Switzerland-wide: Private Investigators for All Cantons

Our Zurich-based private and corporate investigation agency operates not only in the Canton of Zurich but across all of Switzerland, working with qualified, locally based investigators for private individuals, businesses, public authorities, and lawyers. We also conduct international investigations — for example in Liechtenstein — on behalf of clients from both near and far: +41 44 5522 264.

Regional Diversity Requires Local Knowledge

From around 4.07 million inhabitants in December 1930, Switzerland’s population grew to over 9 million by 2024, spread across 26 cantons. This diversity is reflected not least in the country’s multilingual character: German, French, Italian, and Romansh all testify to Switzerland’s rich cultural variety. In addition, regional dialects can pose a major communication challenge for visitors — but not for our Swiss investigators, who are well versed in local customs and speech.

 

With 210 inhabitants per km², Switzerland is not densely populated, and one might imagine it to be peaceful and tranquil. Yet, unfortunately, the Swiss motto “Unus pro omnibus, omnes pro uno” (“One for all, all for one”) is too seldom lived in practice. Many people act instead under the principle “All for me.” Such behaviour affects personal, corporate, administrative, and even criminal matters — all of which our Swiss private and corporate investigatorsare well equipped to handle on behalf of our clients.

Private Investigations | Private Detective Agency Switzerland

Many Swiss citizens face personal challenges that call for the discreet assistance of our experienced private investigators. Over the years, our detectives have handled countless sensitive personal cases with tact and professionalism — from suspected infidelity to stalking, custody disputes, and maintenance conflicts. These and many other issues form part of our agency’s daily work.

 

Our private investigation services in Switzerland also extend to criminal offences in the personal sphere, such as fraud, burglary, or vehicle theft. We are happy to help you resolve your issue — please use our contact form or call us directly.

Corporate Investigations | Corporate Detective Agency Switzerland

To reduce Switzerland to watches, Wilhelm Tell, the Matterhorn, and winter sports is to miss its true economic character. The Confederation’s main sectors are services (72%), industry, and agriculture. Switzerland’s most valuable brands — including Nestlé SA (Vaud), Credit Suisse AG, UBS Group AG, and Zurich Insurance Group (all based in Zurich) — underscore its global economic relevance.

 

Economic crime is particularly prevalent in major business hubs such as Zurich, Geneva, Basel, Bern, Lausanne, and Winterthur. Many companies, however, refrain from reporting every offence to avoid reputational damage. Whether in metropolitan or rural areas, our trained Swiss corporate investigators assist businesses swiftly and discreetly in cases of employee offences, corporate data theft, corruption, embezzlement, fraud, and other forms of economic misconduct.
