History

 
Founded more than thirty years ago Bernard Huvé
 

1979 - SII was formed in 1979 in Paris by Bernard Huvé, the current chairman of its Supervisory Board.

1984 - An office was opened in Nice in connection with a project for IBM.

1987 to 1989 - In an effort to get closer to its clients, the Company opens two branch offices in the greater Paris region, at Cergy in 1987 and Vélizy in 1989.

1992 - SII is one of the first IT engineering and consulting company to receive an ISO 9001 certification for all of its operations.

1997 - Opening of an office at the Atalante technology park in Rennes, Brittany, for the telecommunications and digital television sectors.

1998 - Opening of a branch office in Aix-en-Provence.

1999 - IPO by SII on the “second market”, now Compartment C of the NyseEuronext Paris stock exchange.

2000 to 2003 - Expansion of the nationwide network with the opening of branches in Nantes, Toulouse, Strasbourg and Lille. SII decides to initiate a process improvement based on the CMMi®.

2005 to 2007 - SII’s foreign expansion begins with the opening of subsidiaries in Poland, Belgium and the Czech Republic. In France, the company’s regional branches add offices to increase their local presence.

2008 - Business grows in a sustained manner in France while the first foreign acquisitions accelerate SII’s international expansion :

  • SII Morocco is formed as an off-shore entity
  • Acquisition of Switzerland’s Coris Group
  • Acquisition of the Concatel Group in Spain

2009- An economic recession causes worldwide turmoil. Although SII is affected by it, the Group's structure enables it to continue operating steadily for the duration of the crisis.

2010/2011 - Demand picks up again in early 2010, and international expansion resumes :

  • Acquisition of AIDA Development in Germany
  • Opening of a subsidiary in Chile to bolster SII’s market position in South America

2011 to 2013- Despite the return of difficult economic conditions and a sharp slowdown in business investment, SII is adapting and preparing for the future. Internationally, the Group is still growing and conquering new markets; it made two acquisitions in 2011-2012 (Uniway in Belgium and Oevo in Lyon, France) and created a subsidiary in Bangalore, India in January 2013.


2013 to 2015- The gap widens between French and foreign operations
There has been a continued economic slowdown and decline in business investment in France. Revenue at SII fell for two consecutive years for the first time in the company’s history.

The offsetting growth in international operations has proved durable and validates the Group’s expansion strategy:
• New acquisition in Germany, amalgamated into existing operations,
• New subsidiary in the Netherlands,
• Acquisition in Colombia,
• Start-up of a business in Canada.

Today - SII operates from 54 locations in France and throughout the world.
