About Us
Contego Systems is owned by parent company Group One, LLC. Based in Newark, NJ, Group One is a holding company branched into seven different operating groups, with a diverse array of affiliated companies employing hundreds throughout the United States.

The company has grown from a single $600 per week contract to nearly $35 million in revenues. During its momentous growth, Group One has never lost sight of its founding goals and values, and we pride ourselves on holding to the highest standards.

Despite the vast array of industries Group One operates within, its focus remains singular: on establishing companies that provide the best value and most innovative solutions, no matter what the service.

Separation from the competition: One of the strengths of Contego Systems that allows us to operate more efficiently and provide a better value to our clients is the diverse operations of Group One and the resulting ability to have a lower cost basis. Many of our businesses offer supportive services to each other at cost, meaning we do not need to pay the same market prices our competition must pay to accomplish the same goals.

Among others, Contego Systems uses software and technology services from our I.T. services company, G1 Tek; gets its fleet graphics from our sign company, G1 Graphics; has its truck and equipment maintenance managed by our Computerized Maintenance Management Software (CMMS) offered by our facility maintenance company, G1 Facility Services. These are all keys to a better value for our customers.
