Daniel Gelston has been appointed CEO of Constellis Holdings LLC, with outgoing CEO Terry Ryan transitioning to executive vice chairman and reporting to the board of directors as part of a planned leadership transition.
In his role, Gelston will lead efforts to integrate predictive analytics and AI-enabled operational insights into Constellis’ core service delivery, aiming to move the company from reactive security to a more proactive, technology-driven prevention model, the company said.
The board named Gelston as the next CEO after a global search, citing his enterprise leadership experience, defense and security background across military and private-sector roles and expertise in AI and data-driven solutions, according to Board Lead Director Michael Lundin.
“Together, these strengths align perfectly with our critical mission supporting government and private sector customers,” Lundin added. “His strategic leadership will accelerate Constellis’ transformation as we sharpen our focus to advance technology, data integrity, and leverage artificial intelligence to better serve customers and to anticipate evolving global challenges.”
Gelston launched and scaled the government business at C3 AI, securing major wins in AI-driven mission solutions across the Defense Department, intelligence community, federal law enforcement and civilian agencies as president of C3 Federal Systems. He later served as group president for defense and security and CEO of CAE USA Inc. His career also includes senior leadership roles at L3Harris Technologies, Smiths Detection and Cobham.
“I am honored to lead Constellis at this pivotal moment and grateful for the confidence the Board has placed in me,” Gelston said. “This organization stands at the forefront of adaptive technology to enhance security and safety for national and global organizations. We are committed to enabling customer success by accelerating informed decision making, embedding AI innovation, and delivering integrated solutions. I look forward to collaborating with our experienced personnel and valued customers to outpace emerging threats and unlock new opportunities for impact and growth.”
