Document Ingestion
The ingestion pipeline — file types, parsing, normalisation, the metadata the retrieval needs.
AI + Data
Retrieval-Augmented Generation (RAG) for AI that needs to know your documents — the ingestion, the chunking, the embeddings, the retrieval, the reranking, the eval suite, the guardrails and the cost controls that make RAG safe enough to ship to a customer.

Overview
RAG (Retrieval-Augmented Generation) is the work of making an AI model answer from your documents instead of from its training data. The work is the ingestion, the chunking, the embeddings, the retrieval, the reranking, the prompt, the eval suite and the guardrails. The prompt is one component, the system is the product.
We build RAG systems with the ingestion, the chunking, the embeddings, the retrieval, the reranking, the eval suite, the guardrails and the cost controls as part of the architecture from sprint one. The output is a RAG system that answers correctly, cites the source and is safe enough to ship to a customer.
This is the wrong engagement if the documents are not yet in shape, or if the use case is classification (not question-answering). We will say so on the call.
What we deliver
The ingestion pipeline — file types, parsing, normalisation, the metadata the retrieval needs.
The chunking strategy, the embeddings model, the metadata the retrieval needs.
The retrieval, the reranking, the hybrid search, the citations the answer needs.
The prompt, the context window, the citation, the generation the RAG answer needs.
An evaluation suite, the safety filters, the citation accuracy and the guardrails.
The production deploy, the observability, the cost review and the model swap path.
Our process
01
Discover
We audit the documents, the access control, the questions and the accuracy the use case needs.
02
Plan & Design
We design the ingestion, the chunking, the retrieval, the prompt and the eval suite.
03
Develop
We build in two-week sprints with the team testing as we go.
04
Deploy
We ship to production with the eval, the guardrails and the observability live.
05
Optimize & Grow
We read the accuracy, the eval and the team feedback, and ship the next iteration.
Technology
What you can expect
Industries we serve
It depends on the documents, the chunking, the retrieval and the eval suite. For a well-structured document set with a good chunking strategy, 90%+ citation accuracy is a reasonable target. The accuracy is measured against a held-out test set, not a guess.
Per-user access control is part of the architecture. The documents are filtered to the user the answer is for, the retrieval only sees the documents the user can see, and the generation only cites the documents the user is allowed to read. The access control is enforced at the retrieval layer, not the prompt layer.
The chunking strategy is part of the architecture. For structured documents (invoices, contracts), fixed-size chunks with metadata work. For unstructured documents (articles, books), semantic chunks with overlap work. The chunking is tuned against the eval suite, not a guess.
Yes. The vector store, the embeddings and the model can all run on your infrastructure, with the deployment model agreed in the discovery. For sensitive data, the documents never leave your VPC, and the RAG system runs on your hardware, with the same engineering rigour as the rest of the system.
