WHAT THIS AUTOMATES

One evidence index instead of a manual filing hunt.

It groups recent reporting, registration/offer, ownership and governance filings, preserves the SEC source link and keeps a reusable chronology in the issuer’s record.

PROFESSIONAL DELIVERY LAYER

What teams can pay to automate next.

Cross-version text comparison, monitored alerts, change-specific diligence questions, CSV/PDF exports and a shared deal-team brief are the professional workflow built on this public evidence layer.

Only official SEC submission-index facts are automated here. The brief does not determine shell status, beneficial ownership, capitalization, legal compliance, valuation, active-trading status or transaction suitability. Those questions require the appropriate source documents and independently retained professionals.
