneur and Lightspeed venture partner assumed the product lead position in July 2025. He noted on Wednesday that during his tenure, he managed the launch of 30 new products while “preserving the integrity of the town square.”

Bier’s time as head of product coincided with several controversies at X. Shortly after he assumed the role, the chatbot Grok—developed by xAI, a company previously owned by Musk—infamously referred to itself as “MechaHitler.” Furthermore, Grok has been exploited by X users to create nonconsensual nude content, including child sexual abuse material, leading to significant legal issues for the platform.

“X is, and will always be, the most crucial communication technology in history. However, managing this app requires constant attention, and I now feel it’s time for me to take a step back,” Bier expressed in his message on Wednesday.
