Gusto Headquarters Address, Corporate Office Location, and Contact Details

About

Gusto, Inc. is an American HR technology and payroll SaaS company headquartered at 525 20th Street, San Francisco, California 94107 — a purpose-designed 55,000 square foot office inside the historic American Industrial Center (Pier 70 area) in San Francisco’s Dogpatch neighborhood, a former shipbuilding hub that blends industrial architecture with modern collaborative workspaces. Gusto was founded in 2012 under the name ZenPayroll by Josh Reeves, Tomer London, and Edward Kim — originally as a simplified payroll platform for small businesses — before rebranding to Gusto in 2015 to reflect its broader expansion into HR, benefits, and compliance services. The company is privately held and has raised over $750 million in venture funding.

Gusto’s platform serves 400,000+ small and medium-sized businesses across the United States, providing payroll processing, health benefits administration, 401(k) plans, HR tools, onboarding, and compliance support — all in one integrated platform. In addition to its San Francisco headquarters, Gusto maintains key offices in Denver, CO (1201 16th Street, Suite 350 — Tabor Center), New York, NY (450 Park Avenue S), Scottsdale, AZ (14350 N 87th Street), and Istanbul, Turkey. The company employs approximately 2,600+ people with a hybrid work model of roughly two days per week in-office.
