For founders setting up a U.S. company, including those launching from abroad, Firstbase brings incorporation and business administration into one online workspace. Use it to form an LLC or corporation, request an EIN, and prepare company documents. The platform also provides access to registered-agent and business-address services, plus tools to track compliance filings and deadlines. After formation, founders can use Firstbase Loop to apply for services such as business banking, payment processing, payroll, and accounting through partner providers. Firstbase also offers bookkeeping and payroll-tax registration services for companies managing finances or hiring employees across states. It may suit founders who want help with both company setup and ongoing U.S. business administration; partner services, such as bank accounts, require separate approval.
