Companies
The official company registers: name, number, status, legal form, address, activity and filings, including every US state.
National and state registers, and the global register of legal entities (LEI)
The world's company registers, the people who run and own those companies up to the ultimate beneficial owner, sanctions and watch lists, politically exposed persons, offshore leaks, the news and physical infrastructure, in one search.
Every fact shows the register, list or article it comes from.

What it holds, how one search finds it, and how every link is explained.
Mercurium links a company across the registers of every country it operates in, the global register of legal entities, its websites and its LinkedIn pages.

Officers and directors, owners, the companies it owns, its executives, and the companies named with it in the news. A solid line is a link in the records, a dashed line a match by name only.

Sanctions designations, export controls, procurement debarments and regulator warnings from countries around the world, with who listed them and when. Politically exposed persons (PEPs) come with their career, their family and their associates.

Articles from around the world, read every 15 minutes, translated into English and linked to the companies and people they name.

Mines, oil and gas fields, platforms, pipelines, subsea cables and data centres, each tied to the company that runs or holds it. Ships and aircraft, with sanctioned vessels and their owners.


Every country's companies, officers and owners, what can be found there, and the laws that apply, article by article. Company registers from 280+ jurisdictions, including every US state.



Every kind of data a check needs, joined around the companies and people it describes. New sources are added all the time.
