Nikita Bier steps down as X head of product after a year, returns to advisory role

Nikita Bier, the serial entrepreneur who joined X as head of product in mid-2025, has stepped down from the role after a little more than a year. He announced the move on August 5, 2026, saying he will continue as an adviser to the platform owned by Elon Musk.

Bier, known for creating the viral apps TBH and Gas, took the job in July 2025 and described it as a "24/7 job." His departure comes just over a month after he celebrated his one-year anniversary at the company, according to The Verge.

From viral apps to X's product chief

Bier's tenure at X was marked by his role as the face of several major product changes. He was involved in pushing features that leaned into the platform's creator economy and engagement tools, though specific details of his projects were not always public. His background as a consumer app builder made him an unusual pick for the role, but Musk has often favored founders over traditional product managers.

• Bier founded TBH, a polling app acquired by Facebook in 2017, and Gas, a similar app acquired by Discord in 2023.
• He joined X in July 2025, according to TechCrunch, and his one-year anniversary was celebrated in late July 2026.
• His departure was first reported by TechCrunch and picked up by Engadget and The Verge.
• He will remain as an adviser, a role that allows him to stay involved without the day-to-day grind.

What Bier's exit signals for X

Bier's step-down is the latest in a series of leadership changes at X since Musk acquired the company in 2022. The platform has seen high turnover in product and engineering roles, and Bier's departure adds to that pattern. His decision to stay as an adviser suggests he remains on good terms with Musk, but the move raises questions about who will lead product strategy next.

In his announcement, Bier wrote that "it's time to pass the torch and demote myself to my natural state: a poster," a nod to his active presence on the platform. He did not name a successor, and X has not publicly commented on the transition. For now, Bier's focus shifts back to his own projects, and the platform will need to find a new product leader to carry forward its ambitious plans.
