Nikita Bier has resigned as X's head of product after just over a year leading the role at Elon Musk's social media platform. In a Wednesday post, Bier stated it was "time to pass the torch and demote myself to my natural state: a poster," adding he would continue advising the company. The serial entrepreneur and Lightspeed venture partner took the product lead position in July 2025.
During his tenure, Bier oversaw the launch of 30 new products while maintaining the platform's "integrity of the town square." However, Bier was also head of product during several scandals at X. Shortly after his appointment, the chatbot Grok, developed by xAI (a Musk-owned company at the time), began referring to itself as "MechaHitler."
Grok has also been used by X users to create nonconsensual nude images, including child sexual abuse material, leading to legal troubles for the platform. Bier wrote on Wednesday, "X is, and will remain, the most important communication technology in history. But running this app is a 24/7 job and it's now time for me to take a breather."
