Greystones Group named 2027 Elev8 GovCon Honoree for second consecutive year. WASHINGTON, D.C. - October 21, 2026 - Greystones Group, a woman-owned small business delivering innovative digital solutions to the U.S. military and federal civilian agencies, has been named a 2027 Elev8 GovCon Honoree for the second consecutive year. The Elev8 GovCon Award recognizes federal government contractors that exemplify #DoItTheRightWay through excellence in innovation, collaboration, talent development, community engagement, sustainability, and continuous improvement. The Federal GovCon sector continues to be one of the most complex and competitive marketplaces in the world and the consistent and long-term winners of today and tomorrow are those companies which understand they must not only bring to the table efficient and effective solutions, but also a corporate culture that demonstrates their own excellence, making them a beacon for talent, for partners, and for clients. The recognition caps a year of momentum for Greystones Group. The company was named a 2026 NVTC AI50 Honoree. Its Soleite Fleet Edge(TM) solution was designated "Awardable" on the Chief Digital and Artificial Intelligence Office's Tradewinds Solutions Marketplace. "Agencies are moving fast to field AI, and they need partners who can deliver it responsibly and keep the talent to sustain it," said Sheila Duffy, CEO of Greystones Group. "That's what Elev8 measures, and it's what our team has focused on this year, from getting Soleite Fleet Edge on Tradewinds to growing leaders from within. This recognition is theirs." Greystones leaders were recognized across the GovCon community this year. Duffy was named a DCA Live Rising Star of GovCon and a 2026 IGNITE honoree, and CTO John Mark Suhy was named to the Accelerate 125.

Greystones Group technical paper selected for presentation at the American Society of Naval Engineers Fleet Maintenance & Modernization Symposium 2026. WASHINGTON, D.C. - Sept. 16, 2026 - Greystones Group, a woman-owned small business delivering innovative digital solutions to the United States military and civilian federal government, today announced that its technical paper has been accepted for presentation at the American Society of Naval Engineers (ASNE) Fleet Maintenance & Modernization Symposium (FMMS) 2026. The paper describes a reference architecture for applying AI to maintenance processes, schedules, and technical data supporting distributed and unmanned maritime assets, including unmanned vessels (UVs). The paper is presented in general terms and does not describe any fielded system, program of record, or customer environment. It reflects Greystones' ongoing independent research investment in data-driven sustainment and readiness, an area in which the company applies proven AI and machine learning technologies to reduce operator cognitive load and enable better, faster decisions. "Sustainment is one of the areas where AI can make the most immediate difference, and FMMS is the right forum to work through how," said Sheila Duffy, CEO and Founder of Greystones Group. "As the fleet's reliance on unmanned vessels grows, so does the need for maintenance and readiness approaches built specifically for these platforms. We're proud to share our technical perspective with the naval engineering community and to contribute to the conversation on how technology can accelerate fleet readiness." FMMS 2026 will take place September 22-24, 2026, at the Virginia Beach Convention Center in Virginia Beach, Virginia, under the theme "From Foundry to Fleet: Delivering Readiness & Capability." The symposium brings together the U.S. Navy, U.S. Coast Guard, U.S. Marine Corps, Military Sealift Command, industry, academia, and the broader naval ship maintenance and modernization community for an open exchange of technical information on ship maintenance and modernization. The FMMS agenda features senior military keynotes, industry speakers, panels, an Innovation Theater, and technical paper presentations. The FMMS selection adds to a period of growing momentum for Greystones in naval maintenance and modernization. The company continues to invest in research and development of AI-enabled maintenance tracking and data analytics capabilities for distributed and unmanned maritime systems, and was selected earlier this year to present at the Naval Applications of Machine Learning (NAML) 2026 conference.
