RAG Pipeline Development

The RAG pipeline development company behind answers you can trust

BinaryBrill is a RAG pipeline development company that builds the retrieval infrastructure grounding LLM answers in your own documents — ingestion, parsing, chunking, embeddings, vector search, re-ranking and retrieval evaluation. You get retrieval augmented generation development from in-house senior engineers, with permission-aware retrieval so an enterprise knowledge base AI only ever returns what each user is allowed to see.

Why grounded answers still come out wrong

The assistant sounds confident and cites the wrong document

The generation half works — the answer reads fluently. But it was built on the wrong passage, because nobody measured whether retrieval fetched the right source in the first place. A fluent answer over the wrong document is the most dangerous output a retrieval system produces, and it's invisible until someone who knows the material reads it.

Search returns forty documents and none of the right one

The knowledge base runs on keyword matching, so a query phrased differently from the document misses it entirely, and a common word drags back everything. Staff give up and ask a colleague, which defeats the point of building the thing. Vector-only search has the opposite failure — it drifts on exact terms, codes and names.

Users can retrieve answers from documents they shouldn't see

Retrieval was bolted on without the permission model, so the index treats every document as equally visible. Now a query can surface a passage from an HR file, a restricted contract, or another team's folder. In an enterprise knowledge base that isn't a bug, it's an incident.

The answers are six months out of date

The pipeline ingested everything once at launch and never again. Documents changed, new ones landed, old ones were retired, and the index kept serving the stale version with total confidence. Without a freshness and re-indexing strategy, a retrieval system quietly rots while looking exactly as authoritative as the day it shipped.

How a RAG pipeline development company builds retrieval that holds up

This page is about the retrieval infrastructure, not the chatbot or copilot on top of it — those apps consume what the pipeline returns. We build the pipeline so that what it returns is the right passage, the current version, and only what the user is allowed to see, and we prove it with evaluation rather than a good-looking demo.

Retrieval measured before generation is trusted

We build a scored retrieval set with known-correct sources and measure whether the pipeline actually fetches them, using tools like Ragas, before anyone judges the generated answer. Recall and precision on retrieval are numbers we track on every change, so a tweak that helps one query can't silently break ten others.

Hybrid search and re-ranking, not vector-only defaults

Keyword search catches exact terms, codes and names; vector search catches meaning and paraphrase. We combine them and add a re-ranking pass so the most relevant passage rises to the top, tuned to your content rather than left on library defaults that were never meant for your documents.

Permission-aware retrieval built in from the start

Entitlements are enforced at retrieval time, not filtered after the fact: the pipeline only ever considers passages the current user is allowed to see. For an enterprise knowledge base that draws from SharePoint, Confluence and shared drives, this is the difference between a useful tool and a data-leak waiting to happen.

Freshness treated as a first-class requirement

Content changes, so the index has to as well. We build re-indexing that tracks document additions, edits and deletions on a schedule or on change, so answers reflect the current source. A retrieval system that can't stay current is one people stop trusting the first time it cites something that was retired.

What this covers

Pick the piece you need, or bring us the problem and we'll tell you which applies.

Ingestion, Connectors & Parsing

The pipeline starts by getting your content in cleanly. We build connectors to SharePoint, Confluence, Google Drive, object storage and databases, with parsing that survives the formats real enterprises hold — tables, scanned PDFs, multi-column layouts and mixed encodings — because retrieval quality is capped by how well the source was read in the first place.

  • Connectors to SharePoint, Confluence, Google Drive, S3 and databases
  • Parsing that handles tables, scanned PDFs and multi-column layouts
  • Incremental ingestion that picks up new, changed and deleted documents
  • Metadata capture — source, author, date, permissions — carried through the pipeline

Chunking, Embeddings & Vector Databases

How documents are split and embedded decides what retrieval can find. We test chunking strategies against your content rather than defaulting to a token count, choose an embedding model suited to your domain, and select the vector database that fits your scale and infrastructure — pgvector where it's enough, a dedicated store where it isn't.

