Tesari exists to build software that honors true investigators: corporate intelligence teams, risk and compliance professionals, investigative journalists, and national security analysts.

We believe they do some of the most important work of our time: protecting institutions from emerging threats, safeguarding critical supply chains, and exposing risks that remain invisible across borders. Our role is to arm these practitioners with AI that gives them an asymmetrical advantage over the adversary.

Tesari AI provides immediate access to critical intelligence, all-source analysis, and defensible evidence. By combining integrated global and local data with AI-native, jurisdiction-specific tradecraft, our platform delivers structured intelligence of “First Resort,” allowing practitioners to see the full picture in minutes and decide where to go deeper with confidence.

We reject the 'black box' status quo. Our mission is to scale—not replace—human judgment through a 'glass box' architecture. By exposing the underlying logic, entity resolution ontologies, and source provenance, we ensure every insight is firmly under the practitioner's control, by design.

Engineered by a team of tradecraft practitioners, senior engineers, and ethical hackers who previously built tech for elite government agencies and participated in global investigations into illicit finance, human trafficking, war crimes, sanctions evasion, and influence operations.

Backed by former senior executives from Meta, Deutsche, LexisNexis and the CIA.
