Taking agentic systems further.
Supervised. Accountable. Sovereign.
An open standard for agentic governance — and the portfolio of sovereign products built on it.
Three things, one strategy.
XSI builds the standard, the instruments that prove it, and the products that ship it. Each pillar supports the others.
AIMS
Agent Instrumentation and Management — an open governance specification for agentic systems. Substrate-agnostic. Model-agnostic. Deployment-agnostic.
Read the spec →AIMS Atlas + AIMS Compass
A reference toolkit AIMS adopters get for free: a memory routing harness across five memory types, and a model router that picks the cheapest model meeting each call's requirements.
Atlas → Compass →Sovereign products
XSI LodeStone, XSI-AIMS for the Microsoft Agent Framework, XSI AIMS Advisor for Azure Sovereign AI, and XSI BlindSpot — each a reference deployment of AIMS.
See the portfolio →An open standard for agentic systems.
AIMS is a supervisory governance framework, not a runtime. It is substrate-agnostic, model-agnostic, and deployment-agnostic. XSI authored it and is community-owning it by intent.
v2.0 ships with the spec, the reference toolkit (AIMS Atlas and AIMS Compass), the agent registry, and the conformance principle: every required feature is present in any conformant implementation; how each feature is delivered is the implementer's IP.
AIMS is being offered to standards bodies under consideration: NIST, IETF, W3C, OASIS, and MCP. Submissions begin after the June 2026 release.
Four products. One standard.
