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.
XSI-AIMS
Agent Instrumentation and Management — an open governance specification for agentic systems. Substrate-agnostic. Model-agnostic. Deployment-agnostic.
Read the spec →XSI-AIMS Atlas™ + XSI-AIMS Compass™
Commercial implementations from XSI, contact-gated from day one: a memory routing engine across the XSI-AIMS memory subsystems, 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 XSI-AIMS.
See the portfolio →An open standard for agentic systems.
XSI-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 public agent registry, commercial implementations from XSI — XSI-AIMS Atlas and XSI-AIMS Compass — and the conformance principle: every required feature is present in any conformant implementation; how each feature is delivered is the implementer's IP.
XSI-AIMS is being offered to standards bodies under consideration: NIST, IETF, W3C, OASIS, and MCP. Submissions begin after the June 2026 release.
Six products. One standard.

Microsoft approved the first substrate runtime of XSI-AIMS for listing on AppSource. The listing follows on its own beat.
Why ISPs are the ideal AI market
ISPs have the data, the customer base, and the local presence. They also have the regulatory pressure that makes sovereign agentic AI a fit.
