Know any company in minutes — a complete, sourced file built from the public record.
Website & widget · npm package · VS Code extension · Methodology
Company Dossier compiles a complete, source-attributed intelligence file on any business — entirely from public data — and lays it out so you can read the whole company in minutes instead of weeks of open tabs. Every dossier is organized into nine sections, and every claim is tied back to its source:
Overview & identity · People & org chart · Hiring radar · Money trail · Locations · Tech fingerprint · News & timeline · Relationship web · Risk flags
Public sources only. Free.

npx company-dossier acme.com # writes a "<Company> DOSSIER/" folder + dossier.json
npm i -g company-dossier # or install globallyimport { buildDossier } from 'company-dossier';
const { json, files } = await buildDossier('acme.com');An MCP server ships in the box (company-dossier-mcp / company-dossier-mcp-http, tool
build_dossier) so ChatGPT, Claude, and other agents can generate dossiers too.
Most OSINT tools dump raw data. Company Dossier produces a structured,
source-attributed, confidence-tagged intelligence file — readable in minutes,
built only from public sources. See methodology/OVERVIEW.md
for the full breakdown, validated results (613 structured files on a real company),
and the 7-phase pipeline.
