XenonStack builds Decision Infrastructure, the governed AI stack for regulated enterprises. When an AI agent acts, you can show what it decided, on what data and under which policy. Four products, one platform: ElixirData (Context OS: context graph, evidence and decision trace), ElixirClaw (build, run and operate agents and MCP tools), AgentGRC (policy, risk and compliance for every agent decision) and NexaStack (physical AI and sovereign, edge deployment). Built for banking, healthcare, government and industry. Runs on AWS and what you already have.
