Medium began in San Francisco as a product of Obvious Corporation, the company founded by Evan Williams and Biz Stone after Twitter, and its first major infrastructure and community were established there.
As the platform grew, Medium expanded its engineering and operations into additional U.S. hubs and later into international locations, shaping today’s distributed system that supports millions of readers and writers worldwide.
This overview explains the origins of Medium, how its headquarters and offices have evolved, where its core engineering and content operations live now, and what that means for the platform’s long-term roadmap and reliability.
Origins and Founding Location
Medium launched in August 2012 as a project inside Obvious Corporation, a San Francisco–based company founded by Evan Williams and Biz Stone.
Because it emerged from Obvious, Medium’s earliest engineering, design, and product decisions were made in the Bay Area, and early employees and creators were primarily based there.
San Francisco remained the public-facing symbolic home for Medium through its first decade, even as the company expanded teams and responsibilities elsewhere.
First Headquarters at 585 Howard Street
Medium’s original headquarters were located at 585 Howard Street in San Francisco, a few blocks from the Twitter headquarters where Williams and Stone had previously worked.
This address became the operational nucleus where the initial product was refined, early partnerships were formed, and the first version of Medium’s publishing tool was built and iterated.
Transition to 1455 Market Street
By the mid-2010s, Medium moved its primary San Francisco office to 1455 Market Street to accommodate a larger workforce and more specialized teams.
The relocation reflected product milestones including the introduction of Medium Member Program, expanded curation, and deeper analytics for readers and publications.
Engineering and Product Headquarters
Over time, Medium’s engineering organization became distributed, but the core product and platform teams remain concentrated in two primary U.S. locations.
The company continues to operate a substantial presence in the San Francisco Bay Area, while a significant engineering and product hub is located in Seattle, Washington.
San Francisco Bay Area
The Bay Area remains the home of Medium’s product management, design, trust and safety, and many platform reliability teams.
Offices there focus on user experience, creator tools, content operations, and coordinating the roadmap across markets.
Seattle
Medium’s Seattle engineering team handles much of the backend infrastructure, performance, scaling, and reliability work.
This includes content delivery, database systems, search, and the services that keep Medium running at global scale.
Global Infrastructure and Data Centers
Behind the scenes, Medium relies on cloud infrastructure and global data centers to serve readers and writers in every region.
The platform primarily runs on cloud providers with multiple points of presence, allowing it to scale traffic, reduce latency, and maintain redundancy.

International Presence and Remote Work
Medium supports a globally distributed readership, and its teams are spread across time zones.
While many high‑level decisions and strategy happen from U.S. offices, contributors, engineers, and community teams are located worldwide.
The company maintains remote-friendly policies in many roles, allowing talent to be sourced from multiple regions without requiring a single physical headquarters for all functions.
Content Operations and Trust & SafetyWhere Moderation and Curation Happen
Content operations, including curation, partnership management, and policy enforcement, are organized across multiple locations.
Some teams are colocated in San Francisco and Seattle, while others work from remote or regional locations to support local languages and communities.
Reliability and Site Infrastructure
Reliability engineering, database operations, and deployment pipelines are centered largely in Seattle and cloud control planes.
These teams manage uptime, incident response, and the infrastructure that underpins the editor, the recommendation feed, and the publishing flow.
Comparative Overview: Where Medium Runs and Who Builds It
| Location | Primary Focus | Role in Medium’s Stack |
|---|---|---|
| San Francisco, CA | Product, design, trust & safety, content operations | Product strategy, creator programs, community governance |
| Seattle, WA | Engineering, reliability, backend services | Platform infrastructure, scaling, search, databases |
| Cloud Regions (Global) | Content delivery, data replication, edge caching | Global distribution, low-latency reads, backups |
| Remote/Regional Teams | Localization, support, specialized engineering | Language-specific content, regional integrations |
Evolution and Future Outlook
Medium’s infrastructure has evolved from a single-product startup in San Francisco to a multi-region, cloud-native platform.
As the company continues to invest in performance, reliability, and creator tools, its operational footprint may expand into new regions or deepen automation.
Throughout these changes, the core mission of serving long-form writing and thoughtful conversation remains anchored in the locations and teams that originally built the product.
