Arcanum Global and Tesari AI Partner to Advance High-Stakes Intelligence Investigations
September 24, 2026 — McLean, Virginia
Arcanum Powered by Tesari combines government-grade human intelligence with specialized AI and proprietary data to expand investigative reach and speed.
Arcanum Global Intelligence (AGI) and Tesari AI today announced a strategic partnership to enhance intelligence-led investigations in some of the world’s most challenging and information-constrained regions.
Arcanum Powered by Tesari combines Arcanum’s decades of government-grade human intelligence and high-stakes investigative experience with Tesari’s specialized artificial intelligence, proprietary data access, and technology for collecting and validating intelligence across borders.
The partnership is designed to help government entities, defense leaders, transnational corporations, and select corporate clients address complex geopolitical, regulatory, and security risks with greater speed, reach, and depth.
As cross-border investigations become increasingly complex, critical information about ownership, control, affiliations, and relationships can remain fragmented or difficult to access—particularly in restricted regions. Arcanum and Tesari are combining their industry leading expertise in human intelligence and specialized AI to help investigators identify connections, close information gaps, and develop a more comprehensive picture of the risks surrounding an individual, organization, or transaction.
“AI can never fully replace human decisions,” said Elisar Nurmagambet, Founder and CEO of Tesari. “Our goal is to build a platform that becomes a multiplier, bringing hundreds of eyes, hands, and ears to Arcanum’s experts, so they can see where no one else can, collect fragmented intelligence faster than anyone else, and uncover hidden insights deeper than ever before.”
Amy McFadden, Senior Vice President and Head of Arcanum’s Strategic Intelligence Group, said the partnership combines advanced technology with the human judgment and all-source intelligence tradecraft required for high-stakes investigations. “Arcanum Powered by Tesari brings together two things that rarely coexist at this level: sophisticated AI engineering and decades of human judgment earned in the field,” said McFadden. “The depth of Tesari’s tradecraft-aware technology and data access matches the standard Arcanum has upheld throughout its history supporting high-stakes national security investigations and clients.” McFadden is a former CIA and ODNI executive, Vice Chair for Strategic Engagement at the National Intelligence Council, and Director of the President’s Daily Brief.
