Created in 2003, Deisk's unique purpose is « the knowledge of the information system ».

Spurred on by Jean-Hervé Laveau, former director of the development of Wincap Software and of Cyrano for the Wincap product (and then for the Soamai product), as well as a precursor of open language interpreters based on the Syntactic Interpretation Bases, Deisk has federated a team of engineers who specialize in the parsing of languages and meta-models of the information system.

Having pioneered the issues of « knowledge of a legacy system », code analysis, meta-modeling of heterogenic environments, and qualimetry, and gained the necessary experience, Jean-Hervé started up Deisk , a consulting firm specializing in a technology that focuses on the knowledge and quality indicators of the information system for study and production purposes.
