Private Investigator for Investigations Across Switzerland

Discreet Inquiries

Surveillance

Discreet observation helps to verify suspicions and document relevant facts effectively. Every operation is individually planned and conducted only after reviewing the legal requirements.

Legitimate Tracing & Searches

Tracing Missing Persons and Relatives

I assist you in locating missing or sought-after individuals and clarifying family origins, such as searching for a biological father, a biological mother or other relatives.



Before work begins, your identity, legitimate interest and legal standing are thoroughly evaluated. The privacy of the sought person is respected. Any contact or sharing of personal details occurs strictly within legally permissible boundaries.

Objective Verification

Infidelity and Theft

Where infidelity or theft is suspected, I provide support through discreet research and targeted investigations. The goal is to objectively evaluate suspicions and supply clear findings to guide your next steps.

Structured Investigations

Fraud Investigations

I support private individuals and corporate clients facing suspected deception, fraud or other unlawful actions.



Available information is systematically analyzed, cross-referenced and documented. The specific strategy depends on the details of the case and available legal options.

Documenting Incidents Clearly

Harassment and Threats

Repeated harassment, threats or stalking situations cause severe distress for those affected. I help you log and document relevant incidents and background information systematically.



In cases of immediate danger, contact the police straight away.

Source-Based Research

OSINT Research and Candidate Vetting

Open Source Intelligence (OSINT) involves the systematic research and analysis of publicly available sources.

For employers, I verify publicly available and career-relevant information submitted by applicants. This can include employment history, public qualifications, corporate affiliations and other job-related details.

Research is conducted with a specific purpose, proportionally and in strict compliance with Swiss data protection law. Only information that is legally permissible and directly relevant to the role is considered.

Further OSINT applications include identity verification, fraud detection, company network analysis, online reputation checks, source-backed background research and cross-border inquiries.



The findings are cross-referenced, evaluated for plausibility and compiled into a straightforward summary.

Beyond Regional Borders

Active Switzerland-Wide with International Reach

FSI handles assignments across the whole of Switzerland. For cross-border matters, I draw upon an established national and international network. Consultations are conducted in German or French.
