Unfair Competition Investigator in France
When a competitor crosses the finish line
Competition is healthy as long as it remains fair. It becomes harmful when a former employee, partner, or competitor poaches your customers, lures away your staff, disparages your company, or exploits information that does not belong to them. These actions can cause lasting damage to your business, yet they are often carried out behind the scenes, making them difficult to prove.
To file a lawsuit for unfair competition, obtain a preliminary injunction, or claim damages, mere suspicion is not enough: you must prove your case. However, a victimized company rarely has the internal resources to document these facts in a manner that will be admissible in court. This is precisely the role of a licensed private investigator: to gather objective evidence that can be used in court.
The sooner you take action, the more you can limit the damage and the easier it is to document the facts. Our assistance allows you to respond in a systematic manner rather than in a rush, and to build a solid case that your attorney can effectively rely on.
What Our Survey Covers
Our investigation aims to uncover these unfair practices and identify those responsible:
Finding of Misappropriation of Customers or Suppliers
Identification of Organized Poaching of Employees
Identification of acts of disparagement or freeloading
Investigation into the misuse of files or know-how
Dated and documented findings that can be used in court.
Each item is time-stamped and documented in a clear report. When the facts involve the gathering of strategic information, the investigation naturally extends to our services in combatingindustrial espionage.
How is the investigation proceeding?
It all begins with a confidential, free, and no-obligation consultation, during which we analyze your situation and define a clear objective. We provide you with a plan of action and a detailed estimate. Our investigators then conduct fieldwork and, if necessary, use open-source information throughout France, with the utmost discretion. Upon completion, you’ll receive a detailed report, designed to be submitted as evidence in legal proceedings or used by your legal counsel.

Admissible evidence for taking action
The success of an unfair competition lawsuit depends entirely on the quality of the evidence. An investigative report prepared by an accredited firm—one that is factual and dated—provides the guarantees of legality expected by the judge, making it admissible against the opposing party. Conversely, evidence obtained through unfair means would be excluded from the proceedings and could weaken your position.
We therefore compile each case file with its legal purpose in mind: a precise description of the facts, the context, and no speculative interpretations. This rigor enables your attorney to base a request for injunctive relief, damages, or interim measures on indisputable grounds.
Act quickly to minimize the damage
In these cases, time is against the victimized company: every week of embezzlement represents a loss of revenue and an erosion of your market position. Launching an investigation quickly allows you to document the facts while they are still evident and, if necessary, obtain emergency measures to put a stop to them. We tailor our investigative procedures to meet this need for responsiveness.

Findings from the Field and Digital Sources
Unfair competition occurs both in person and online. This includes physically poaching customers, aggressive solicitation, as well as disparaging remarks on social media, unauthorized use of your brand, or copying your content: we combine on-the-ground monitoring with the analysis of open-source intelligence to cover the entire spectrum. This comprehensive approach ensures that no aspect of the misconduct is overlooked and provides the judge with a complete picture of the wrongful conduct.
We take care to date and contextualize each observation, because it is the accumulation of consistent evidence that is persuasive. An isolated fact is open to debate; a body of consistent findings, established over a period of time, provides much stronger evidence of misconduct and the resulting harm.
A Harm That Is Being Documented
Getting the conduct to stop is one thing; obtaining compensation is another, which requires demonstrating the extent of the harm. We therefore focus on documenting not only the acts themselves, but also their effects: identifiable loss of customers, a corresponding decline in business, and disruption. These elements provide your counsel with the basis to quantify the claim for damages on a tangible basis.
This thorough documentation often makes the difference between a symbolic award and compensation that truly reflects the actual damage suffered. We remain available to your attorney to clarify the findings throughout the proceedings, whether in a regular lawsuit or in summary proceedings.
Finally, we work with you with the discretion that this type of case requires: at no point should the investigation alert the competitor or disrupt your ongoing business relationships, as this could worsen the very situation you are seeking to resolve.
