Evidence, discretion and cross-border reach.
Not every investigation requires the same approach. A suspicious insurance claim in Brno, a corporate fraud matter in Frankfurt, a child custody dispute in Prague, and a due diligence review on a Balkan beneficial owner each demand different skills, different legal frameworks, and different field teams. What unites them is the need for evidence that is collected lawfully, documented meticulously, and delivered in a form that decision-makers can act on immediately.
Exero Group is a licensed Czech private detective agency operating under the Czech Trade Licensing Office with registration IČO 09022104. Our investigators are licensed under Czech law, which means the evidence we produce is admissible in Czech civil and criminal courts, and our procedures are proportionality-tested before any surveillance or field operation begins. This matters: an inadmissible file is worthless, no matter how dramatic the footage.
We work in English and Czech as standard, and our caseload is delivered exclusively within the European Union, Czech Republic, Germany, Austria, Slovakia, Poland, Hungary and beyond, under EU law and GDPR. Every engagement is led personally by a senior investigator who owns the file from intake to final report. We do not outsource casework to third parties, and we do not take on matters we are not equipped to deliver to our own standard.
Licensed & Court-Ready
All evidence is collected under Czech licensing law with documented chain of custody, proportionality assessments and full GDPR compliance. Reports are structured for direct use in civil litigation, criminal referral or insurance settlement.
Bilingual & EU-Wide
Native-level English and Czech with operational experience across the entire European Union. We understand local EU legal cultures, coordinate multi-jurisdiction teams within the Union, and deliver findings that translate across EU borders without losing precision.
Senior-Led, End-to-End
The investigator who scopes your matter is the investigator who runs it. No hand-offs to junior staff, no outsourced field teams, no black-box subcontractors. Every file is owned by a named senior investigator from intake to final report.
Our approach
Evidence-led investigations, built to stand up in court and in the boardroom
For more than three decades we have helped law firms, insurers and corporations resolve sensitive matters in a way that holds up before a court, a regulator and an internal audit committee. Every engagement begins with a short intake assessment, what is the lawful basis, what outcome does the client actually need, and what risks does the inquiry itself carry, before any operative, OSINT tool or forensic analyst is deployed in the field. See the full breakdown on our services overview and worked examples in our case studies.
In the Czech Republic we operate under a private-investigator concession (Trade Licensing Act, Annex 3) and run every assignment on a GDPR-first footing. For each file we maintain a record of processing activities, document the proportionality balancing test, and archive evidence with verified timestamps. Our investigators are prepared to give oral testimony in Czech and EU courts and to support the written report with cross-examination, which is often decisive in civil proceedings. We summarised the legal framework in our whitepaper on the legality of private investigations.
We work bilingually in Czech and English and routinely coordinate cross-border operations across the European Union. For multinational clients, a single point of contact in Prague means a unified quality standard across jurisdictions: the same evidence-collection protocols, the same data retention rules, the same reporting cadence. Common questions are answered in our FAQ; client feedback lives on the testimonials page. Ready to start? Get in touch.
Sectors and process
Sectors we understand and how an engagement with us begins
Exero Group works extensively with insurers and reinsurers, where we verify the circumstances of claims, staged injuries, fraudulent vehicle theft reports and inflated indemnity demands. For law firms we build evidence packages for civil and commercial litigation, trace witnesses, serve process and run forensic analysis of digital footprints. Corporate clients rely on us for third-party due diligence, internal fraud investigations, intellectual property protection and technical surveillance counter-measures (TSCM bug sweeps) before sensitive negotiations.
Our roster also includes private equity and M&A advisors who need Enhanced Due Diligence on counterparties under EU AML, KYC and sanctions regimes, as well as family offices and high-net-worth individuals for whom we handle sensitive personal matters, asset protection and pre-employment screening of key hires. We regularly partner with the compliance teams of multinational corporations on internal investigations into white-collar crime, conflicts of interest and code-of-conduct breaches.
Every engagement begins with a free initial consultation, usually within 24 hours of first contact. After an NDA and engagement letter are signed, we deliver a written operational plan with budget, milestones and a clear definition of success. You receive regular interim updates throughout the inquiry and, at the end, a structured report in Czech or English with annexes, photo documentation and metadata, ready to submit to a court or regulator. All evidence is held in encrypted storage for the period defined in our retention policy and then irreversibly destroyed. To discuss a matter discreetly, write to hello@exerogroup.cz or call +420 737 335 352.
