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.

Formatting, exhibit differences and boilerplate may create false positives. This radar is not legal advice, a disclosure completeness opinion or a transaction recommendation.

Specific public-record cues, separated from generic language

Reads selected SEC filing text by sentence. Contents-page labels, generic risk language and allocation discussion are excluded; historical financing language is kept separate.

Scope: automated text screening of selected SEC filings only. Each cue requires review of the linked filing; it does not confirm a claim, legal status, tax status, financing completion or current issuer condition.

LEGACY TERM SCREEN · SOURCE INDEX

Financing, legal and disclosure cues

This screen counts source documents with a reading cue, never the number of underlying events. A cue may be generic risk language; open the cited SEC source before drawing any conclusion.

View screened SEC sources (4)
F-1/A · 2026-09-17F-1/A · 2026-07-22F-1/A · 2026-05-29F-1/A · 2026-05-21

Coverage boundary: this is a keyword screen of selected SEC filings only. It is not a court-docket search, tax-compliance review, lien clearance, sanctions screen, adverse-media search or a complete count of financings. A zero result means no matching term in the readable documents screened—not that the underlying issue is absent. Verify each cue in the linked official filing and use the appropriate independent professionals.

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.
