C1S Group Named to the Inc. 5000 List of Fastest Growing Private Companies

For the fourth consecutive year, C1S Group, a full-service professional engineering and construction firm, has been recognized on the Inc. 5000 list of America's fastest growing private companies. C1S ranked #4101 on Inc. Magazine’s annual list of leading entrepreneurial businesses, and in the Engineering Category, it ranked 49th nationally. In all, nearly seven million companies were considered for inclusion on the list.


“Factors like material costs, increased competition, and the strength of the economy make the engineering and construction business extremely volatile. Few companies are able to experience the consistent growth we have enjoyed,” said Matt Strong, PE, LEED AP, and president of C1S Group. “I applaud our team for their ability to collaborate with our clients to determine the most creative and cost effective ways to solve their facility challenges. Our diverse group of professionals go above and beyond to deliver quality projects and that is why we have become a mainstay on this prestigious list.”

C1S experienced 67 percent revenue growth between 2013 and 2016, ranking in second place among engineering firms in Dallas and eighth compared to firms statewide. Compared to all Dallas companies on the list, C1S ranked 154th, and in Texas, the company ranked 351st overall in the group of fastest growing companies.

Inclusion on the Inc. 5000 list isn’t the only honor C1S has received from Inc. over the years. In 2016, C1S was named one of the “50 Best Places to Work” in the United States. This designation recognizes companies for building workplace cultures that allow their staff to grow along with the bottom line.
