The new era of investigations

Our goal is to deliver credible "Intelligence of FirstResort” - powering all work streams and informing critical decisions, while keeping humans at the helm and in control of every step.

The platform delivers mission-critical intelligence and cuts through massive amounts of data to get a clear picture and helps you find solid, verifiable evidence that you can rely on.

Capabilities

Jurisdictional Coverage

Trained to conduct deep investigative searches aligned with local context, language and regulatory frameworks across regions worldwide.

Specialized Web Search

Structured searches across open web, applying advanced filtering and contextual logic.

Regional Sources

Access regional databases, local registries, and trusted data providers that cannot be discovered through a general approach.

Local Context

The agent accounts for local laws, naming conventions, transliteration variations, registry structures, and region-specific content to ensure accurate and context-aware investigative results.

All-in-One Platform

A wide range of data sources and tools in one place – from official registries to SOCMINT.

All Data Levels in One Place

We combine data across four critical levels to power your investigations:

Official: Primary government records with high legitimacy.

Verified: Cross-referenced data confirmed factual via Tesari analytics.

Non-Authoritative (Unverified): High-value investigative leads from non-official sources.

Multiple Integrations

Single access to over thousands of data sources worldwide: regional corporate data, import-export, litigation, sanctions, OSINT, dark web, crypto, global and local news, digital footprint. 

Access to Exclusive Data

Unique and high-value intelligence:

Beyond-reach data: access to critical data from denied regions, including China and Russia.

Deep, Localized Coverage: native insight from local government datasets and local media.

Deep Structural Insight: essential data for Global Trade Data; UBO identification; Court Records.

AI Copilot

Built for live, mission-critical investigations, the AI Copilot works alongside investigators to navigate case files, resolve key questions, synthesize evidence, and uncover strategic insights in real time.

Search through Raw Data

You can explore raw data directly through the AI Copilot by asking targeted questions to uncover additional insights.

Tesari collects and structures thousands of raw data points enabling deeper investigative exploration when needed.

Prompt Complex Tasks

The AI Copilot is trained to think like an investigator. Upon your request, it extracts and structures key entities, builds timelines and network maps, identifies indirect links, surfaces underlying evidence, and recommends strategic next steps.

Collaborative Analysis

Instead of generating a static report, you can ask follow-up questions, challenge assumptions, request deeper dives into specific entities, and explore alternative hypotheses in real time.

Fully Traceable

Unlike others, Tesari provides a fully traceable investigative workflow, marking data with references and links to original sources. This makes it suitable for implementation into standard and official workflows.

Raw Data Files

Full transparency and control.

Instead of relying solely on a summarized case file, you can access the underlying data and trace every step of the investigation.

Evidence

Tesari helps you find solid, verifiable evidence through All-source intelligence that you can rely on.

Evidence

A structured set of live source links directly connected to each finding, allowing you to verify the information and review the original context.

Our guiding principle behind product development:

AI will never replace an investigator’s analytical mind, instinctive judgement, or objective integrity. Tesari exists to automate the painstaking parts of the job, so that investigators can operate without limits.
