SEC private placement research

Move from individual notices to reproducible observations. Compare filing activity, separate original notices from amendments, and inspect differences between issuer disclosures. Every result uses records stored in Form D Explorer.

Monthly filing activity

A twelve-month history of notices, amendments and distinct CIKs, plus a comparison of two completed calendar months.

Amendments and disclosure coverage

See how much of the dataset consists of amendments and how often numeric fields are usable before building an analysis.

Compare states or industries

Apply the same dates and definitions to two categories. Inspect issuer counts, amendment shares and each category's share of stored submissions.

Filing change viewer

Choose two filings for the same CIK and compare reported amounts and investor counts, with source links and missing-value safeguards.

Research notes from real disclosures

Fixed editions with explicit periods, source checks and downloadable calculation snapshots. Live tools can change as records are imported or corrected.
