Protime Register

The Swiss commercial register, right inside your AI assistant

Companies, registered persons, bankruptcies and calls to creditors — from the Swiss Official Gazette of Commerce. You talk to the commercial register in a chat; every answer carries the publication date and a reference to the source.

See for yourself

Results open in our company directory, which is in German. Company names and register entries appear exactly as officially published.

Free, no sign-up: one company, its publications back to 2002, each with the official PDF.

What Zefix does not show — and your AI chat alone cannot do

History, not a snapshot

Zefix shows today's register state. Here you see what changed and when — entries, exits, seat moves, capital changes, back to 2002.

Deleted companies too

Once a company drops out of the register, Zefix stops showing it. Here its publications remain, the deletion included — with the date and the official PDF.

Across companies

In which companies does a person hold a role? Who else signs for this company? Questions that run across the register — beyond the reach of a chat with web search.

Complete, not googled

An AI chat finds articles and snippets on the web, but never the complete list. Here it counts the official journal: every bankruptcy opening in a canton, every new registration in a sector — with filing deadlines.

Building publications too

Alongside the commercial register we read the cantonal building publications: who is building where, with the developer and the objection deadline. Currently 13 cantons — AR, BE, BL, BS, NW, OW, SH, SO, SZ, TI, VS, ZG, ZH.

Sourced, not asserted

Without register access, a language model will occasionally invent people or dates. Here every answer carries the publication number and the official PDF.

What a conversation looks like

Invented companies and people — the structure matches a real answer: event, date, signing authority, source.

Is Muster Bau AG in Bern still active, and who signs for it?

The company is registered and not in liquidation. Based on the publications, two signatories are active.

EventDateSigning authority

Does any of them hold roles in other companies?

The name A. Musterlin returns seven published events — they belong to two different people. The place of origin separates them cleanly.

What can you ask the chat?

Register questions — and combinations with what your assistant can do anyway: web search, comparing, summarising.

Is Muster Bau AG still active — and who signs there?

All bankruptcy openings in the canton of Berne in the last 30 days, with filing deadlines.

In which companies does A. Musterlin hold a role — and where did he leave?

Who joined or left Beispiel Immobilien AG since 2020?

What changed at CHE-102.674.664 since January?

Which new construction companies were founded this month?

This quarter's biggest capital increases — who is behind them?

What we do not promise

Bankruptcies only from September 2018

Commercial-register events — new registrations, mutations, deletions — reach back to 2002, some 156,000 publications in 2002 alone. Bankruptcies and calls to creditors only from September 2018: the predecessor archive carried the register rubrics only. Everything is updated daily; we keep extending the archive towards 1980.

Not an official register extract

The information is taken verbatim from the official publications and is not enriched from other sources. Only the register entry is authoritative; obtain an official extract before legally significant decisions.

Building applications from 13 cantons only

Building publications are available for AR, BE, BL, BS, NW, OW, SH, SO, SZ, TI, VS, ZG and ZH. The remaining cantons do not publish their building applications in a form that can be read daily — you will find nothing there, even where an application is pending.

No balance sheets, no debt-collection extract

Swiss companies generally do not publish their annual accounts, and a debt-collection register extract comes from the Betreibungsamt against proof of legitimate interest. Neither appears in the official gazette — so neither appears here.

No credit scoring

We assign no scores and no traffic lights. You see the published events and form your own judgement.

Purpose-bound

Access serves to check your own existing or prospective business relationships and to meet your own due-diligence obligations. Combining personal data into profiles is prohibited.
