Alexandre Ribeiro : A Life Dedicated to Private Investigation
Private investigation is not just my job; it's my legacy. I grew up observing the mastery of my father, one of the pioneers of private investigation in Portugal , at a time when the digital world didn't exist and the success of a case depended exclusively on shrewdness, patience, and newspaper footnotes in advertisements.
It was in this environment of discretion and rigor that I honed my instincts. I began my journey in 2001 , at just 16 years old, learning the art of surveillance and intelligence gathering "the old-fashioned way" —where precision was the only rule.
The Journey of a Specialist
At 24, with the experience of someone who had already spent almost a decade in the field, I decided to found my own agency . Since then, I have led highly complex investigations in Portugal and abroad , adapting my inherited instinct to the most advanced technologies of the 21st century.
Today, I have over two decades of uninterrupted experience , guaranteeing my clients a rare combination in today's market: the wisdom of the old guard with the technical efficiency of the modern era.
Credibility and International Recognition
My clients' trust is underpinned by my absolute commitment to ethics and legality. I am Partner No. 33 of LIDEPPE ( League of Professional Private Detectives of Portugal ), one of the oldest and most respected institutions in the sector .
Through LIDEPPE, I am also an integral member of the IKD ( Internationale Kommission der Detektiv-Verbände ), the prestigious International Federation of Private Detective Associations . This international recognition allows me to operate with a global network of contacts, guaranteeing support in cross-border investigations with the highest quality standards.
In a crucial strategic step towards our internationalization and prestige, we are proud to announce that we are now members of the WAD ( World Association of Detectives ), the oldest and most prestigious association of private investigators in the world. This integration places us at an elite level, providing access to leading global resources and partnerships.
Further reinforcing our commitment to excellence and representation in the sector, we have also joined APDPE ( Professional Association of Private Detectives of Spain ) under membership number 1326.
This partnership expands our operational capacity and the exchange of specialized knowledge, consolidating our strategic position in the Iberian market and continuously raising the standards of rigor and professionalism that we apply to each investigation.

As investigative specialists, discretion is our fundamental principle. We neither intend nor should we appear on television; we prioritize anonymity to preserve the effectiveness of our field operations—which is where we are truly useful and important to our clients.
However, our technical expertise makes us a benchmark in the sector. This often leads us to be a source of information for national television channels, as happened in this TVI report, which cites data and experience from the company Detetives Privados Portugal.
Trust is built on results and confidentiality , not on exposure.
Real results and guaranteed satisfaction with complete professional confidentiality.
