AI agents and grounded RAG

We build agents and retrieval systems that answer questions over your own documents and data. The difference is grounding: every answer is read from a real record and traceable to its source, and the system abstains when the data is not there rather than fabricate a figure. That approach has a name, grounded RAG: retrieve from your records first, then answer only from what was found.

What it includes

  • An orchestrator that routes each question to the right specialist agent
  • Hybrid retrieval with a reranking stage, and cited answers down to the record
  • An abstain path, so an ungrounded question gets an honest no-answer

What you get

  • A working agent or ask-anything surface over your data
  • A citation trail from every answer to its source document or row
  • A retrieval setup you can extend as your corpus grows

Common questions

How do you stop the agent from hallucinating?

Answers are grounded in retrieved records and checked by a multi-stage verifier before they are served. When a claim cannot be traced to a source, the system abstains.

How large a corpus can this handle?

We have run this over more than 29 million indexed chunks with cited retrieval. The same setup extends to a larger corpus without a rebuild.

Can it keep one client's data out of another's answers?

Yes, and we measure it. On one production system we hold zero cross-tenant leaks across both embedding spaces, verified by the eval gate.
