Welcome to Thailand Private Investigations (PI)

We are a group of private investigators and analysts, offering a wide range of prices and services, from small jobs to considerable assignments. Most of us are Thais with diverse skills and experience at all levels of society, which is important to be effective in Thailand and cost efficient. Alternatively, we offer western expat private investigators with extensive experience in mainstream Thai culture as well as the tourist areas and business regions.

Our main office is in Bangkok but we cover most of Thailand. (Pattaya and Phuket operations are common.)

The two Directors of our company are a husband and wife team -- American and Thai -- Mark and Kanta ("Na"). Our staff are mainly researchers and surveillance agents to watch and follow people. Mark and Na are not just desk directors, they are often in the field.

We are sensitive that our work in many cases will affect peoples lives quite significantly -- both the customer's and the subject's -- so we are careful to do the right thing, and diligent to do our best. We carefully choose which cases are acceptable (no overly selfish or ill intent). We discreetly protect your identity. Key traits of our private investigators are understanding, nonjudgemental, minimal bias, objectivity and positive attitude. We understand a wide variety of people (both Thai and foreign) and their origins, options in life, and outlooks, all without arrogantly judging. We find out facts for you to base your decisions. We usually don't judge for you, and are willing to offer extensive analysis and advice, based on the 10+ years of operations in Thailand of our investigation operation.

Thus, we basically find out "The Truth" and more facts, and offer analysis based on an intimate understanding of Thailand and broad, in-depth experience, without pre-judging or prejudice, using an appropriate team from our diverse private investigators.

The kinds of private investigator assignments we accept include:

  • Discreet investigation of a Thai girlfriend (note some case studies there)

  • Discreet investigation of a foreign husband in Thailand

  • Discreet investigation of a known Thai girlfriend of husband, son, or friend

  • People Finder or Missing Person

We steer away from the really bad stuff that goes on in this world. Others can deal with it; not us. Of course, as regards possibly causing trouble and making trouble for yourself it's better to not take risks, no matter what side you're on or which viewpoint you take. Nevertheless, our refusals are not an overreaction on our part. The reason we refuse those realms is simple and basic: It's just bad karma to get involved with in any way. What goes around comes around. It doesn't matter who you know or what you know, bad karma is bad karma, and good karma is good karma.

We are not shady sleuths, and this is not Hollywood nor fantasy spy novel stuff. We are longtime professionals operating systematically, for ordinary private citizens to find out personal information for only their own purposes, and for businesspeople to help their business in ethical ways.

We want to emphasize that we are usually not "out to get" anybody. Counseling is often part of this business. For example, for wayward husbands, we try to keep families together, especially if children are involved. A cheating husband will deny everything until shown proof. You cannot start to solve a problem if it's in denial. Better to resolve it sooner than later, before it gets too far along. People make mistakes. (See our Mating 101 viewpoint.)

Scamming girlfriends are another matter altogether, but there are also cases in which the results of field work aren't so black and white, and need considerable analysis, too, such as understanding situations more openly based on information collected.

Some of our investigators have been thru similar experiences in our more foolish years. Live and learn. Just like we don't want to repeat our foolish mistakes, we can also help other people from making mistakes. Thailand's permissive and freewheeling environment can carry people away at times.

On the other hand, many times there are innocent partners whereby there are misunderstandings, lack of information, and other considerations. Peace of mind can be worth a good night's sleep and more productive days.

We can see the good side of people. (Money scammers aside.) Even when there are conflicts of interest which require hard decisions, we try to do what is right overall and advise likewise, for the greater good. We try to reason with all people, for everybody to keep their cool and maintain reason over emotion.

Our policy is safety first for everyone, whether it be situations of potentially violent emotions, undercover work, or in traffic during surveillance.

We are not officials of any government. We are private investigators, performing this service commercially. In P.I., the P = Private, not Public. "Private eye" is OK, but "detective" technically means detecting crime which we do not do (though we do "detect" cheating girlfriends/wives and husbands).

Indeed, compared to expecting much for free from government employees in any country (including embassies, consulates, and local indigenous officials), it is often more appropriate to contact a private sector entity, which in many kinds of cases will be more responsive, can be directed more flexibly, and will be willing to provide superior quality of service. (Private agents are successful because they seek challenges, diversity, and adventure, not security and repetition in a government bureaucracy. We are also independent, not needing to take orders from any government bosses -- we often don't agree with our governments! We accept the cases we want to do, and reject those we don't. We earn our keep and our reputation.)

If you need dynamic, talented, and resourceful entities on the ground in Thailand, intimately familiar with the Thai language (especially written), the Thai culture and the various systems here, then it would be difficult to find anyone better than us. Our core people are highly educated Thais, some of us well travelled, and maintain close relationships with good expat associates on call.

We accept both small and fairly large investigations.

In cases requiring an opinion: Objectivity and broad experience are important. Individuals' viewpoints can be biased by attitude, limited realm experience, conformity with one's peer group, analytic deficiency, and other factors. A team of talented and experienced investigators is essential for accurate overall perceptions, insights, and analysis.

