RAG / Vector Database Implementation
RAG isn't "embed and pray." Retrieval quality is the whole game. We engineer RAG systems that pull the right context, ground every answer, and prove their accuracy with evaluation — not hope.

Your Data Is Trapped. Generic AI Is a Liability.
Your most valuable knowledge sits in documents, tickets, and contracts a generic LLM can't see — and bolt one on carelessly and it invents answers or retrieves the wrong passage with total confidence. A demo that works on three clean PDFs is not a system that works on a hundred thousand messy ones. We build RAG the way production demands: real ingestion for complex documents, a deliberate chunking and embedding strategy, the right vector database, hybrid search with reranking, and grounding with citations — then we measure retrieval quality and answer accuracy. Embedding is easy; retrieval quality is the asset.
The Numbers Behind Our Engineering
What We Engineer in RAG & Vector DB
RAG readiness and data assessment
What's retrievable, what's missing, what it'll take.
Ingestion and ETL pipelines
Complex PDFs, tables, images, and structured sources.
Chunking and embedding strategy
Tuned for your content, not a generic default.
Vector database selection and architecture
Pinecone, Weaviate, Milvus, or pgvector, chosen on merit.
Hybrid and semantic search with reranking
Precision retrieval, not keyword luck.
Grounding, citations, and guardrails
Verifiable answers, controlled behavior.
Evaluation and hallucination monitoring
The asset that proves the system is accurate.
Private and self-hosted LLM deployment
Keep sensitive data in your environment.
Agentic and multi-modal RAG
Tool use, multi-step reasoning, and image/document inputs.
How We Deliver
Assess — review your content, use case, and accuracy and security requirements.
Architect — design the ingestion, embedding, vector store, and retrieval strategy.
Build — implement the pipeline, search, grounding, and guardrails.
Evaluate — measure retrieval quality and answer accuracy; tune until it holds.
Deploy and operate — ship securely, then monitor for drift and hallucination.

Frequently Asked Questions
How much does a RAG implementation cost?
It depends on data complexity, volume, and security needs. A focused knowledge assistant is far smaller than an enterprise, multi-source system. We scope and price up front, with no open-ended billing.
How long does it take to build?
A focused RAG system typically reaches a working, evaluated state in weeks; complex or multi-source builds are phased so you see value early.
Should we use RAG or fine-tune a model?
RAG is usually the better first move when answers must reflect your current, proprietary knowledge — faster, cheaper, and easy to keep updated. Fine-tuning suits consistent style or behavior. Often the best system uses both, and we advise honestly.
Can we keep our data private and self-hosted?
Yes. We support private and self-hosted LLM and vector-store deployments so sensitive data never leaves your environment.
Do we own the embeddings, pipelines, and IP?
Completely. All data, embeddings, and IP are yours on delivery.
