Located between Lake Constance and the Alps, the Canton of St. Gallen is one of the preferred operational areas of our investigators in Switzerland, as one of our senior case managers – together with his investigative team – lives directly on the cantonal border in Appenzell Innerrhoden. For private clients, companies, municipalities and lawyers, our detective agency in St. Gallen is the competent point of contact when it comes to proving marital or relationship infidelity, resolving custody disputes, clarifying maintenance issues, conducting missing-person searches, verifying benefit recipients, establishing cohabitation, investigating sick-leave fraud, expense fraud, bribery, and many other matters: +41 44 5522 264.
The city of St. Gallen, with its 83,617 inhabitants (2024), has been home to the Swiss Federal Administrative Court since 2012 and is, in several respects, one of the most important cities in the country. Tourists, however, are less attracted by its judicial institutions than by the historical buildings, mainly located in the Abbey District, a UNESCO World Heritage Site. National train connections – including routes to Chur, Zurich and Geneva – support domestic tourism but also serve trade and manufacturing. In 2023, the canton welcomed 560,000 guests, with nearly one million overnight stays. Among holidaymakers and business travellers, our investigators in St. Gallen occasionally encounter subjects of enquiry – for example, when clarifying doubts regarding a partner’s fidelity or when documenting employee sick-leave fraud.
Our detective agency works for local companies as well as for businesses based elsewhere, for residents of Switzerland and for international clients. We will gladly take on your case. Please contact us by phone or via our contact form.
Industry, trade and services are the dominant economic sectors in St. Gallen. Of the canton’s 535,114 inhabitants, approximately 320,000 pay AHV contributions, and the unemployment rate is an impressively low 1.9% (2024). Banks, insurance companies, the textile industry and the service sector – including tourism – contribute significantly to the gross domestic product, which amounted to CHF 44.5 billion in 2022. The secondary and tertiary sectors employed 35.1% of the workforce each in 2016.
However, economic strength inevitably attracts crime: warehouse and transport offences, unfair competition, burglary and data theft are only a few of the 25,888 reported infractions (18,574 under the Criminal Code) that companies had to deal with in 2015. Property offences accounted for 66.8% of all reported crimes that year, with particularly concerning numbers in burglary and sexual offences.
There were 393 burglaries into commercial premises, workshops and shops, and 867 into houses or rental flats. The clearance rate stands at a meagre 15%. Our experienced security specialists and corporate investigators in St. Gallen assist you in reviewing and optimising your protection measures, as well as in clarifying incidents after a loss has occurred – within the canton, across Switzerland and internationally: kontakt@kurtz-detektei-schweiz.ch.
The figures for sexual offences show an alarming trend: 32% of these offences involve sexual acts against children. The true number of unreported cases is undoubtedly much higher. Even worse, the clearance rate is a mere 18%. Do not hesitate to contact our private investigators for St. Gallen if you are confronted with such a case or any other sensitive matter. Our team is highly experienced with delicate private investigations and handles them with utmost discretion and care. You may contact us by email at kontakt@kurtz-detektei-schweiz.ch with a brief description of the case and your contact details, and we will get back to you promptly. Naturally, you can also reach us by telephone at +41 44 5522 264.

The Abbey District of the cantonal capital, featuring the Abbey Church of St. Gallus and Otmar, is the main attraction of the Canton of St. Gallen and therefore an important draw for tourism — and thus equally significant for the regional economy.