You will usually deal with one of these three managers (surnames withheld from Google as regards PI work!):

Ms. [name withheld here], (Thai), was formerly a journalist. She has countless contacts in investigative journalism and all levels of Thai society.

Mr. Mark [surname withheld here], from Washington, D.C., is the expat communications consultant who helps with day-to-day native English communications. Mark is a well known entity in Thailand via his website , a guide to working and living in Thailand (and includes a popular subsection on Thai girlfriends). (Surname on that website.) Living in Thailand continuously since 1994, Mark makes no secret that he has usually "been there, done that" and experienced the same feelings and events as many customers. Mark also has a personal website at mark[surname].com

Mr. Peter [surname withheld here], from Scotland, originally was a lawyer but became involved in military intelligence, then got an MBA and moved back into the private sector to perform corporate investigations. He has lived in Asia since 1992, travelling around working mostly on proactive due diligence projects, as well as performing and directing advanced corporate investigations. Peter also runs and travels around the Asia region a lot. (Surname on that website.)

The rest of our in-house people are all Thai, for performing research, analysis, surveillance & undercover (for Thai girlfriend and foreign husband investigations), and various kinds of field work.

We also have longterm relationships with Thai and expat associates located in popular areas and/or who are in useful positions or specially skilled and experienced.

However, we do not outsource unless it is beyond our capabilities. It's easy to simply outsource and take a cut, but that cuts quality assurance, too. Our staff are trained and improved, we have standard operating procedures (SOP), and things are double checked. We don't make excuses to avoid work or justify shortfalls in results. We know who is reliable, and SOP includes double checking things.

Being a detective or private investigator is not a job many people can do well. Effectiveness starts with having the right kinds of people -- who can analyze, see hints and opportunities, come up with creative solutions, have the self-confidence and social smoothness to implement those solutions, and perseverance. Quality also comes from proper training, standard operating procedures, and of course experience! Teamwork is essential.

We work from the same office building as a well known Thai-English translation company (see also ) located on a different floor, though the private investigation agents are entirely separate and most of them are deployed in the field most of the time. (If you call either company, then ask for Ms. Kanta or Mark to transfer the line to us.)

We employ Thai agents fulltime, plus we have many parttime agents in particular places and with special experiences and skills, including the Bangkok tourist areas, Pattaya, Phuket, and several other places around Thailand.

"Agents" (as opposed to "assets") are trained and undergo an "apprenticeship" before performing on their own. Above, we are talking only about "agents". If you want to count "assets" and "contacts", we have vast resources.

Regarding highly serious business cases: When we should, we work closely with contacts -- experts in a particular field. This is especially true in the case of attorneys, as the field of law has many specializations and lawyers have different circles of contacts. If investigation of a case could significantly benefit from bringing in directly experienced associates of any kind, then we do so. Greedily trying to do everything oneself can result in poor, inaccurate and irresponsible reporting, especially by non-Thais in Thailand.

Thus, some jobs require carefully putting together a team.

However, many of our jobs are small assignments on a budget (e.g., info and people finders), whereby one Thai agent can perform all the research electronically, on the phone and/or in the field.

For example, people finder missions are usually given to our female investigators, because they are better welcomed than a man (especially if searching for a lady! -- imagine the different reactions), and the female investigator is also more understanding and gets far more trust and information in the community.

Only under certain circumstances do we send out an expat, because expats stand out in Thai society (i.e., not discreet), cannot read/write the language they are surrounded in, and usually can speak the language only as far as ordinary street talk goes. Imagine sending a Thai into foreign society to perform a private investigation...

It is worth noting that many foreign entities fly in an expat private investigator (someone they know closely) for assignments in Thailand. This is often a mistake. (However, it's a fun Thailand assignment for them!) The cost is much higher and the results are usually mediocre at best ... and can be counterproductive. An effective investigator should:

  • be intimately familiar with the territory
  • be fluent in the language -- written and spoken at all levels
  • have all the cultural nonverbal mannerisms, ingrained, with mainstream Thai society (not just dodgy subcultures)
  • be discreet
  • have the necessary contacts in their trusted inner community

Often, when a person needing help in Thailand chooses to use a friend, associate, crony or other sources to do the work, the results are not nearly as good as using a skilled private investigator. Professional agents are skilled, reliable and can be directed systematically in ways that other assets cannot.

Just any ordinary Thais won't do, either. Thailand is a class oriented society (whereby most people from Western cultures don't "get" many of the subtle cues in the social and professional dynamics), and the effectiveness of an investigator depends upon their class and walk of life. Our investigators include the entire range of classes, and are of diverse walks of life. Some are effective at getting information; others are best at blending in or befriending a particular subject's associates.

In any case, it is important to employ the right person for the job, not necessarily someone who just happens to be available, such as your friend or someone who just needs work and money. For good results and discretion, hire a professional.
