Thailand's leading detective agency

Our detectives are experts at gathering intelligence and delivering it back to our clients in real time. We are practiced in covert surveillance and rely on techniques which are used by law enforcement agencies across the world. Most of our agents are former police or military personnel and well equipped with the skills to provide discreet surveillance. Bangkok is a unique place with a class system that is to be respected and navigated carefully; we have operatives and contacts from all walks of life which we rely on to complete investigations in Thailand. We have excellent contacts within most sectors of the government which helps us to provide document retrieval services.

Due to the prevalence of romance scams in Thailand, much of the work that we do is investigating Thai women for our clients. However, we also investigate an equal amount of foreign men that are visiting the country to indulge in the sex industry. We also provide due diligence for our corporate clients who are engaging in business with Thai companies, and everything in between. Whether you need to run a background check on an individual, surveil a property or retrieve a company's balance sheet, we can help. Get in touch with us and see what we can do for you.
