“Will it go up?” is the wrong question.
Ask: do I want to own this business — and is the price fair?

6,057 US-listed companies, valued nightly by a deterministic, version-controlled engine, straight from their SEC filings. Every number shows its work: click a footnote, land in the actual 10-K.

i. What this is

Deterministic, not vibes

Same inputs, same answer, forever. Engine v0.1.0. Every methodology change is versioned and golden-tested. Ask an AI to improvise a DCF and you get a different number each time; ask this engine and you get an auditable one.

Numbers with receipts

Our data comes from the filings themselves, not a licensed black box, so revenue links to the XBRL tag in the 10-K it came from. Reading financial reports is a skill; this is the training ground.

Honest refusals

A cash-flow DCF is meaningless for a bank. Where a model doesn’t apply, the ledger says not applicable and explains why. No confident wrong numbers.
