Enterprise Challenges

Challenges We Solve

Naive Chunking Destroys Retrieval Quality

Fixed-size chunking splits context mid-thought, so retrieval returns fragments that are technically relevant but semantically incomplete, degrading answer quality even when the model itself is capable.

Embedding Model Mismatch With Domain Vocabulary

General-purpose embedding models underperform on domain-specific terminology in legal, clinical, or engineering documents, missing relevant content that doesn't share surface-level vocabulary with the query.

Hallucination Under Ambiguous or Missing Context

LLMs confidently generate plausible-sounding but incorrect answers when retrieval returns weak or no relevant context, absent an explicit mechanism to abstain rather than guess.

Stale or Unsynchronised Knowledge Bases

Vector indexes fall out of sync with source systems, causing the LLM to ground answers in outdated policies, pricing, or documentation without any signal that the content has changed.

Retrieval Latency at Enterprise Document Scale

Naive vector search across millions of documents introduces latency that breaks real-time chat experiences without deliberate indexing and infrastructure design.

No Way to Measure or Improve Answer Grounding

Without retrieval evaluation metrics and citation tracing, teams can't tell whether a wrong answer came from bad retrieval or bad generation, so the underlying problem never gets fixed.

What We Deliver

Core Capabilities

01

Chunking Strategy Design

Semantic, recursive, and structure-aware chunking tuned by document type, preserving context boundaries instead of splitting on arbitrary character counts.

02

Embedding Pipeline Engineering

Domain-tuned embedding model selection and fine-tuning so retrieval understands your specific vocabulary rather than general web text.

03

Vector Database Architecture

Production architecture across Pinecone, Weaviate, Milvus, pgvector, and Elasticsearch, selected for your scale, latency, and data residency requirements.

04

Hybrid Search and Reranking

BM25 and dense vector fusion with cross-encoder reranking, consistently outperforming vector-only retrieval on precision at the top ranks that matter.

05

Grounding and Citation Tracing

Source attribution, confidence scoring, and abstention logic so the system says 'I don't know' instead of fabricating an answer when retrieval is weak.

06

Incremental Index Synchronisation

Real-time or scheduled synchronisation with source systems so the knowledge base never silently drifts out of date.

07

Retrieval Evaluation Frameworks

Precision@k, recall, and groundedness scoring with human evaluation loops, giving teams a measurable way to improve retrieval quality over time.

08

Multi-Modal and Structured Data Retrieval

Retrieval spanning text, tables, diagrams, and structured records, so answers grounded in a spec sheet or contract clause are as reliable as those grounded in prose.

Enterprise Use Cases

In Production

Investment Research Analyst Assistant

Challenge

Asset manager's research analysts spending 14 hours weekly manually searching across 40,000+ internal research notes and filings to answer client questions, with no reliable full-text search.

Solution

RAG system combining semantic chunking of research notes, a domain-tuned embedding model, hybrid BM25/vector search, and citation-traced answers surfaced directly in the analyst's existing workflow tool.

Outcome

Analyst research time reduced 68%. Retrieval precision@5 measured at 93%. Zero citation-traceability failures across 18 months in production.

Healthcare Clinical Policy Grounding

Challenge

Hospital system's clinical staff calling a help desk an average of 900 times monthly for questions answerable from 3,000+ pages of clinical protocol documents that were poorly indexed.

Solution

RAG system with structure-aware chunking preserving protocol hierarchy, a clinically tuned embedding model, and an abstention mechanism preventing answers when retrieval confidence fell below threshold.

Outcome

Help desk call volume reduced 71%. Zero instances of ungrounded clinical guidance reaching staff during the pilot audit period.

Financial Compliance Policy Search

Challenge

Bank's compliance team manually cross-referencing regulatory changes against 12,000 pages of internal policy documents, taking an average of three days per regulatory change to assess impact.

Solution

RAG pipeline ingesting policy documents and regulatory bulletins with recursive chunking, incremental index sync on document updates, and a reranking layer prioritising the most current policy version.

Outcome

Regulatory impact assessment time reduced from three days to four hours. Index sync latency reduced to under 15 minutes from document update.

Manufacturing Engineering Documentation Retrieval

Challenge

Industrial equipment manufacturer's field engineers unable to quickly locate answers across 25,000 pages of technical manuals spanning 40 product lines, extending average repair time.

Solution

Multi-modal RAG system retrieving from text, diagrams, and tabular spec sheets, with structure-aware chunking preserving manual section hierarchy and citation links back to exact manual pages.

Outcome

Average field repair diagnosis time reduced 39%. Engineer satisfaction with documentation search improved from 2.1 to 4.4 out of 5.

Healthcare Payer Provider Contract Q&A

Challenge

Health insurer's provider relations team manually searching thousands of provider contracts to answer reimbursement rate questions, with a 48-hour average turnaround.

Solution

RAG system over contract documents with clause-level chunking, hybrid search, and confidence-scored answers with direct citation to contract clause and page.

Outcome

Turnaround reduced to under two hours. 96% of answers correctly cited to source clause in quality audit sampling.

Digital Bank Internal Policy Assistant

Challenge

Digital bank's onboarding operations team manually referencing KYC/AML policy documents for edge-case account approvals, creating inconsistent decisions across 200+ reviewers.

Solution

Internal RAG assistant grounding policy answers in the current KYC/AML policy set with recursive chunking and version-aware retrieval, deployed as an internal operations tool rather than a customer-facing feature.

Outcome

Decision consistency across reviewers improved from 74% to 96% inter-rater agreement. Policy lookup time reduced 82%.

Industry Applications

FAQ

Common Questions

RAG retrieves relevant content from your knowledge base at query time and feeds it to the LLM as context, rather than baking knowledge into model weights. It's faster to update, easier to audit via citations, and usually cheaper than fine-tuning for knowledge-grounding use cases.

Selection depends on scale and requirements — Pinecone or Weaviate for managed simplicity, Milvus for very large self-hosted deployments, and pgvector when the client wants to keep vectors inside an existing Postgres environment.

Development typically ranges from $70,000 to $250,000 depending on corpus size and integration complexity. Ongoing inference and vector database hosting costs scale with query volume and are modelled during the discovery phase.

Most systems reach production in 8–14 weeks, covering chunking design, embedding selection, retrieval architecture, and evaluation against your defined precision targets.

We benchmark groundedness against a held-out evaluation set before launch, then track it in production. Reduction comes primarily from better chunking, hybrid retrieval, reranking, and abstention logic rather than the LLM itself.

Yes. Self-hosted vector databases such as Milvus or pgvector run entirely within your infrastructure for organisations with data residency or air-gapped requirements.

We build incremental sync pipelines triggered on document updates, typically achieving sub-15-minute index freshness rather than relying on periodic full reindexing.

RAG is the retrieval-and-grounding architecture underneath a system — it's often a component inside a chatbot or agent, not a customer-facing product itself. We build RAG standalone for internal knowledge tools, or as the grounding layer inside a chatbot or agent engagement.

If you already know RAG is the right fit (grounding answers in your own documents/data), we scope and build directly. If you're unsure whether RAG, fine-tuning, or a simpler approach fits best, a short consulting engagement resolves that first.

RAG systems need index freshness monitoring as your source documents change, periodic retrieval-quality evaluation, and cost tracking as usage scales. We offer this as a scoped monitoring retainer rather than assuming a 'build and forget' handoff.

Yes — startup engagements are typically a single knowledge base grounding one product surface; enterprise engagements add access-tiered retrieval across multiple document stores and departments.
