The Founder 

Walid el Abed

Founder & CEO

Dr. Walid el Abed has more than 20 years of experience in working with global
organisations and is a recognised international lecturer, visiting professor at renowned French and Swiss universities, as well as the author of several scientific and economic articles including white papers that are in international circulation.

Guided by data and objectives

Dr. el Abed’s journey began in the 1990s when, as a student, he took a keen interest in the prospect of automating the dialogue between man and machine. This interest led him to study linguistics and computer science. In 1995, Dr el Abed created Data Excellence Science, a study that integrates computer science, linguistics, business management and AI to process natural language (semantics) and transform it into IT language (code).

Dr el Abed’s scientific discipline is the foundation of the AI platform DEMS (Data Excellence Management System). Today, Data Excellence Science is taught in several leading universities in France and Switzerland such as the University of Franche-Comté, the University of Fribourg and the Conservatoire National des Arts et Métiers de Paris.

A revolutionary technology

In recent years, DEMS has become an attractive proposition for organisations and is considered a revolutionary technology in data and AI governance. “Currently, Global Data Excellence (GDE) is funded by the European Commission and in a very short period of time organisations from both the public and private sectors have invested in us. A major driver of our success is the time to value production, which is currently unmatched in the industry,” explains Dr Walid el Abed.


Walid el Abed is surrounded by a team of experts in Marketing, Sales and Partnerships, Project management, IT and Technology who work together to provide you with the best service.

State of Valais

The case of Bacardi shows that DEF/DEMS provides a more complete picture of the data quality than traditional solutions, by putting information into its business context. It enables to focus preventive data quality efforts where the returns will be pertinent for the business, with a clear identification of the value at stake. This capability makes DEMS unique in the data and information governance ecosystem.»


« GDE is the only company that appears to understand that data governance rules must be linked to data requirements (templates) which must themselves be linked to a dictionary. Most (all) the other applications I have seen so far are truly insufficient for the purpose of effectively managing data governance at least as I and the ISO 8000 community understand it. »

ECCMA, Peter Benson

« From the outset, GDE has supported Groupe Mutuel in its data governance approach.
GDE offers a methodology and a tool perfectly adapted to this approach. Other approaches exist on the market. However, it seemed to us that GDE had a competitive advantage with its Data Excellence Framework and Data Excellence Management System products. This choice proved to be the right one.
In just under ten years, we have transformed GM’s data from a cost center to an asset that we can now leverage. »

Groupe Mutuel Assurances
