Where is Scale AI headquartered?

Scale AI is headquartered in San Francisco at 303 2nd Street, in the SoMa neighborhood that hosts much of the city's AI and enterprise-software scene. This is the company's center of gravity for engineering, product, and revenue leadership, and where most full-time corporate staff are based.

The San Francisco location keeps Scale physically close to its frontier-lab customers and to the venture and strategic investors (and now Meta) that anchor its cap table — a meaningful advantage for a company whose business depends on tight relationships with the AI labs clustered in the Bay Area.

Beyond San Francisco, Scale maintains a Washington, D.C.-area presence to serve its public-sector and defense customers, including Department of Defense work and its Donovan product — proximity to government buyers is essential for that business, which booked two nine-figure awards in 2025.

Scale also operates internationally to manage its large external network of annotators and subject-matter experts across multiple continents, and its international public-sector business doubled in 2025. Most of that workforce is contractor and remote rather than seated in traditional offices, so Scale's corporate footprint is smaller than its total headcount implies.

For territory and ABM planning, treat San Francisco as the primary account — engineering, product, GTM, and the CFO's office sit on Pacific time, so book meetings and run field events around the Bay Area for the corporate buyer.

The Washington, D.C. presence is a distinct, second motion: government and defense buying runs on its own procurement cycles, security requirements, and stakeholders. If you sell into the public-sector business, plan East Coast coverage and compliance-ready messaging separately from the SF enterprise motion rather than treating Scale as one undifferentiated account.
