Protime Register

The Swiss commercial register, right inside your AI assistant

Companies, corporate officers, bankruptcies and officially published debt-enforcement notices — from the Swiss Official Gazette of Commerce and the cantonal gazettes. You ask in plain sentences who is behind a company; the answer carries the publication date and a reference to the source.

What you can do here that Zefix cannot

History, not a snapshot

Zefix shows today’s register state. Here you see what changed and when — appointments, departures, relocations, capital changes, each with its publication date.

Across companies

Which mandates does an officer hold? Who else signs for this company? Questions that run across the register instead of one company at a time.

In conversation, not in a form

You don’t fill in a search mask; you write what you want to know. Following up is part of the conversation — and every answer names the official source.

What a conversation looks like

Invented companies and people — the structure matches a real answer: event, date, signing authority, source, and an explicit note on what the publications cannot prove.

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, three signatories are active.

Event	Date	Signing authority
New entry	14.03.2019	—
Board member appointed	02.07.2023	Sole signature
Managing director appointed	11.11.2024	Joint by two
Relocation within Bern	05.02.2026	—

No bankruptcy, no officially published debt-enforcement notice on record.

Does any of them hold further mandates?

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

Person	Company	Function	Status
A. Musterlin, of Thun	Muster Bau AG	Board member	active since 02.07.2023
A. Musterlin, of Thun	Beispiel Immobilien AG	Chair of the board	active since 19.09.2024
A. Musterlin, of Chur	Exempel Handels GmbH	Managing director	departed 30.04.2025

Whether this is the same person cannot be proven without the place of origin or date of birth. Two first-name variants are not merged automatically. Not an official register extract — only the register entry is authoritative.

Shall I list the other officers of Beispiel Immobilien AG? Five people are active there.

That the answer also states what it does not know is deliberate: a guess presented as fact does more damage than an open question.

Pricing

Two different jobs, two prices.

Set up your workplace

Register access belongs to the subscription, not the trial — the three free checks next to it apply regardless. Building guardian and AML guardian separately, CHF 39 a month each.

Further watchersA radar watches by itself and is included in the workplace. A guardian checks specifically what you name: building guardian for building publications with objection deadlines, AML guardian for PEP checks and an audit report.CHF 39 a month each

What we do not promise

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.

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.
