# Corridome

> US private-markets data from SEC filings and firms' own websites. Who is raising a fund, who is selling a company, and which bank ran the deal, every fact with its source.

Corridome is based in New York. It reads Form ADV, Form D and 8-K exhibits, and the firms' own websites, and builds a database of PE advisers, broker-dealers, placement agents and the deals they worked. A sample of the database is open to everyone, and a free account opens every record. Members get full lists, the source documents, direct contacts, exports, alerts and the Corridome connector for Claude and ChatGPT. Team plans add seats and single sign-on. Corridome also builds private versions of the pipeline for one firm, owned by that firm.
