Tieout

SEC filings → sourced data

Every number,
tied to its
source.

Type a ticker. Tieout reads the SEC’s XBRL data, builds the three statements, and marks every figure with where it came from — the exact tag, the filing that reported it, and for anything computed, the arithmetic behind it.

US filers with XBRL data.

A figure the filer never reported comes back blank, never as zero. A zero would flow through every calculation downstream and produce a confident, wrong answer.

Apple’s FY2025 10-K, as extracted. Every figure carries a mark; every mark opens onto its source.

Read the marks

Auditors tick and tie.

When an auditor agrees a figure to its source, they mark it and print a legend explaining what each mark means. Tieout uses the same convention, so you can read provenance off the page without clicking anything.

What gets checked

Seven identities, run on every extraction.

A check that cannot run says so. Banks have no cost of revenue, so the gross profit cross-foot reports not applicable rather than passing — a check that quietly passes when it never ran is worse than no check at all.

Three modes

Extraction is live. The rest is being built.

Extraction

Working now

Statements, derived metrics, segments, and growth rates — each figure marked with its source and checked against seven accounting identities.

Analysis

Next

Revenue drivers, margin bridges in basis points, working capital swings, capital allocation, unusual items. Every number computed in Python before a word is written about it, so the prose cannot invent a figure.

Modelling

Planned

Three-statement model, DCF, LBO, and comps as live Excel formulas — driver cells in blue, a checks tab, and the circular interest reference handled the way a banker would expect.

Start with a filing you already know.

Check the numbers against the 10-K yourself. That is the only way a tool like this earns its place in your workflow.
