Holding company of two specialist firms: a licensed private investigation agency and a privacy certification body for the hospitality industry. One organisation behind both.
SAJ Group B.V. was incorporated on 7 October 2026 as a holding company and holds the shares in SAJ Recherche B.V. and Privacy Shield Group B.V. Its registered seat is Amsterdam.
Both operating companies work under their own name and with their own clients. SAJ Recherche carries out investigations: private, corporate and technical. Privacy Shield Group audits and certifies how hotels handle the privacy of their guests.

Both companies have their own website with services, rates and contact options.
Investigation agency in Amsterdam, licensed by the Dutch Ministry of Justice and Security. Private and corporate investigations, counter-surveillance and evidence that holds up in court.
