What Does Twitter Do?
X (formerly Twitter) is a global social media and microblogging platform owned by X Corp. It allows users to post and interact with messages known as 'posts' (formerly 'tweets'). Since its acquisition by Elon Musk in October 2022, the platform has been undergoing significant transformations with an ambition to become an 'everything app,' integrating features beyond social networking, such as payments, long-form content, and video. X remains a prominent platform for real-time information dissemination, news, public discourse, and connecting people and businesses worldwide.
Where Is Twitter's Headquarters?
HQ Function
Serves as the primary global headquarters for X Corp., housing core operations including engineering, product development, executive leadership, policy, and global strategy teams.
Notable Features:
Located in the historic Art Deco Market Square building (formerly the Western Furniture Exchange and Merchandise Mart). The office space was known for its expansive layout, various amenities, and collaborative workspaces. Post-acquisition, physical office space utilization has been consolidated.
Work Culture:
Historically, Twitter was known for a vibrant tech company culture with numerous employee perks and a focus on open communication. Post-acquisition by Elon Musk, the culture has shifted towards a more 'hardcore' engineering-driven environment, emphasizing high intensity, longer hours, and rapid iteration. Significant workforce reductions have also impacted the atmosphere.
HQ Significance:
The San Francisco HQ symbolizes X's origins as a transformative social media platform and its current phase of radical change under new ownership. It remains a key center for innovation and decision-making for the platform's future.
Values Reflected in HQ: Previously, the HQ design aimed to reflect values of transparency, community, and employee well-being. The current operational ethos, and by extension the HQ's functional focus, reflects values of lean operations, speed, and a 'first principles' approach to product development.
Location:
X operates globally, serving users and advertisers across most countries. While its physical office footprint has been consolidated since 2022, key functions like engineering, sales, policy, and trust & safety are supported by teams operating from remaining strategic locations in North America, Europe, and Asia-Pacific, as well as through remote work. The platform's infrastructure is distributed worldwide to ensure service availability and performance for its global user base.

What Leadership Changes Has Twitter Seen Recently?
The most significant executive change in the last 12-18 months was the appointment of Linda Yaccarino as CEO in June 2023, following a period where Elon Musk served as interim CEO after the acquisition in October 2022. The acquisition itself led to the departure of the previous executive team. Since Yaccarino's appointment, the leadership team has been relatively stable at the top, though changes may have occurred at VP levels.
