Public filings, read properly.
Everything below is built from documents anyone can download, and none of it requires an account. The work is not the access — EDGAR is free and has been for thirty years — it is turning six documents into one situation, noticing what moved between them, and being able to point at the sentence that says so.

Eleven things, 7 of them finished
Marked live if it reads the graph today. Marked planned if the ingestion and storage behind it already exist and only the surface is missing — which is the honest distinction, and a more useful one than a roadmap.
Special situations radar
liveEvery live merger, tender offer, exchange offer, going-private transaction, spin-off and activist campaign the graph knows about, with current terms and the filing that set them.
SC TO-T · SC 14D9 · SC 13E3 · 8-K · DEFM14A
Tender offer tracker
livePrice, expiry, withdrawal rights, minimum condition, proration and board recommendation — and the spread against a price you supply.
SC TO-T · SC TO-I · SC 14D9
Corporate action calendar
liveExpiries, withdrawal cut-offs, election dates and record dates in one list. An extension supersedes the date it replaced rather than sitting beside it.
Tender and exchange offer documents
Activist and 13D radar
liveWho crossed 5%, at what percentage, and whether Item 4 states an intent to engage rather than a passive holding.
SC 13D · SC 13G and amendments
Insider activity
liveOpen-market purchases and sales only, by default. Grants, option exercises and shares withheld for tax are most of Form 4 volume and almost never the thing anyone means.
Forms 3, 4 and 5
Company directory
liveEvery listed filer in the SEC universe — ticker, exchange, CIK and CUSIP — each with its own event timeline. Roughly eight thousand companies, ten thousand listings.

Company event timeline

Filing diff
plannedWhat changed between two filings — risk factors added, going-concern language removed, a termination fee modified. The extraction pipeline already stores sectioned text and fingerprints for exactly this.

Merger spread calculator
plannedGross and annualised spread, proration and downside, against a price you enter. EDGAR publishes no quotes, so the price is always yours and the assumptions are always shown.
Situation terms
Four questions, and only the last one is scarce
Plenty of products answer the first question. A few answer the second. Almost none finish the fourth, which is where an operations team currently spends its week.
What just happened?
Primary filings, read as they are disseminated. A tender offer is not six documents — it is one situation with a price, an expiry, a set of conditions and a chain of amendments, and that is how it is stored.
Does it touch anything I hold?
Watch a deal, a company, an activist or a query. The agent has a job description rather than a subscription: tell me if the offer price moves, if a second bidder appears, if the shareholder vote is rescheduled, if a new 5% holder crosses in.
What are the options, and what do they pay?
Terms, economics and deadlines against the filing that set them. Spreads are computed against a price you supply, never an invented one, and the assumptions are printed next to the answer.
Who does what, by when?
Position matching, the election, the approval, the instruction to the broker or custodian, the acknowledgement, and the reconciliation of what actually settled. This is the half that no intelligence product does and every operations team does by hand.
Does this help us own the lifecycle of a securities event?
A tool that feeds the event graph earns its place. A tool that is merely a nice thing to have on a finance website does not, however easy it would be to build.
- A Form 4 trackerIt feeds the event graph, and it is a search entry point.
- A 13D radarActivism is a situation, and situations are the wedge.
- A tender trackerIt is the wedge, rendered publicly.
- An enterprise election agentIt is the lifecycle.
- A generic P/E screenerNothing about it touches an event.
- A crypto news feedDifferent market, different workflow, no contribution to the graph.
- An AI stock pickerInforming a decision is the product; making one is not.
Derived from public SEC EDGAR filings. Extraction from prose is heuristic and carries a confidence; every figure links to the document it was read from. Not investment, legal or tax advice.