  • Chunking strategy chosen against your content and scored, not left on defaults
  • Embedding model selection matched to your domain and languages
  • Vector database selection across pgvector, Pinecone, Weaviate and Qdrant
  • Re-embedding handled cleanly when documents or the model change

Hybrid Search & Re-ranking

Vector search alone drifts on exact terms, codes and names; keyword search alone misses paraphrase. Our retrieval augmented generation development combines both and adds a re-ranking pass, so the passage that actually answers the question rises above the ones that merely mention the right words.

  • Hybrid keyword and vector retrieval, weighted and tuned to your content
  • Cross-encoder re-ranking so the most relevant passage surfaces, not just a plausible one
  • Handling for exact identifiers — part numbers, clause references, codes
  • Query preprocessing and expansion where it measurably improves recall

Retrieval Evaluation

This is what separates a serious RAG development company from a weekend prototype. We score whether the right passage was retrieved — not just whether the answer sounded good — using Ragas and a ground-truth set built from your content, and we track those numbers on every change so regressions are caught before your users find them.

  • A ground-truth question set with known-correct sources, built from your material
  • Retrieval recall and precision measured, with Ragas and custom metrics
  • Scoring wired into every change so a tweak can't silently regress retrieval
  • Ongoing monitoring so retrieval quality is watched after launch, not assumed

Permission-Aware & Fresh Enterprise Knowledge Base AI

For an enterprise knowledge base AI, two things decide whether it's safe to deploy: users must never retrieve what they can't see, and answers must reflect current documents. We enforce entitlements at retrieval time and build re-indexing that keeps the pipeline in step with changing content, so the system stays both secure and current.

  • Entitlements enforced at retrieval time, filtered before results are ever assembled
  • Permission model mapped from SharePoint, Confluence and your identity provider
  • Re-indexing on schedule or on change so answers track the current source
  • Retirement handling so deleted or superseded documents stop being retrieved

How we'll work together

Every stage ends with something in your hands — not a status update.

  1. 01

    Source and access audit

    We inventory the content sources in scope — SharePoint sites, Confluence spaces, drives, databases — their formats, and crucially their permission model, because who may see what shapes the whole design. We also agree the retrieval test set that will tell us later whether the pipeline works.

    You get: A source inventory with formats and volumes, a permission mapping per source, and an agreed plan for the retrieval evaluation set.

  2. 02

    Ingestion, parsing and chunking pipeline

    We build the connectors that pull content in, parsing that survives tables, scanned PDFs and multi-column layouts, and a chunking strategy chosen against your content rather than a default token count. Alongside it we assemble a labelled ground-truth set your subject-matter experts validate.

    You get: A running ingestion pipeline with monitoring, connectors to your sources, and a validated retrieval ground-truth set signed off by your experts.

  3. 03

    Retrieval, re-ranking and evaluation

    Embedding choice, vector database, hybrid search weighting and the re-ranking pass each become an experiment scored against the ground-truth set with Ragas and custom metrics. We keep what raises retrieval recall and precision and discard what merely improved a demo, then expose the result as a clean API for your apps to consume.

    You get: A tuned retrieval service meeting the recall and precision bar agreed in step one, an evaluation report, and a documented API for the apps that will consume it.

  4. 04

    Permissions, freshness and handover

    We wire permission-aware filtering into retrieval, set up re-indexing so the index tracks changing documents, and instrument the pipeline so retrieval quality is monitored after launch rather than assumed. Then we hand over documentation written for an engineer who wasn't on the project.

    You get: The production pipeline with permission enforcement, a re-indexing schedule, evaluation and monitoring dashboards, and an operator runbook.

Where we've applied this

Professional services

Institutional memory across proposals, contracts and project files, with retrieval scoped so a junior can't surface a partner-restricted document.

Finance

Policy and regulation retrieval that cites the clause it answered from, filtered by desk and jurisdiction so each user only sees what applies to them.

Healthcare

Retrieval across protocols and formulary documents where every passage links to its source page and access follows the user's clinical role.

