The thesis

Most providers tell you the current state of a public company. Financials, ratios, ownership, ratings. That's a snapshot.

HawkData tells you the sequence. Every CEO change, insider purchase, buyback authorization, auditor switch, and material agreement — pulled from SEC filings, normalized into structured events, and stitched into a per-company audit trail.

Then we look across thousands of historical audit trails to estimate the probability of what comes next.

Step 1 — Extract

15 event types, all from SEC filings.

Each event is attributed to a specific form and item, normalized into a typed payload, and linked back to the source filing on EDGAR.

Step 2 — Organize

Every company gets an audit trail.

A chronological record of the major decisions and changes inside a public company — leadership, ownership, capital structure, governance — in one consistent schema.

    { "type": "ownership_disclosure",   "filed_at": "2025-11-02", "form": "SC 13D", "activist": true }
  ]
}

Step 3 — Predict

A probability layer on top of public-company history.

HawkData's prediction engine analyzes audit trails across thousands of public companies to identify the event patterns that precede important outcomes. Rather than predict stock prices, HawkData predicts corporate outcomes: acquisitions, bankruptcies, leadership turnover, activist campaigns, dividend moves, buybacks.

12%

Companies that exhibited CEO replacement → insider buying → share repurchase acquired within 24 months.

18%

Companies that exhibited Auditor change → executive turnover → debt restructuring entered bankruptcy proceedings.

22%

Companies that exhibited Specific governance + capital-allocation sequence initiated a dividend increase.

Illustrative figures. Actual probabilities are estimated per company from its specific audit trail.
