What is Hardalion?
Hardalion builds foundational infrastructure that safely bridges probabilistic AI models with deterministic operational systems across finance, healthcare, and critical infrastructure.
Founded in 2025, Hardalion is an infrastructure company serving regulated industries worldwide. We develop the Nexus Execution Protocol, an open-source deterministic commit boundary that evaluates AI agent intents before they reach operational systems in finance, healthcare, and critical infrastructure.

What products does Hardalion offer?
Hardalion offers two products: NEP (protocol infrastructure for regulated AI) and FinFlow OS (consumer financial management). Both run on shared platform rails.
Nexus Execution Protocol (NEP)
Universal deterministic commit boundary for high-risk AI with Domain Energy Plugins for finance, healthcare, and defense.
FinFlow OS
AI-powered financial management for freelancers and gig workers - a consumer product built on Hardalion platform rails.
What is the Nexus Execution Protocol?
The Nexus Execution Protocol (NEP) is an open-source deterministic commit boundary for high-risk AI. It evaluates agent intents through Domain Energy Plugins before any action reaches downstream systems.
Frequently asked questions
What is Hardalion?
Hardalion is a company that builds foundational infrastructure for high-risk AI execution. Its flagship product is the Nexus Execution Protocol (NEP), an open-source deterministic commit boundary that sits between probabilistic AI models and operational systems in regulated industries.
What is the Nexus Execution Protocol (NEP)?
NEP is Hardalion's universal execution protocol for high-risk AI. It ingests probabilistic agent intents, evaluates them against policy-as-code via Domain Energy Plugins (@nexus/finance, @nexus/healthcare, @nexus/defense), and only commits actions that pass deterministic compliance checks. When violation energy e > 0, execution is blocked.
What industries does Hardalion serve?
Hardalion targets regulated domains: finance (institutional workflows, transaction controls), healthcare (EU AI Act alignment, EMR safety), and defense/critical infrastructure (Rules of Engagement, dual-key signatures). The same NEP core engine powers all domains via pluggable rule sets.
Is NEP open source?
Yes. The Nexus Execution Protocol specification and core engine are open source. Enterprise deployments and Domain Energy Plugins are available through Hardalion's private deployment program.
What is FinFlow OS?
FinFlow OS is a live consumer product at finflow.hardalion.com - AI-powered financial management for freelancers and gig workers. It runs on Hardalion platform rails (identity, API keys, entitlements, audit) but is separate from the NEP protocol product.
