In Paris, businesses operate in a highly competitive environment where unfair practices are, unfortunately, common: customer poaching, data theft, industrial espionage, and even defamation.
In these situations, a private investigator becomes a valuable ally in protecting your company’s strategic interests. With the Aquila Group, our licensed investigators step in to gather evidence that is legally admissible and usable in Parisian courts.
Unfair Competition in Paris: How a Private Investigator Can Protect Your Business

What is an act of unfair competition?
Under French law, unfair competition refers to any abusive or unlawful practice that harms a competing business.
The most common forms in Paris include:
- the poaching of customers or employees,
- breach of non-compete clauses,
- the counterfeiting or unauthorized use of a trademark or concept,
- defamation on the Internet or social media,
- industrial espionage and the leakage of strategic information.
These actions are punishable by law, provided they can be proven in court —and that’s where the private investigator comes in.
The Role of a Private Investigator in Paris in a Case of Unfair Competition
A private detective, also known as a private investigator, operates strictly within the law to establish the facts.
Their duties include, in particular:
- identify the perpetrators of unfair practices;
- monitor suspicious commercial transactions or data transfers;
- document a violation of a non-compete clause;
- collect physical evidence (evidence, witness statements, seized items, reports).
In Paris, the Aquila Group’s investigative reports comply with the requirements of the Commercial Code and the Code of Civil Procedure, and may be submitted in court to support your legal actions.
