Before Felix touched anyone else's money, it had to survive ours. The founder runs a freight brokerage — real Bank of America statements, wire transfers, fuel, contractor payments, and the messy Zelle-and-Cash-App reality of an owner-operator account.
Felix rebuilt those books from the raw statements, and the regression is re-run by hand whenever the ingest or tax rails change (the statements are private and never leave the founder's machine, so it is not part of the automated suite): 3,348 transactions across 14 statements from 2023 to 2026, every statement reconciling to $0.00, about 82% auto-booked and the rest flagged for review instead of guessed.
Every figure traces back to its ledger entry (the §0.1 law: a deterministic ledger does the math, the AI only labels) — and you can verify a Felix export yourself, offline, in your browser.
