Expertise / Knowledge & Retrieval

Grounded answers. Not guesswork.

Most enterprise RAG demos work on a clean corpus and fall over the moment they meet real data, real questions, and real users. We build retrieval systems engineered for grounding — hybrid retrieval, reranking, context engineering, and evaluation that holds up against your actual workflows.

Why most RAG breaks in production.

Enterprise intent for hybrid retrieval tripled in a single quarter of 2026 — a signal that the original retrieve-then-generate pipeline is failing at scale. Production RAG isn’t a vector DB; it’s an engineered context system, and most teams are missing the engineering.

Naive retrieval, naive answers

Top-k embedding search misses the question entirely on enterprise corpora. Without hybrid retrieval, BM25 fallback, and metadata filters, you get plausible-sounding but ungrounded responses — the demo passes, the audit doesn’t.

Context overload

Stuffing the window with irrelevant chunks degrades answer quality. Without a reranker and a context budget, the model drowns in noise — and the operator stops trusting the citations.

No way to measure correctness

Faithfulness, context precision, context recall — most teams run none of them. You can’t improve what you can’t measure, and “looks right” isn’t a deployment criterion.

Stale, ungoverned indexes

Documents change, access changes, classification changes — and the index doesn’t. Without lifecycle management and permission-aware retrieval, you have a data leak waiting to happen.

Context engineering, not chunked search.

Retrieval is one piece. Production-grade systems engineer everything between the question and the answer.

  • Understand the query. Decomposition, rewriting, and routing by intent — complex questions are broken into retrievable parts before they touch the index; trivial ones skip the heavy machinery.
  • Hybrid retrieval over real data. Dense embeddings plus BM25, with metadata filters and permission scopes. Vector store matched to your scale and residency — Pinecone, Weaviate, Qdrant, Milvus, or pgvector.
  • Rerank against the question. Multi-stage reranking with cross-encoders (Cohere Rerank, Voyage AI) cuts context to what actually answers. Non-optional in production.
  • Engineer the context window. Citation-preserving chunking, structured prompt assembly, and context budgeting — with a GraphRAG layer (Neo4j or equivalent) where relationships matter.
  • Evaluate continuously. Faithfulness, answer relevance, context precision and recall — RAGAS or a custom harness, run every release against your real questions.

Retrieval patterns we ship.

Three production retrieval patterns — each engineered for a different shape of question and a different shape of corpus.

01

Enterprise search & assistant systems

Grounded Q&A over policies, manuals, contracts, tickets, and internal documentation. Citations and audit trail by default. Permission-aware from the first query.

02

Agentic retrieval

Multi-hop, tool-using retrieval for complex questions that need decomposition, lookup, synthesis, and verification. The retriever becomes an agent, not a single shot.

03

GraphRAG over structured knowledge

Knowledge-graph-enhanced retrieval for domains where entities and relationships matter — regulated finance, pharma, complex sales, legal. Measured above 81% accuracy in specialized domains.

What we engineer around the retrieval.

The retriever is one piece. These are the layers that make it trustworthy in production.

01

Hybrid retrieval architecture

Vector plus lexical plus structured, with metadata filters and access controls. The index becomes a first-class system, not a side car.

02

Evaluation harness

Faithfulness, grounding, context precision, drift — with regression testing every release. RAGAS, custom harnesses, or both, grounded in your real questions and real failure modes.

03

Lifecycle & governance

Index refresh, permission propagation, citation integrity, PII protection. The retrieval system stays current with the source of truth — and inside your access policies.

Where retrieval earns its keep.

The strongest 2026 use cases share a shape: high-stakes questions over large, messy, access-controlled corpora — where a wrong answer has a cost and a citation is the difference.

Customer support copilots

Grounded answers over product docs, ticket history, and knowledge bases. 89% of RAG deployments target this; production systems report 70–90% hallucination reduction.

Internal knowledge search

Across SharePoint, Confluence, Slack, ticketing, and HRIS. Permission-aware retrieval as a first-class concern, not an integration afterthought.

Legal & contract Q&A

68% of legal departments now use RAG tools. Citations and audit trail are non-negotiable; we engineer for them from the first index.

Financial research & analyst assistance

Filings, reports, calls, internal models. Reasoning over evidence with full provenance — the analyst keeps their accountability.

Regulatory & compliance Q&A

Pharma, financial services, healthcare. Grounding directly against the controlling document, with citation to the clause that drove the answer.

Field-technician troubleshooting

Manuals, prior tickets, parts databases. Retrieval on the edge or in the field, offline-tolerant where the network won’t hold.

Frequently asked.

Is RAG still the right pattern in 2026, or has it been superseded?

Yes — but "RAG" now means something different. The 2024 retrieve-then-stuff pipeline is dead. Production RAG in 2026 is hybrid retrieval, multi-stage reranking, context engineering, and continuous evaluation. The pattern hasn’t been replaced; it’s been engineered.

When should we use GraphRAG versus standard hybrid retrieval?

Rarely — but decisively when it fits. GraphRAG earns its place when entities and relationships drive the answer: regulated finance, life sciences, complex B2B sales, legal. On most enterprise corpora, hybrid retrieval plus a good reranker beats a graph at a fraction of the build cost. We test before we recommend.

How do you evaluate a RAG system?

Faithfulness, answer relevance, context precision, context recall — measured continuously, not at launch. RAGAS or a custom harness, grounded in your real questions and your real failure modes. If you can’t show a regression dashboard on every release, the system isn’t production.

How do permissions and access controls work in retrieval?

Per-document, per-query, at index time and at retrieval time. Permission propagation from the source system into the index, with filters applied before reranking — never as a post-hoc redaction. If the user can’t see the document in SharePoint, the retriever should never have seen it either.

Do we own the retrieval system you build with us?

Yes. The code, the prompts, the chunking strategy, the eval harness, the integrations — all yours. We design every engagement so your team can operate, extend, and reindex independently. Enablement is built into the project, not sold as an upsell.

How long does an enterprise RAG project take?

A working production system in 8–14 weeks for a defined corpus and use case. The two-week Knowledge System Review tells you the realistic scope for your specific data, access model, and accuracy bar — before you commit to a build.

Where to start.

Knowledge System Review · 2 weeks · fixed fee

Bring us your RAG system — or your plan to build one.

We audit it against the five production criteria most teams skip — hybrid retrieval, multi-stage reranking, an evaluation harness, governance and permissions, and grounding integrity. You leave with a scored readiness assessment, a target architecture for your environment, and a staged delivery plan with effort estimates.

What you get: a production-readiness assessment scored against twelve criteria; a target retrieval architecture for your corpus, access model, and latency budget; a staged delivery plan with timelines and effort estimates; and one workshop with your engineering and data leads. Led by a senior consultant — fixed scope, fixed fee.

Ready to ship retrieval your operators actually trust?

A 30-minute conversation with a senior consultant. Bring a RAG system that’s stuck in pilot, or a corpus you’ve been told is “too messy to use.” We’ll tell you whether it’s ready to ship, where the gaps are, and what a Knowledge System Review would surface.
