Firstbase.io
Incorporation and compliance platform built for international founders launching US companies
About Firstbase.io
Firstbase.io is a global-first incorporation platform that helps non-US founders form a Delaware C-Corp or LLC, get an EIN, set up a US business bank account, and stay compliant year-round. It bundles formation, registered agent, mail forwarding, and post-incorporation services (tax, bookkeeping, legal templates) under one dashboard designed for startups and remote founders.
Pros & Cons
Pros
- Widely trusted by YC-backed and international startup founders for Delaware C-Corp formation
- Strong post-incorporation ecosystem (banking, legal docs, tax) designed for venture-backed companies
- Clean dashboard built specifically for remote, non-US founders
- Includes 83(b) filing assistance — critical for startups issuing founder stock
Cons
- More expensive than budget formation services like Bizee or ZenBusiness
- C-Corp emphasis means LLC-only founders may find cheaper specialists
- Bookkeeping and tax are paid add-ons, not bundled like doola's Total Compliance
