A RAG development company that ships accurate retrieval

We build production retrieval-augmented generation systems that answer from your private data with citations — engineered for accuracy, not impressive-but-wrong demos.

What this means for your business

Retrieval-augmented generation lets an LLM answer from your private documents instead of guessing. Done badly, it confidently invents answers. Done right, it grounds every response in your real content, with citations, and tells you when it does not know.

The difference is engineering: smart chunking, the right embedding model, hybrid keyword-plus-vector search, reranking and a relentless eval loop. That pipeline is what we build, and it is the same approach behind our own production products that answer user questions reliably.

You get a RAG system that is measured, not vibes-based: retrieval quality and answer accuracy are scored on a test set, and we tune until the numbers hold. The outcome is a knowledge system your team and customers can actually trust.

What we build

1

Smart ingestion

Document parsing and chunking tuned to your content so retrieval has the right context.

2

Hybrid search

Vector plus keyword search with reranking to surface the most relevant passages.

3

Grounded answers

Responses cite the source passage and abstain when the answer is not in your data.

4

Eval harness

Retrieval and answer-quality scored on a test set so accuracy is measured, not assumed.

5

Access control

Per-user and per-document permissions so people only retrieve what they are allowed to see.

6

Freshness pipeline

Automated re-indexing so the system stays current as your documents change.
