Start with an inquiry

If something is troubling you,
send it to us first.

It is hard to know from outside whether a matter belongs with an investigator, the police or a lawyer. Describe the situation and we will review it and tell you where it should go.

  • An inquiry is not a contract

    We listen and explain what is possible. You decide whether to proceed after you have heard the explanation.

  • We say so when we cannot take a matter

    We do not accept work that would require unlawful methods. We explain why, and whether another route exists.

  • Your inquiry is used for consultation only

    The information you provide is used only for consultation and deleted without delay when the consultation ends.

What we handle

Matters people bring to us.

Your situation does not need to fit a category. Tell us what happened in your own words.

01

Family & missing persons

Lost contact with family, a runaway child or teenager, or a missing person. We explain what can be done alongside a police report. For adults, we first confirm what the person's own wishes and Korean law allow.

02

Fraud & investment losses

We organize how the money moved and when. Contracts, transfer records and messages you already hold are reviewed together with a certified public accountant to clarify the loss and the key issues.

03

Counterparty checks before a deal

Before you sign or invest, we confirm that a Korean counterparty exists and actually operates, based on public registries, disclosures and on-site verification of the business premises.

04

Assets & fund flows

Stolen, lost or concealed assets, and fund flows connected to money you are owed. We tell you first what can be established from public records and the material you hold.

05

Personal & relationship concerns

When a spouse or someone close is the source of concern, we help you decide on facts rather than suspicion. We separate what can lawfully be confirmed from what cannot, and coordinate with your lawyer where litigation is involved.

06

Company matters

Suspected embezzlement, removal of company data or improper dealings with suppliers. Detailed analysis of books, bank records and electronic records is handled by THE PROFIT Financial & Digital Forensics Center.

Corporate investigations & forensics ↗

Cross-border matters

For overseas law firms, companies and investigators who need facts established in Korea. As a full member of an Asian professional investigators' federation (아시아공인탐정연맹), we first review what local law allows.

Bug & hidden-camera sweeps In preparation

Inspection of offices and homes for eavesdropping or hidden-camera devices is a service in preparation. Leave an inquiry and we will tell you when and how it will be offered.

Why THE PROFIT

Field investigation,
with forensics and accounting added.

What is confirmed in the field is checked against books, bank records and electronic records. Gaps that one method alone would miss become visible.

  • 01

    Seoul Gangnam Branch of the association

    THE PROFIT operates as the Seoul Gangnam Branch of the Korean Public Detectives Association (한국공인탐정협회). Chairman & CEO Joong-yong Jeong serves as the association's Vice President and Head of the Seoul Gangnam Branch.

    The association is a private-sector professional body. Korea has no state licensing system for private investigators.
  • 02

    Forensic techniques for firmer findings

    Mr. Jeong is an Associate Member of the Association of Certified Fraud Examiners (ACFE) and brings more than 15 years of accounting-firm experience and forensic technology to investigative work.

    ACFE associate membership and the Certified Fraud Examiner (CFE) credential are distinct.
  • 03

    Accounting and tax issues, reviewed directly

    Most matters involve money. Loss calculation, fund flows, and the asset and tax issues around a case are reviewed by a certified public accountant.

  • 04

    Named specialists

    Our Research Director and advisors include former police and National Intelligence Service professionals, a digital-forensics PhD and administrative agents, involved according to the nature of each matter.

How we work

From inquiry to report,
in a clear order.

  1. Inquiry

    Tell us the situation and what you need to establish, by phone, email or the form below.

  2. Feasibility review

    We separate what can lawfully be confirmed in Korea from what cannot.

  3. Written agreement

    Scope, timetable and fees are agreed in writing before work begins.

  4. Fact-finding

    Public records, on-site verification and analysis of the material you hold.

  5. Report

    Confirmed findings are reported separately from matters that could not be confirmed.

What we do not do

We stay inside
the limits of Korean law.

A private investigator in Korea is not a law-enforcement agency and has no investigative authority. Methods are limited by, among others, the Personal Information Protection Act, the Location Information Act, the Protection of Communications Secrets Act and the Attorney-at-Law Act.

This protects you as well. A client who commissions an unlawful investigation may also face liability. That is why we confirm the lawful scope at the inquiry stage.

  • GPS trackers, phone or account hacking, wiretapping
  • Unlawful access to communication, financial or personal records
  • Covert entry into homes or business premises
  • Repeated approach or surveillance that causes fear
  • Debt collection, threats or pressure
  • Guaranteed outcomes

FAQ

Before you engage us.

Is private investigation legal in Korea?

Yes. Since the amended Credit Information Use and Protection Act took effect on 5 August 2020, businesses may operate under the title "탐정" (detective). Investigators have no law-enforcement authority, and methods must stay within Korean law on personal information, location data, communications secrecy and the practice of law.

Can you work with our lawyers or investigators overseas?

Yes. We define the brief with the instructing firm: the facts to establish, relevant locations, timetable, and reporting language. Where proceedings are pending or planned, the scope is agreed with counsel.

How are fees set?

Fees depend on the facts to be established, the time required, the location and the people involved. Scope, timetable and fees are agreed in writing before work begins.

Can findings be used in court?

We report facts and records that were lawfully confirmed. Whether they are admitted as evidence is decided by the court or the investigating authority.
