X Product Head Nikita Bier Claims Core Application Rewrite Will Accelerate by 90%
Nikita Bier, head of X product, stated that the company has rewritten almost all core application components over the past 12 months.
These backend optimizations are invisible to users, but an upcoming update will reduce web application loading times by 90%, aiming to significantly enhance platform performance and user experience.
This engineering iteration focuses development resources on infrastructure optimization, benefiting users and developers on the event-driven X platform with faster responses. Competitors face pressure on loading efficiency due to an expanding technological gap, while long-term projects within the X ecosystem gain valuation support.

Nikita Bier, as the head of X product, previously founded TBH (acquired by Meta) and Gas (acquired by Discord), known for viral growth strategies. After joining X, he focused on Grok integration and timeline relevance optimization, driving multiple backend and creator tool iterations to revitalize platform growth.
In terms of capital strategy, X continues to invest engineering manpower and computing resources into a full-stack rewrite, leveraging invisible performance optimizations to enhance user retention and advertiser budgets. The strategic motive is to improve the foundational experience in response to the AI content surge, while laying a high-performance base for future agency and payment functionalities to capture long-term traffic monetization.
This aligns with ongoing investments by Meta and ByteDance in Feed algorithms and loading optimizations, as well as early Twitter's architectural evolution from Ruby to Scala, consistent with the current social platform transition from feature expansion to extreme performance and AI-native stages.
Essentially, this is a technological replacement: rewriting core components accelerates the transition from traditional architectures to modern efficient systems, mechanism-wise concentrating user attention and advertising capital on the X platform through performance leaps, strengthening network effects and building high entry barriers to avoid being replaced by faster competitors in AI-driven content distribution.

Visible features attract traffic, invisible performance builds fortifications, top products always win in the background.
Rewriting core is not a gimmick; a 90% speedup translates to user stickiness, structural leverage stems from the invisible.
Most chase new features, few lock in foundational experiences; winners sell speed rather than the functionality itself.
