Commenting on Barbaccia’s first win, Executive Mosaic CEO and Wash100 Award founder Jim Garrettson said, “Gregory’s first Wash100 win comes at a pivotal moment, as he takes the helm as U.S. federal CIO under a new administration that’s prioritizing innovation, security, and modernization. With a decade at Palantir and additional leadership roles in other top-tier private sector companies, plus his background as a U.S. Army Intelligence veteran, Gregory is the perfect leader to tackle the complex challenges of federal IT. His expertise in cybersecurity and advanced analytics is exactly what the government needs right now, and we can’t wait to see how Gregory pushes federal technology forward in the year ahead.”
Gregory Barbaccia’s Career Highlights
The newly appointed federal CIO is a GovCon industry veteran who has over 15 years of leadership experience.
Before joining the federal government, Barbaccia served as chief information security officer at Theorem. In his two years as CISO, the executive developed and implemented the company’s information security strategy, which included managing cyber risks and incident response.
Before Theorem, he briefly led Elementus, a universal blockchain search engine and institutional-grade crypto forensic solution provider, as president. Under his leadership, Elementus supplied its compliance and data analytics technology to U.S. agencies in support of high-profile cyber investigations.
Barbaccia spent over 10 years at Palantir, where he assumed responsibilities of increasing importance. He served as head of intelligence and investigations and led programs related to counterintelligence, insider threats, open-source intelligence, and security and legal investigations.
The tech leader founded Argus Vigilance, a firm based in Washington, D.C., providing intelligence systems training, integration and implementation and full-spectrum analysis and linguistic capabilities. Argus worked with Palantir to serve U.S. government customers.
Earlier in his career, Barbaccia served as an intelligence sergeant in the U.S. Army and was deployed to both Iraq and Afghanistan.
New Federal CIO
Barbaccia was appointed to the role of federal CIO in January. He succeeds Clare Martorana, who served in the role for four years.
As federal CIO, Barbaccia will oversee the execution of the administration’s technology priorities and ensure the government has access to secure, reliable and high-performing technologies. He is also expected to be involved in the preparation of the government’s IT budget, which will be subject to approval by Congress.
In this capacity, Barbaccia will undeniably have a positive impact on what technologies the government leverages and how it will secure or develop them. The over two decades of professional experience he brings from the military as well as the private sector will also assuredly help him carry out his duties as a key member of the new administration.
As Barbaccia said in a LinkedIn post, “A new chapter begins!” And it is a chapter in which Executive Mosaic anticipates that Barbaccia, as federal CIO, will make significant contributions to the government especially as technology increasingly becomes a decisive factor in national competitiveness and success.
Congratulations to Barbaccia and his team for winning the Wash100 Award!
