26M+ filings/transcripts indexed is wild, but the “validates every number” part is what I’m curious about — like are they doing source-linked citations down to the table cell, or some separate reconciliation step before it ever hits the model. Feels like the difference between “looks right in a demo” and something you’d actually trust in finance.
Yeah the phrase “validates every number” is doing a lot of work there — I’ve seen teams mean anything from “we show a citation link” to “we run a deterministic extraction + checksum/recalc step and the model only narrates the result. ” If it’s not cell-level provenance (table cell → parsed value → normalization rules → final number) with a reconciliation pass, I wouldn’t treat it as finance-grade, just demo-grade.
