Our Services
Professional investigation services across four specialisms.
Corporate
View all →For employers and directors with a concrete suspicion: fraud, theft, sick leave that does not add up, breach of a non-compete clause or misconduct. We establish the facts in a way that holds up in employment proceedings or with the police. Beforehand we assess whether the investigation is proportionate and stays within the GDPR.
Individuals
View all →For individuals with a personal question: doubts about a partner, a missing relative, stalking, fraud or address fraud. We work discreetly, from public space and with open sources, and record only what your question requires. The result is a factual report that you can also hand to a lawyer or the police.
Legal
View all →For lawyers and legal professionals who need evidence in a civil, employment or family law case. We gather facts, verify witnesses and opposing parties, conduct open-source research and record everything with source and date so the file can be used in proceedings. We work with Breedijk Advocaten and tailor the report to your case.
Real Estate
View all →For landlords, owners' associations, property managers and housing corporations who suspect a property is being used differently than agreed: subletting, sham occupancy, vacancy, cannabis cultivation or nuisance. We document the actual use and deliver a file you can use to negotiate, terminate or go to court.

How to choose the right investigation
Our range is broad. In practice it comes down to three questions.
Start with the question, not the service
What do you want to know or be able to prove at the end? That determines the type of investigation. Sometimes it is two, sometimes a conversation with a lawyer comes first. We discuss this at intake.
Know what is legally allowed
Not every question may be investigated. Investigating a person requires a legitimate interest and must be proportionate. Read what a licensed agency may and may not do.
Know what it costs
We work with an hourly rate and fixed prices for clearly defined services such as a TSCM inspection or a background check. See our rates page for indications per investigation.
