Board memberships and roles

Public registers only provide role lookups by company, not by person. Open a company associated with the person and see “Board and other roles”, or use Brønnøysund role lookup using the company organization number.

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the person page

Name and birth year reduce ambiguity but are not necessarily a unique identifier. Do not merge people without supporting links.

Follow company links for registered ownership interests and onward to roles, accounts and grants.

Search the name for alternative birth years or spellings.

Distinguish between ownership, role and historical affiliation; one relation does not prove another.
