Tumblr
Tumblr's Overview
Tumblr is an American microblogging and social networking website founded by David Karp in 2007. It is currently owned by Automattic. The platform allows users to post multimedia and other content to a short-form blog, follow other users' blogs, and customize their blog's appearance. Tumblr is known for its vibrant communities, creative expression, and diverse content, ranging from art and photography to GIFs and text posts. It provides a space for users to discover and share content aligned with their interests.
Where is Tumblr's Headquarters?
HQ Function
Historically, the New York office was the central hub for Tumblr's operations, including engineering, design, product development, marketing, and community support teams.
Notable Features:
The former New York office was known for its creative, open-plan design, reflecting the platform's vibrant community. It often featured art installations, communal areas, and spaces designed to foster collaboration and innovation.
Work Culture:
Under Automattic, Tumblr's work culture is remote-first, emphasizing autonomy, trust, flexibility, and asynchronous communication. Historically, Tumblr's NYC office culture was recognized for being innovative, fast-paced, inclusive, and deeply connected to internet culture and creative communities.
HQ Significance:
The New York City location was significant as it positioned Tumblr at the heart of a major global hub for technology, media, and art, which was crucial for talent acquisition and brand development during its formative and growth years.
Values Reflected in HQ: Historically, the NYC office design and culture reflected values of creativity, community engagement, and openness. The current distributed model under Automattic reflects values of autonomy, global collaboration, inclusivity, and work-life balance.
Location:
Tumblr's platform is accessible globally, catering to a diverse international user base and content creators from nearly every country. As part of Automattic, a distributed company, its team members are located across different continents and time zones.
