Private Investigator Amsterdam
A licensed local investigator you can trust from anywhere
When you need certainty about something in Amsterdam, a partner, a business contact, a person, an address or a fraud, you need more than an amateur with a camera. SAJ Recherche is a private investigation agency licensed by the Dutch Ministry of Justice (POB 8779), based in Amsterdam. We carry out discreet, lawful fieldwork on the ground and report to you in clear English, whether you are an expat here or watching from abroad. Either we confirm what you suspect, or we let you put the doubt to rest, with evidence that stands up.
What a licensed private investigator in Amsterdam can do for you
Surveillance & discreet observation
Our investigators follow and document a subject's real movements in Amsterdam and the wider Randstad: where they go, how long they stay and who they meet, logged with times, locations and, where possible, photographic evidence.
Partner & infidelity investigation
Discreet confirmation of what is really going on when you suspect a partner. A frequent request from clients abroad whose partner lives, works or travels in Amsterdam. See our dedicated infidelity investigation page for the full approach.
Fraud & financial investigation
Corporate fraud, invoice and investment fraud, hidden assets, conflicts of interest. We map the facts objectively and report in a form your lawyer can use.
Background checks & due diligence
Pre-employment screening, integrity checks and due diligence on individuals or companies before you hire, partner or invest, within strict Dutch privacy law.
Digital & open-source (OSINT) investigation
We examine public sources, social media and digital traces that confirm or contradict an account. We never hack devices or use unlawful tracking, only evidence that holds up.
TSCM bug sweeps
Suspect a hidden camera or microphone in a hotel room, office or boardroom? Our technical surveillance countermeasures team detects covert devices and secures the finding properly.
Stop guessing. Get the facts.
A free, confidential consultation, wherever you are in the world.
