How Microsoft IQ and Rayfin break AI agent data silos for enterprises

Enterprise AI adoption is accelerating faster than governance frameworks can keep pace. Every new agent your team deploys starts from zero, lacking institutional memory or shared context about how the business operates. Microsoft’s latest announcements at Build 2026 directly tackle this fragmentation with two new tools: Microsoft IQ, a unified context layer, and Rayfin, an open-source SDK for deploying agent-built applications into Fabric’s governed backend.

AI agents are creating fragmented ecosystems

Until now, enterprise AI deployments have followed a familiar pattern: teams spin up agents to automate workflows, but each one operates in isolation. These agents lack shared understanding of organizational workflows, institutional knowledge, or real-time business context. According to VentureBeat’s VB Pulse Q1 2026 RAG Infrastructure Market Tracker, hybrid retrieval intent among organizations with 100+ employees surged from 10.3% in January to 33.3% in March, signaling a shift from expanding retrieval coverage to building the underlying architecture that connects these systems.

Microsoft IQ consolidates four critical context sources

Microsoft IQ combines four distinct context sources into a single foundation that any agent can access through a unified integration:

• Work IQ – Derives operational context from emails, documents, meetings, and schedules to model real-world workflows and team dynamics.
• Foundry IQ – Curates institutional knowledge by indexing knowledge bases, procedures, and compliance rules specific to the organization.
• Fabric IQ – Translates live business operations into structured ontologies using Fabric Real-Time Intelligence, with general availability expected in coming months.
• Web IQ – Supplies real-time global context to keep agents informed about external events and market conditions.

"Agents are evolving into highly informed virtual employees," explained Amir Netz, CTO of Microsoft Fabric. "Our responsibility is to create the data-driven reality in which these agents operate."

Rayfin prevents new data silos in agent-built applications

While shared context addresses the first challenge, deployment practices create another: every new agent-generated application needs a backend. Without governance, these applications often route data outside the main platform, reinforcing silos instead of dissolving them.

Rayfin solves this by providing an enterprise-grade backend that deploys agent-built applications directly into Fabric. Application data automatically flows into Microsoft OneLake and feeds back into the Microsoft IQ context layer, ensuring consistency across the ecosystem. Microsoft positions Rayfin against Postgres-compatible alternatives like Supabase and Neon, emphasizing governance as its core differentiator.

"The relationship is bidirectional," Netz noted. "An agent uses the organization’s ontology to build a Rayfin application, and the data generated by that application enriches the ontology for future agents."

The broader industry race for shared context

Microsoft isn’t alone in chasing a unified context layer. Snowflake recently enhanced its semantic capabilities, Pinecone introduced its Nexus platform to expand vector databases into knowledge engines, and Redis launched Iris, a context and memory platform. Each solution reflects the industry’s recognition that RAG and model availability are no longer the primary bottlenecks.

"Fabric IQ and Rayfin address the real enterprise challenge," said Robert Kramer, managing partner at KramerERP. "The question is whether Microsoft simplifies execution and strengthens trust—or adds another layer to an already complex environment."

The success of these tools will depend on execution at scale. If Microsoft can deliver on its promise of unified context and governed deployments, it may offer a blueprint for how enterprises can harness AI agents without falling into the silo trap. The alternative—fragmented, uncontrolled AI ecosystems—risks undermining the very productivity gains these tools are meant to deliver.
