Gray Technologies, Inc. was established in 1992 by Mark Gray as a professional software engineering consulting and services company. From 1992 to 2000 Gray Technologies provided software engineering design and development services to 22 customers across 48 projects including the Department of Defense Maryland Procurement Office, Martin Marietta Laboratories, several Lockheed Martin divisions, and several other DoD prime and subcontractors. All projects focused on real-time embedded software design and development for digital signal processing (DSP) systems including radar, sonar, speech, and image processing systems on Analog Devices DSPs. During this period, Gray managed 11 employees and 10 subcontractors. Two significant projects that are deployed and operating today are the Arrow Continuation Experiments Ballistic Missile Defense Radar Seeker used by Israel in their airspace defense and the Light Airborne Multipurpose System (LAMPS) multi-mode radar on the U.S. Navy's SH-60B Seahawk helicopter used for U.S. maritime surveillance.

From 2000 to 2009 Gray moved from the defense market to the commercial market during the emergence and commercialization of embedded multimedia products utilizing audio and video encoders and decoders on Texas Instruments DSPs. During this period, Gray operated a Baltimore Maryland branch office for Ingeneint Technologies, Inc. with headquarters in the Chicago Illinois area and managed software engineering staff at an Ingenient branch office in Bangalore India as part of Ineneint's professional services business unit. Customers were worldwide primarily servicing the big commercial electronics manufacturers including GE, Hitachi, JVC, LG, Samsung, Sony, Toshiba, and many others. Drone technologies with video surveillance were under development during this period and Gray established and managed Ingenient's ITAR compliance requirements for U.S. customers in this space.

From 2009 through 2015, Gray was engaged as a founding partner of Nimbis Services, Inc. Nimbis provides low-risk, low-effort, pay-as-you go access to high performance computing (HPC) platforms and applications in the cloud for small and medium sized businesses and start-ups in the engineering and manufacturing supply chain who are unable to move beyond technical computing on the desktop. Small businesses and start-ups are critical players in the U.S. manufacturing supply chain. Because of barriers to HPC, these companies are often forced into slow and limited physical prototyping methods that do not have the advantages of modeling and simulation analysis provided by HPC. Gray’s function in Nimbis’ government sector was on the operational aspects of R&D projects with DARPA, DOE, and the U.S. Air Force. Gray’s function in the commercial sector was on testing, deployment, sales, and support of Nimbis' cloud products in the Nimbis marketplace.

From 2015 to present, Gray has contracted on U.S. Army intelligence systems at Aberdeen Proving Ground Maryland and more recently at Northrop Grumman in the BWI region in Space Systems on a space-based radar system for the U.S. Air Force and in Mission Systems on a mobile multifunctional radar system for the U.S. Marine Corps. With Gray Technologies’ 30 years of operation across highly diverse customers, systems, technologies, and ever evolving software development methodologies and tools, Gray has a proven track record of meeting the challenges and delivering results.
