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.
Research-grade hardware teaches each twin once in the lab; the field then runs on two wearables and outputs a single Decision Quality Index.
A hard anti-neurofeedback rule applies — operators never see live physiology; only the supervisor view does. STANAG 4677/4774 compatible.
The same cognitive twin engine — hardened for security, productised for commercial markets. Pick a side, then explore the capabilities.
A live read on whether an operator can still decide well under load — the Decision Quality Index.
Detect and blunt cognitive attacks on people and populations.
Select, train and optimise human performance from measured cognition.
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.