Manufacturing

Retrieval over manuals, SOPs and maintenance logs so a technician finds the current procedure rather than a superseded revision.

Legal

Contract and precedent retrieval with matter-level permissions, so a knowledge base never lets one client's material cross into another's answers.

Technology & SaaS

Retrieval over product docs, tickets and internal wikis so a support surface answers from current material, not last year's release notes.

Questions buyers ask us

How is a RAG pipeline different from the chatbot or app that uses it?

The pipeline is the retrieval infrastructure; the chatbot, copilot or app is the surface that consumes what it returns. This page is specifically about the pipeline — ingestion, chunking, embeddings, vector search, re-ranking, evaluation, freshness and permissions. The assistant that shows answers to users is a separate build, covered under LLM App Development and Chatbot Development. The two are often delivered together, but the retrieval quality is decided in the pipeline, which is why it's worth treating as its own piece of engineering.

Very likely, because most hallucination in a knowledge assistant is a retrieval problem wearing a generation costume. If the pipeline hands the model the wrong passage, or no passage, the model fills the gap with something plausible and wrong. Fixing the prompt rarely helps; fixing retrieval usually does. We can assess your existing setup, measure whether it's actually fetching the right sources, and rebuild the pipeline underneath the chatbot you already have without replacing the whole application.

We measure it, which is the part most RAG projects skip. We build a ground-truth set of questions with known-correct sources from your own content, then score whether the pipeline retrieves those sources — recall and precision on retrieval — using Ragas and custom metrics. That score runs on every change, so improvements are demonstrated rather than asserted and regressions get caught before users do. Judging a retrieval system by whether the first answer sounded convincing is how wrong-but-fluent answers reach production.

Not when permissions are built into retrieval, which is how we build it. Entitlements are enforced at retrieval time, so the pipeline only ever considers passages the current user is allowed to see — filtering happens before results are assembled, not after. We map the permission model from your sources, such as SharePoint and Confluence, and your identity provider. Treating permissions as an afterthought is the most common way an enterprise knowledge base turns into a data-leak incident, so we design for it from the audit onward.

It depends on scale, infrastructure and operational appetite, and we decide after those are clear rather than by default. Postgres with pgvector is often enough and keeps everything in a database you already run; a dedicated store like Pinecone, Weaviate or Qdrant earns its place at larger scale, higher query volume or when you want managed operations. Because the pipeline sits behind a clean interface, the vector database is a component we can benchmark and swap, not a decision that locks you in.

With a re-indexing strategy built into the pipeline rather than a one-off ingestion at launch. We track additions, edits and deletions in your sources and re-index on a schedule or on change, so the index reflects the current document and retired content stops being retrieved. Freshness is a first-class requirement in how we build, because a retrieval system that silently serves last year's version while sounding authoritative is worse than no system at all.

The main drivers are the number and messiness of your sources, the parsing difficulty of your formats, the accuracy bar you're targeting, and whether permission-aware retrieval is in scope — enforcing entitlements across several systems is real work. A focused pipeline over a clean, single source with a scored evaluation set is usually a few weeks; a broader enterprise build across multiple connectors with permissions and freshness runs longer. Running cost is mostly embedding and inference per query, which we model during design.

More often than the hype suggests. If the answer is a structured lookup — a status, a balance, a record — a database query is faster, cheaper and exact, and dressing it up as retrieval adds nothing. If your content is contradictory or badly out of date, retrieval will confidently cite the wrong version, so the data has to be sorted first. And if there's no correct answer already written down anywhere, retrieval has nothing to ground on. We'll tell you during the audit if one of these applies rather than build you a pipeline that can't succeed.

They stay within your environment and accounts wherever the architecture allows, and they aren't used for anything outside your project. Where a hosted embedding or model provider sits in the design we tell you exactly which one, what leaves your infrastructure, and what their retention terms are before you approve it — and open-weights embedding models deployed inside your own network are an option when nothing may leave at all. The index we build is yours, on infrastructure you control.
