Visit Firstbase →Starting a business comes with a long checklist of legal and administrative tasks that have nothing to do with the actual work of building it. Firstbase puts incorporation, compliance, bookkeeping, and taxes under one roof so founders can get the setup right without losing weeks to paperwork.
Firstbase is an all-in-one business operations platform built for founders — US-based and international alike. It handles company formation, registered agent services, compliance, bookkeeping, tax filing, payroll registration, and more through a single platform trusted by over 30,000 companies across 191 countries.
Firstbase Start automates the entire company formation process, letting you incorporate an LLC or C-Corp without legal headaches or manual paperwork. It handles the filing, walks you through the process, and gets your company set up properly from day one.
Beyond formation, Firstbase covers the ongoing operational layer that trips up a lot of founders. The Agent product handles registered agent requirements, annual reports, and state compliance automatically. The Mailroom gives you a real US business address and a virtual mailbox to manage business mail in one place — useful for remote founders who don't have a physical US presence.
Firstbase Accounting and Tax Filing round out the platform with bookkeeping, financial reporting, and corporate tax returns handled for you. For companies hiring across multiple states, the Payroll registration product takes care of state and city-level registrations without the usual headaches.
Firstbase One bundles the full suite into a single package for founders who want everything in one place.
Founders launching a US business, international entrepreneurs looking to incorporate in the US, and early-stage startups that want to get their legal and financial infrastructure set up properly without piecing together multiple services. If you're serious about building a company and want the admin handled from the start, Firstbase is one of the most complete solutions available.
