AI-Native Risk Intelligence

for the

Broken World Order

Powered by AI,

Driven by Community

Tesari is an All-Source Intelligence platform —

the “FirstResort” for leaders in high-stakes environments, from trade compliance and supply chain illumination to financial crime and complex litigation.

“The world doesn’t need another Surveillance System

– it needs an Expert Witness.”

Tesari is derived from the Latin testari – “to bear witness” or “provide proof”

As the global order faces unprecedented challenges, mission-critical and evidentiary intelligence has become a first priority.

At Tesari, our mission is to illuminate the gray and dark zones of global networks. Our platform delivers all-source intelligence to provide a complete understanding of the strategic landscape, empowering users to surface the evidence necessary to withstand both boardroom and courtroom scrutiny. 

Tesari AI is evidence-based truth at the speed of AI.

All-source intelligence

Reliable intelligence across all global sources, including exclusive, restricted data from denied regions – delivered in minutes instead of weeks of manual discovery.

Full picture understanding

Cross-border corporate networks, ultimate beneficial ownership (UBO), multilingual news, litigation records, digital footprints, and the dark web – accessed, analyzed, and synthesized in under 3 minutes.

Legal defensibility

Built on rigorous evidentiary standards, source provenance, and 100% auditability – ensuring every insight is fully defensible.

I am collecting on-chain intelligence all day, every day. I have no time for off-chain collection, and OSINT specialists are already incredibly busy. Having a turnkey solution to produce accurate and informative reports satisfies the off-chain intelligence requirements to initialize comprehensive investigations on vendors of interest, such as those selling precursors or dual use components. The reports Tesari produces have already steered my targeting. Without Tesari, I would not be able to quickly identify related entities and take steps to find subsequent critical intelligence on matters of national security for the vast array of countries that rely on me for these insights.

Tesari is an investigation-focused platform that stands out for the level of transparency it provides throughout the search process. The ability to observe, in real time, how queries are executed and exactly where the information is sourced eliminates a level of ambiguity that is common across many tools. That visibility makes source validation and citation far more direct and defensible.


Many platforms return results without clearly disclosing their sources, creating friction when verifying or documenting findings. Tesari addresses this by making attribution accessible and traceable without additional effort.


The platform also produces structured, fully editable investigative reports with strong visual clarity, allowing findings to be reviewed, refined, and presented without extensive reformatting. Just as importantly, it does not introduce unsupported or “phantom” content, which is critical when accuracy and evidentiary integrity are non-negotiable.


Overall, Tesari delivers a more transparent, verifiable, and efficient standard for investigative work.

Tesari is exactly the solution I have been looking for, even before AI fully entered the OSINT space.

When conducting investigations where the analysis of multiple business entities and their extensive personal and capital relationships is a key stage, the volume of information to process grows exponentially. Each additional entity introduces new sources, registries, documents, and leads that must be connected, verified, and translated into meaningful insights.

Tesari helps me keep the entire investigative process on track. I treat it as a new, specialized source of knowledge about the investigated entities and their environment, naturally fitting into my intelligence cycle.

In my work, it serves as an analytical assistant, supporting material review, organizing findings, and identifying connections that would easily be overlooked in a traditional, manual approach.

Particularly valuable is the ability to query specific threads on the fly, discuss conclusions, and test hypotheses directly at the working report stage. This interactive engagement with the dataset significantly accelerates reaching conclusions and enhances the quality of the resulting recommendations.
