Private investigator in Amsterdam

A licensed Dutch private investigation agency for international and local clients. Discreet surveillance, fraud, partner and background investigations, English-speaking and legally admissible.

  • Ministry of Justice licensed (POB 8779)
  • English-speaking & remote intake
  • Evidence that holds up in court

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.

Built for clients who need someone local and discreet

Our clients are expats in Amsterdam, internationals abroad, and companies and lawyers, all needing the same thing: a licensed, discreet investigator who reports clearly in English.

You live abroad

You need eyes on the ground in Amsterdam

You are in the US, the UK, the Gulf or elsewhere and need something verified in Amsterdam, a partner, a business contact, a person or an address. We act locally and report to you in English, wherever you are.

Expat in Amsterdam

You live here, but the system is foreign

Navigating a Dutch investigation in a second language is daunting. We work entirely in English, understand the expat reality, and handle everything discreetly and lawfully.

Business & legal

You need evidence that stands up

Companies and lawyers engage us for fraud, integrity and due-diligence matters where the report has to survive scrutiny in a Dutch or foreign proceeding.
