The campus hosts over 80 organizations, including major industry players such as Boeing, Northrop Grumman, and Accenture Federal Services, employing approximately 18,000 individuals.

Port San Antonio offers a range of facilities, including an industrial airport (Kelly Field), railport, foreign-trade zone, and residential areas. It provides services such as construction management, property management, maintenance, permitting, and logistics support. The Port is also home to the Boeing Center at Tech Port, a venue for events like MRO Americas, and is planning a new office tower to accommodate its growing tenant base.
