Nexarch Labs builds NEXY — cognitive digital twins that decode how people decide, calibrated on biometric and behavioral signals, and deployed through specialized AI agents.
NEXY turns measurable human signals into predictive models of decision-making — from risk appetite and overconfidence to stress response and susceptibility to manipulation.
Literature-grounded cognitive task batteries paired with biometric signals capture how a person actually decides under risk, pressure, and persuasion — not how they say they decide.
Signals are fused into a calibrated computational replica of the individual's decision profile across eight scientifically-defined cognitive domains.
Specialized AI agents query the twins to forecast decisions, stress-test scenarios, and flag cognitive vulnerabilities — in defense, finance, and consumer settings.
The same cognitive twin engine, specialized by domain.
Cognitive survivability for operators and societies.
Markets move when people decide. We model the people.
Test on replicas before you spend on reality.
Neuroscience for the works that move people.
Our task batteries build on decades of peer-reviewed behavioral science — established experimental paradigms, not ad-hoc quizzes.
Behavior, physiology, and self-report anchored against each other, so the twin reflects what people do — not just what they report.
EU-built deep tech serving both security and commercial markets, designed for data sovereignty and responsible deployment.
Provider-agnostic multi-agent AI stack purpose-built for cognitive modeling — no off-the-shelf wrappers.
From controlled experiments to operational environments: the same models, hardened for real-world signal quality.
Cognitive data is sensitive by definition. Consent, minimization, and auditability are designed in from day one.
Whether you're a defense innovation programme, an investor, a research partner, or an enterprise exploring cognitive twins — we'd like to hear from you.
