Document extraction from filings and register data, reconciled into a directed ownership graph
A directed ownership graph that shows who owns and controls European companies, from direct shareholders up to the ultimate parent.
Company-to-company ownership edges with percentage held and control type (shares, voting rights, management control), computed ultimate parents, and group membership for every entity. Where a beneficial-ownership register or filing lawfully discloses them, natural-person beneficial owners are included with name, nature of control and ownership band only. Each edge records its source document and validity dates, so you can reconstruct the structure as it stood on any past date.
Edges are extracted from shareholder lists, group structure notes in annual accounts, and register data, then reconciled into one graph keyed on Grundwerk IDs. Since the 2022 ruling of the Court of Justice of the EU on public access to beneficial-ownership registers, several EU registers restrict access; coverage of beneficial owners is therefore labelled per country, and we include those records only where access is public or granted for a legitimate interest. Corporate edges cover about 19 million companies; the graph is updated weekly.

from 3 reviews
We sent a messy export with duplicates in four languages. They returned registry IDs for most accounts, a duplicate cluster file and a short list of low-confidence matches to review by hand. Finished inside the quoted two weeks.
Anja F., CRM manager, Industrial software vendor
Beneficial-owner access differs a lot by country, and the ownership graph labels exactly where data is official, where it is derived from shareholder filings and where it is missing. That clarity mattered more to us than raw coverage. The API has been stable for eight months.
Pieter V., KYB product owner, Business banking fintech
We used to maintain separate scrapers and contracts for a dozen registers. Grundwerk gives us one schema with the original register reference on every record, which our auditors liked. Officer data is thinner for a few countries and the documentation says so upfront.
