Reviewers mostly describe Firstbase.io as unreliable and support-heavy in the worst way: long delays, weak communication, generic ticket replies, and missed or unclear compliance steps after incorporation. Several say they had to chase basic updates, re-enter information, or deal with upsells and changed service expectations, while refund handling and eligibility limits left some feeling trapped. A few users report smooth, fast LLC formation, but that is the clear minority. Overall, the reviews suggest uneven execution, especially once filings, tax paperwork, or edge cases appear.
