Registerbuch
Claude connectorCommunitySwiss commercial register for Claude: companies, signatories, auditors, bankruptcies and building notices — every answer linked to its offi…
Registerbuch connects Claude to the Swiss Official Gazette of Commerce (SHAB) and cantonal building notices, from 2002 to today. Ask who signs for a company, which audit firm checks its books, what a company published and when, which bankruptcies in a canton have open creditor deadlines, or check a whole list of companies at once. Every row links the signed official PDF on amtsblattportal.ch (or the ETH Library digitalisat for older years), so each answer can be checked in one click.
Registerbuch can also check a draft report or client mail claim by claim against the register, and it estimates company size where no figures are published, clearly marked as an estimate.
Not an official register extract. Information about persons is for business purposes only (e.g. checking signing authority); see registerbuch.ch/nutzungsbedingungen. A free quota is included; beyond it a Protime plan is required. By blueSky Information GmbH, Lucerne.
