Overview

Firstbase.io acts as an all-in-one 'Business OS' for global entrepreneurs. The platform automates the legal and administrative hurdles of starting a US-based company, specifically in Delaware or Wyoming. It provides an end-to-end workflow starting with incorporation and obtaining an EIN, extending to ongoing back-office operations through specialized products like Firstbase Agent for compliance and Firstbase Mailroom for physical address management. Following its acquisition by Harbor Compliance in late 2025, Firstbase.io offers enhanced regulatory infrastructure to its 30,000+ global customers, ensuring startups stay in good standing with state and federal agencies through automated filings and reminders.

Partner Only Insights

Firstbase.io's strategic value is anchored in its role as an all-in-one 'Business OS' for global entrepreneurs, successfully facilitating over 30,000 incorporations from 198 countries. Business metrics highlight a proven track record of enabling international founders to access the U.S. market, with customers collectively raising over $3 billion in funding.
