What you can ask for
Your assistant picks the right tools and fetches data live.
Find companies
Search Danish companies by name, CVR, industry or municipality — and look up industry and municipality codes.
Financials
Pull key figures and full financial history: revenue, profit, assets and equity.
Ownership & people
Look a person up and see which companies they own or run — including ownership networks and beneficial (indirect) ownership.
Properties
See which real estate a company owns, with address, type and area.
History
Follow a company over time: management, board, ownership, and name and status changes.
Risk & legal notices
Find Statstidende notices — bankruptcy, dissolution, restructuring — linked to a company.
Similar companies
Find competitors and comparable companies in the same industry and area.
Production units
Find physical business sites (P-units) — search by industry, municipality or geographic proximity.
Free and Pro
Search, company profiles, the latest financial year, similar companies and Statstidende notices are free. Pro unlocks full financial history, ownership and people lookups, properties, history and production units — and lifts your monthly limit significantly.
Your assistant tells you along the way if something needs Pro.
