Every β
AI-powered US business incorporation and compliance service handling LLC formation, EIN, bank setup, and ongoing filings for startups.

Firstbase handles the legal and administrative overhead of starting a US company: incorporation, EIN setup, business bank account access, compliance filings, and ongoing management in one dashboard. It automates the paperwork for forming a company in Delaware or Wyoming, including expedited Tax ID (EIN) setup and zero filing fees for all required documents.
Beyond formation, Firstbase bundles essential documents, banking partner access, and tools to get discovered by VCs. Its Firstbase One subscription adds compliance reminders, annual report filings, a registered agent, premium mailroom service, integrated accounting, and tax filing for LLCs and C-Corps.
Ideal for international founders incorporating a US company for the first time, early-stage startups that want to avoid legal fees for routine filings, and founders who want incorporation, compliance, and accounting handled in one place.
