【Lida International Investigation Agency · Why We Started】

Almost everyone who walks through our door is carrying a question they find hard to put into words.
Lida International Investigation Agency was founded in 2007, born from a simple idea: in an age where truth is hard to tell from fiction and people are hard to read, everyone deserves a lawful, reliable, and trustworthy way to confront the truth that matters most to them. When we started, there was no shortage of firms willing to take on a case — but few treated "lawful" and "transparent" as non-negotiable principles.

Lida set out to redefine what a private investigation firm should be, through proper investigative methods, clear pricing, and genuine empathy for each client's situation. That founding purpose remains unchanged to this day.

Whether a case succeeds or fails comes down to how sound the reasoning is and how solid the evidence stands. Lida's investigators don't work alone — they operate as a cross-disciplinary team: seasoned investigators handle case planning, on-site evidence gathering, and intelligence analysis; legal consultants review the legality and evidentiary value of every step; and technical specialists use professional equipment to close information gaps. We believe truly reliable investigation work comes from combining human intelligence with technology — so that every piece of evidence can withstand scrutiny.

Founder — Hsieh Chih-Po

Lida International Investigation Agency is led by its founder, Mr.Hsieh Chih-Po. Having devoted many years to the investigation industry, he has been committed to advancing its professionalism and transparency, and is the author of Zhai'er Holmes' Odd Jobs Agency. Under his vision, Lida aims to be more than just an ordinary investigation agency — by leading through example, he hopes to raise the professional standard and public perception of the entire industry, so that the words "private investigator" carry the weight of trust and professionalism they deserve.

【Lida's Promise to Every Client】

Behind this promise is Lida's rigorous quality assurance system. From case assessment and contract signing, through execution, to final delivery, every stage follows clear standard operating procedures overseen by dedicated staff. Throughout the investigation, a project management and progress-reporting system keeps clients informed every step of the way, while internal reviews ensure our methods stay lawful, the evidence is complete, and every report is accurate. We believe true peace of mind doesn't come from a verbal promise — it comes from a system that can be examined, and that never cuts corners.
