Firstbase.io is a Delaware LLC formation service for non-US residents, starting at 399 USD with a first-year total cost of ownership around 699–899 USD (including state franchise tax), and ongoing annual costs of ~499–699 USD. Compared to Stripe Atlas (500 USD starting), it offers lower pricing and more bank flexibility. Compared to Doola (197 USD starting), it has stronger brand backing but is slightly more expensive. Best suited for non-US solo developers who need a US business entity but do not require immediate Stripe payment integration. Key considerations: 4–8 week EIN wait, tax filing must be arranged separately, and the 300 USD annual Delaware franchise tax is not included.
