What problem does it solve? Finding out who actually owns or controls a company is hard because corporate disclosure varies enormously by jurisdiction, registries publish different data under different access models, and nominees, trusts, and layered structures are designed to obscure the real owners. This Skill provides the tradecraft to navigate official registries, filings, and offshore leak datasets to trace ownership and control. ## Core Features & Use Cases - Registry navigation: Covers OpenCorporates, UK Companies House and the PSC register, SEC EDGAR, US Secretary of State registries, EU business registers, GLEIF LEI records, OpenOwnership, OpenSanctions, and the ICIJ Offshore Leaks database, with a per-registry catalogue of access models and identifier formats. - Officer and address pivots: Searches a director's other appointments across registries using normalised names and birth month/year anchors, and evaluates mass registered-agent addresses by overlap rather than raw count. - Filing timeline analysis: Reads filing histories chronologically to detect change-of-control events, nominee directors, dormant-to-active shelf companies, and insolvency patterns. - Use Case: A compliance analyst needs to verify the ultimate beneficial owner of a UK supplier for KYB screening. The Skill walks through pulling the Companies House record, running the officer pivot across eleven appointments, screening names against OpenSanctions, and grading each finding as confirmed, probable, unconfirmed, or assessed. ## Quick Start Ask the agent to find out who really owns and controls a named company, including its directors, shareholders, and ultimate beneficial owners.
