The knowledge layer for trustworthy AI
Your enterprise AI systems are only as good as the context behind them. The knowledge layer gives your AI what it needs to be accurate, explainable, and governable.
What’s missing from enterprise AI
“Without relationships at the center, AI will remain what it is for most organizations today: an expensive experiment.”
Gartner analyst Georgia O’Callaghan,
March 2026
Organizations are investing heavily in AI to drive better decisions, lower costs, and strengthen customer experiences, but most AI initiatives fail to become usable infrastructure.
That’s because AI needs to understand how and why things connect, not just access the data.
A knowledge layer gives it that context.
What is a knowledge layer?
The knowledge layer sits between your data and the AI models and agentic systems built on it — connecting facts to the relationships, history, and rules that govern them. That’s what lets your AI move past simple lookups into real reasoning and memory.
What organizations get from a knowledge layer
For business leaders
Trustworthy AI that stands up to scrutiny.
- Trust every AI answer, traced back to your source data
- Prove every AI decision with a complete audit trail
- Synthesize intelligence across disparate data systems and teams
- Make use of your existing data investments instead of replacing them
For technical teams
Infrastructure and tools to build AI agents and systems that work in production.
- Generate grounded answers by combining semantic search with graph retrieval
- Build agents that remember, with native short-term, long-term, and reasoning memory
- Leverage integrations with the AI, infrastructure, and tools you already use
- Access data where it lives, unified by a semantic model across sources

Where the knowledge layer meets the real world
Organizations across every industry are investing in AI. The difference between AI that reaches production and AI that stays in pilot comes down to whether it actually understands the business it’s running in.
Risk, fraud, and cybersecurity
Fraud rarely comes from one account acting alone. It hides across networks of shared devices, linked identities, and coordinated transactions, making it hard to spot. The knowledge layer helps AI uncover those hidden connections in real time, rather than just flagging a transaction after it’s too late.
Customer experience and personalization
When a customer calls support, their whole history — past purchases, issues, preferences — usually lives in different places. The knowledge layer pulls it into one clear picture, so agents and customer-facing teams can respond to who the customer actually is, not just the ticket in front of them.
Enterprise automation and agentic workflows
Say an AI agent needs to onboard a new hire or resolve a support ticket. To do that well, it needs to understand how your company works — but that knowledge is usually scattered across dozens of systems. The knowledge layer brings it together, so agents act on what your company actually knows, not just what they can dig up.
Supply chain and operations
Supply chains are networks of dependencies scattered across different systems. The knowledge layer keeps that network connected and current, so teams and AI agents can act fast when a shipment is delayed or rerouted, before the disruption reaches the business.
Product and R&D acceleration
Getting a product from concept to market requires drawing on knowledge that’s spread across an organization, including research, prior decisions, specifications, regulatory requirements, and domain expertise. The knowledge layer connects it all, so AI helps teams build on what’s already known rather than rediscovering it.
Forecasting and decision intelligence
A sales forecast, risk assessment, or resource plan is only as good as the relationships it accounts for: how customers, markets, competitors, and past decisions connect to right now. The knowledge layer helps AI reason across those relationships, so forecasts and decisions reflect what’s actually happening, not just the obvious data points.
