Knowdys was born out of the development of GwethMarshall Consulting (GMC), the first economic intelligence and public affairs consultancy firm specialising in countries of the Central African Economic and Monetary Community (CEMAC). GMC was founded in France in November 2007 by Guy Gweth with the primary goal of contributing, on a practical basis, to the competitiveness of economic actors in Africa who are faced with the increasing international competition.
The creation of Knowdys LLC, Knowdys France SAS and Knowdys Cameroun SARL meets the growing need of enterprises and investors to be accompanied on the African continent (market survey, due diligence and screening of local partners), their installation (paperwork and installation support), and their growth (quest for new markets, intercultural risk management, competitive intelligence services).

To boost the competitiveness of its clients, Knowdys created a unique database on markets, main enterprises, and Sub-Saharan African leaders in 2007. Created some six years ago, and updated on a daily basis with information provided by primary and secondary researches, commercial databases, and internally-conducted decryptions, this tool is useful in generating high value reports in 10 key sectors : food industry, insurances, aeronautics industry, auto industry, energy, banks, construction and civil engineering, pharmaceutical industry, telecommunications, and minerals industry.

The Top Management of Knowdys Group is a member of SCIP (Strategic and Competitive Intelligence Professionals).
