Burlington, MA April 29, 2008 -- The Boston Business Journal (BBJ) named S4 Inc. as this region's 3rd fastest-growing private company in its second annual Pacesetters awards. This honor recognizes S4's skill in managing a rapidly growing company, showing robust revenues and creating business strategies that led to success in a competitive business environment. This is S4's second year making the Pacesetters List, ranking #14 on the 2007 list.

The Pacesetters list was determined by survey information gathered and analyzed by the BBJ from private companies throughout the Greater Boston region. Based on the information provided, 60 companies were selected on their revenue growth between 2004 and 2007, which had to exceed at least $1 million as of 2004.

"We are proud of our success and growth," said Chandu Shah, President and CEO of S4 Inc. "We want to be a company that's recognized for its qualities and the support we provide."

"This award acknowledges those private companies that skillfully navigate a competitive national and international marketplace and are growing quickly to be leaders in their field," said George Donnelly, editor of the Boston Business Journal.

These top-rated companies were honored at the Boston Business Journal's Pacesetters Awards breakfast on April 18th at the Sheraton Boston hotel. The 60 companies were counted down and their rankings revealed. Executives from these companies also shared their ideas on what made them successful and what they hope to achieve going forward.
