Nikita Bier is stepping down as head of product at X, according to multiple reports. TechCrunch says Bier leaves the role a little over a year after taking on what it describes as a 24/7 responsibility overseeing the platform. Rappler reports that Bier announces his departure in an X post, saying that “running this app is a 24/7 job” and that it is time for him “to take a breather.” The coverage does not provide details about a replacement or an immediate transition plan. It also does not cite an official company statement beyond Bier’s own post. Overall, the reports indicate the move is voluntary and tied to workload and personal time rather than to any specific performance issue mentioned in the sources.
