What is an ontology, really?
Most enterprise data lives in silos: a CRM here, an ERP there, support tickets in a third system, spreadsheets everywhere. Each system has its own names and structures for the same things. An ontology is the layer that unifies them into a single model of your business — defining what a "customer" is, how it relates to "orders," "contracts," and "assets," and which rules govern each. It turns scattered tables into a connected map that both people and AI can reason over.
This is the core idea behind Palantir Foundry's ontology and, in the Salesforce world, the unified data model that Data Cloud builds. The technology differs; the principle is identical: give AI a faithful model of reality to act on.
Why grounding matters for AI
The difference is not subtle. In Salesforce's own CRMArena-Pro benchmark, general-purpose language models scored around 35% accuracy on CRM tasks when they could not query the underlying business data directly. Connect the same class of model to grounded records and the accuracy needed for real operations becomes achievable. The model didn't get smarter — it got grounded.
The cost of ungrounded AI
- Hallucinations. An ungrounded agent invents answers confidently. In customer-facing or regulated contexts, that's a liability, not a convenience.
- Stalled pilots. Teams that skip the data step and jump straight to agent configuration rarely hit their projected returns — the agent simply can't see what it needs.
- Eroded trust. One confidently wrong answer in front of a customer undoes months of adoption work.
How grounding works in Salesforce
Salesforce Agentforce grounds agents through Data Cloud. Data Cloud ingests and harmonizes data from across your systems, resolves identities into unified profiles, and provides agents low-latency retrieval through built-in vector search. When an agent needs context, it retrieves the relevant grounded records — a customer's full interaction history, an account's open cases — and reasons over them, rather than relying on the model's memory. The Einstein Trust Layer then governs what the agent may see and do.
The sequence matters: harmonize and unify data first, ground the agent second, deploy autonomy third. Reverse the order and you get a confident agent acting on bad information.
Where to start
You don't need a perfect, enterprise-wide ontology before you see value. Start with the data behind one high-value use case, get it clean and grounded, and prove the agent works there. Then expand the model outward. This is exactly how we sequence engagements: data readiness first, grounded use case second, scale third.

Frequently asked questions
What does it mean to ground AI in data?
Grounding means connecting an AI model to your real, current business data so its responses reflect facts instead of guesses. Rather than answering from general training knowledge, a grounded agent retrieves the actual record — this customer, this order, this case — and reasons over it. In Salesforce, grounding is delivered through Data Cloud and governed by the Einstein Trust Layer.
What is an ontology in enterprise data?
An ontology is a structured model of your real-world business objects — customers, orders, assets, contracts — and the relationships between them. It unifies data scattered across CRM, ERP, and other systems into one connected map that both people and AI can reason over, replacing disconnected tables with a faithful model of how the business actually works.
Why do AI agents hallucinate, and how do you stop it?
Agents hallucinate when they answer from general model knowledge instead of real data. The fix is grounding: connect the agent to unified, normalized records so it retrieves facts before responding. Benchmarks show general models perform poorly on business tasks until they can query grounded data directly, at which point accuracy rises sharply.
