The firm was founded in 1967 by Jean-Claude Coulon.
As a visionary of the future of the consulting profession, Jean-Claude Coulon was the President of the National Association of Legal Councils, and was responsible for the merger of the legal profession and legal counsel in 1990.
Jean-Claude Coulon was, in his own practice, hostile to all the artificial barriers, whether they were, the hyper-specialization of lawyers in a particular branch of law, or even the separation of law and economics, for advice must always be global in order to be coherent.
If Jean-Claude Coulon disappeared prematurely in 1991, his ideas and methods continue to influence the organization of the firm.
