X product chief Nikita Bier is leaving after one year

Nikita Bier, X’s head of product, is leaving the role just over a year after joining and will become an advisor. He said much of X was rebuilt during his tenure, including the timeline, Android app, chat, and notifications, while new leaders will take over design and product responsibilities.

The departure adds another leadership change at X during a period of rapid product reshaping under Elon Musk. It suggests X is moving from a rebuilding phase toward execution under a broader leadership bench, but continuity could be a challenge for its product roadmap.
