Exero Group gave us the regional knowledge and on-the-ground reach we couldn't get from a US firm." Sarah M. New York, U.S.A. Asset Tracing "We had an enforceable judgment and no way to collect. Exero Group located the debtor abroad, identified two operating companies he was tied to and gave our enforcement counsel exactly the evidentiary base they needed. The matter moved within weeks of receiving their dossier." Štěpán R. Prague, Czech Republic Asset Tracing Due Diligence & Background "Pre-acquisition EDD on a Central European target. Exero Group surfaced two undisclosed UBOs and a pending sanctions exposure that would have killed the deal post-close." Ondřej V. Prague, Czech Republic Enhanced Due Diligence "We needed deep OSINT on a counterparty in 48 hours. Exero Group delivered with full source citations, exactly what our compliance committee required." Lenka K. Prague, Czech Republic Data Intelligence (OSINT) "Cross-border EDD into a Czech-German joint venture. Exero spoke our compliance language and Czech registry detail in the same report. First-class." Klaus W. Munich, Germany Enhanced Due Diligence "Before signing a major partnership agreement I asked Exero Group to vet the counterparty's principals. They surfaced an undisclosed insolvency history within 72 hours and saved us from a very expensive mistake." Martin K. Prague, Czech Republic Background Checks "We were closing a Central European acquisition in a tight window and our usual EDD provider could not move fast enough. Exero Group turned around a fully sourced founder profile in under 48 hours, flagged a regulatory issue nobody else had found, and let us renegotiate before signing. Exactly the calibre of work I expect." Maximilian H. Hamburg, Germany Enhanced Due Diligence "Our internal team had hit a wall on a cross-border counterparty profile. Exero Group came in, worked in five languages, and produced a sourced dossier within three days that our risk committee could rely on. They are now a standing partner on our European matters." Laura B. Boston, U.S.A. Data Intelligence (OSINT) Private Clients "Discreet, professional and methodical. The team at Exero Group gave us evidence we could actually use in court with clean chain of custody, timestamped, irrefutable." Tomáš N. Prague, Czech Republic Surveillance Services "Operating outside Prague is rare for many agencies but Exero Group handled our Brno surveillance with the same precision and discretion we'd expect in the capital." Hana B. Brno, Czech Republic Surveillance Services "I first hired an unlicensed private detective in Prague for my child custody case and got completely burned. They claimed they could not get any evidence, no documentation of any kind, and a lot of money wasted. Exero Group took over, delivered the licensed, court-admissible evidence I needed, and my attorney was thrilled with the report. It cost less than what the unlicensed agency charged me for nothing." Veronika J. Prague, Czech Republic Matrimonial & Family Investigations "Our family had lost contact with a relative for over a decade. Exero Group located him in another country within two weeks and handled the first contact with extraordinary sensitivity. We're forever grateful." Eva T. Prague, Czech Republic Missing Persons "I needed evidence for a custody hearing but was terrified of doing something that wouldn't stand up in court. Exero Group explained the legal limits up front, ran a structured four-week observation under Czech procedural rules, and delivered a report my attorney filed without a single change. The hearing went our way." Kateřina P. Plzeň, Czech Republic Matrimonial & Family Investigations All testimonials are published with the explicit written consent of the client.
