The ontologyyour AI runs on.
Tacit models your company’s data, rules, processes and actions in one place, so every person and every AI agent works from the same reality.
A digital twinof your business.
Your ontology holds your data, rules and actions in one place, checked before anyone relies on them, so people and AI get the same answer.
What does an ontology capture?
01Data
Connect every system once.
ERP, CRM, documents and spreadsheets become one connected picture of your business.
02Logic
Write the rules down.
What counts as a late order or a good margin is defined once and checked before anyone relies on it.
03Actions
Let AI act, with approval.
Actions run through approvals and are written back to your systems, like SAP.
04Governance
Govern people and agents alike.
The same permissions apply to every person and every AI agent.

Put your ontologyto work.
Every app runs on the same model of your company, so answers agree and actions follow your rules.
Ask in plain words and get the answer from your own data, with every step shown.
Book a callSee where your team’s time goes, find the repetitive work, and let AI take it over.
Your ontology gives every agent its context: data, rules, approvals and processes. Your developers build the rest in Claude, Cursor or Copilot.
The spec writes itself from what the ontology knows, then ships into your product.
They notice what needs attention and set the right actions going across your tools; a person approves what matters.
An ontology does more than power AI.
Once your company is written down, it pays off in places you might not expect.
