The company
HH&S is an IT systems and network consulting company founded in Paris in November 1992 by Henri Henault and his two sons, Eric and Stéphane.
What sets us apart is our broad-based IT and telecommunications background. We all began our careers in the IBM mainframe world and followed the evolution of computing through minicomputers and personal computers. This wide-ranging experience across different IT environments gives us deep technical expertise in designing information system architectures.
Our technical culture, expertise, responsiveness, service quality and the performance of our solutions have earned us recognition from the IT departments of major organisations. Our work spans consulting, development, migration, technical support, systems and network administration, and training.
As a strongly technical organisation, we also act as an external research and development partner for our clients. Our continuous investigation, assessment and troubleshooting of emerging solutions give us a broad view of today’s IT landscape. This work enables us to recommend and design efficient, sustainable and cost-effective technical architectures while helping clients avoid common pitfalls.
Our compact structure allows us to be highly responsive and agile. We have built a reputation for speed and effectiveness among both major organisations and SMEs. Clients also value our team’s ability to explain complex subjects clearly, drawing on our work and training to find technical answers, ideas and practical recommendations.
Our reputation has also grown through the close-knit IBM Mainframe community, our clients’ professional networks and word-of-mouth recommendations. We have become well known among major organisations in the French document production and output management sector.
This reputation, which we are proud of and committed to maintaining, has created opportunities abroad (Switzerland, Belgium, Luxembourg, Spain, Poland, the People’s Republic of China, Indonesia, Senegal and São Tomé). On several occasions, we have successfully delivered projects in extremely challenging conditions, with major technical, political and financial implications.
