Meridian Institute

Advanced technology.
Human purpose.

Meridian applies advanced technology — AI, open-source intelligence, and disciplined analytical frameworks — to reduce the frequency, severity, and human cost of global risk, one problem, one instrument, one measurable outcome at a time.

Purpose
We are not a think tank that publishes reports and waits. We build tools, deploy them, and let the results speak.

The fixed bearing
in a shifting world.

The world's most consequential problems — pandemic, conflict, institutional collapse, food insecurity, democratic backsliding — are not unsolvable. They are inadequately resourced, inadequately coordinated, and inadequately informed. Advanced technology changes each of those conditions.

AI can model an outbreak before it crosses a border. Open-source intelligence can detect a humanitarian crisis in its earliest signal. Structured risk frameworks can tell a policy maker where the next decade's instability is concentrating, and why. These are not hypothetical applications. They are engineering problems waiting for organizational will.

Meridian provides that will — and where possible, the tools themselves. We operate at the intersection of rigorous research, applied technology, and open methodology, guided by one principle: advanced technology should serve the human condition first.

How We Work

Three arms.
One mandate.

01 — Research

Knowledge Products

Systematic reviews, empirical analyses, theoretical frameworks, and policy-facing assessments anchored to peer-reviewed evidentiary standards. Research programs are designed to generate findings that are honest, methodologically documented, and directionally defensible.

Wargames Lab — Multi-modal AI methodology for producing evidence-grounded crisis simulations and tabletop exercises
Institutional accountability at the federal level
Public health infrastructure and biosurveillance systems
Global risk exposure and financial system integrity
02 — Technologies

Operational Platforms

We build and deploy operational tools that measure, monitor, and mitigate global risks directly. Advanced AI, open-source intelligence aggregation, and structured analytical frameworks applied with discipline to reduce the frequency, severity, and human cost of systemic failure.

Cronkite — Epistemic scoring for information environments
Marshall — Country risk intelligence across 217 nations
Snow — Real-time threat surveillance and early warning
Pecora — Ethical investing intelligence and research
03 — Publications

Public Intellectual Work

Long-form analysis, policy argument, and original commentary on the systemic risks that define the current era. Publications are written to be read by serious people who are not specialists — the policymaker, the senior officer, the institutional investor, the informed citizen.

Foresight by Meridian — Research notes, essays, and strategic analysis
Wargames by Meridian — Published wargame scenarios and strategic narratives
Institute Programs

Research in motion.

Meridian Institute houses standing programs that produce primary research, methodology, and analytical frameworks. These are the research outputs that inform the technologies and the publications — and that, in some cases, stand on their own as institutional contributions.

Methodology · Active
Wargames Lab
Multi-modal AI methodology for evidence-grounded crisis simulations and tabletop exercises. Designed for organizations that cannot afford to discover failure points during the emergency itself.
Read the methodology →
Analytical Framework · Forthcoming
Lemkin Framework
A standalone analytical framework examining why documented atrocities sometimes generate sustained civil society mobilization — and sometimes do not. Paired-case design across Darfur (2003–2006) and Sudan (2023–2026). Academic draft complete; publication in preparation.

A Note on Doctrine

Where Meridian stands on force, deterrence, and accountability.

Meridian works at the intersection of advanced technology and global risk. That work is not meaningfully separable from questions about the legitimate use of force, the role of deterrence, and the institutional oversight of advanced capability. A short doctrinal statement sets out where Meridian stands.
