Nikita Bier resigns as Head of Product at X

“Ladies and gentlemen, it's time to pass the torch and demote myself to my natural state: a poster. I'll be stepping back from leading product for 𝕏 and will continue on as an advisor,” he wrote.

“Serving the X community has been the privilege of a lifetime. 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,” Bier continued. “The app is seeing unprecedented growth in new users & engagement. We continue to break records every month. We've climbed 70 spots in the App Store since this time last year. And in the last 400 days, we rebuilt almost every aspect of X: the Timeline, the Android app, onboarding, notifications, chat and more.”

Bier highlighted achievements made by the company under his leadership, pointing to the popular feature on the platform that shows country-of-origin for profiles.

“We also launched nearly 30 new products while protecting the integrity of the town square: becoming the first app to show Country-of-Origin on profiles and mounting defenses against AI bots. There's certainly much more work to be done, but our foundation is stronger than ever,” he said.

Bier thanked X owner Elon Musk and said that the next leaders of the platform will take X to “even greater heights.”

The resignation marks the end of Bier’s one year as head of product after he assumed the role in July of 2025. During his tenure, he became one of the platform’s most visible executives, regularly interacting with users on X and responding to feedback and suggestions.
