A private investigator in Mexico who finds the people, money, and truth others can’t.
Locating missing people, tracing assets, exposing fraud, and vetting who you’re dealing with — discreet, licensed fieldwork for families, attorneys, insurers, and corporations. On the ground, nationwide. Investigador privado en México.
A missing person, a trial date, a surveillance window? Flag it as time-sensitive at intake and we prioritize your case.
Credentialed specialists with real field experience across Mexico.
GrayCat PI is a private investigation firm registered in Mexico (SAS) and the United States (Corp), working in all 32 Mexican states. There is no single “private investigator” license in Mexico — so each of our investigators is a credentialed specialist who holds a Cédula Profesional from the SEP in their own field and is registered with the tax authority (SAT).
Cases are coordinated by a licensed case manager (SEP No. 14357746) and worked in English, Spanish, French, and Arabic — for families who need answers and for attorneys, insurers, and corporations who need evidence that holds up.
Two kinds of clients. The same standard of discretion.
Most people who reach out are families in a difficult moment. The rest are professionals who need evidence that holds up. We’re built for both.
A loved one you can’t reach. A truth you need to know.
We handle sensitive personal cases with care, in plain language, in English or Spanish.

How much does a private investigator in Mexico cost?
Most investigations start around $1,000 USD. After a private review we quote your exact case — a fixed scope and price before any work begins, never an open-ended retainer. What moves the number: how urgent it is, how many states are involved, and how much fieldwork it takes.
Are your investigators licensed in Mexico?
Mexico doesn’t issue a single “private investigator” license. Each of our investigators is a credentialed specialist who holds a Cédula Profesional from the SEP — in fields such as law, criminology, criminal justice, accounting, or forensic science — and is registered with the tax authority (SAT), issuing official CFDI invoices. Cases are coordinated by a licensed case manager, SEP No. 14357746.
Will my case stay confidential?
Always. Inquiries are reviewed privately by a licensed investigator, and the subject of an investigation is never notified.
Can you find a missing person in Mexico?
Yes. Missing persons and welfare checks are our most-requested service, worked on the ground by resident agents in the region involved.
Can you locate someone in Mexico from the United States?
Yes — most of our locate cases start from the U.S. We work from whatever you have (a name, an old address, a CURP, a phone number) to find missing relatives, witnesses, biological family, or someone who’s gone quiet, and confirm it on the ground.
Do you work with attorneys and insurance companies?
Yes. We handle litigation support, witness location, service of process, claimant surveillance, and due diligence — documented to legal standard.
Can you verify a property or developer before I buy?
Yes. Real-estate and pre-construction fraud is one of the most common cases we see, especially in resort areas. We confirm title, ownership, permits, and whether a developer and its representatives are who they claim to be — before your money moves.
How long does an investigation take?
Most cases move to fieldwork within 48 hours of intake. Urgent matters — missing persons, court dates — are prioritized immediately.
What languages do you work in?
English, Spanish, French, and Arabic, across all 32 Mexican states.
Do you cover my city or state?
We operate in all 32 states, with resident agents concentrated in the highest-activity regions. Ask about availability for any location.
