Your knowledge base, answerable in seconds.

For teams with institutional knowledge locked in docs, tickets, wikis, and databases. We build RAG pipelines that answer accurately, cite sources, know when to say 'I don't know,' and hold up at 3am.

our point of view

Most RAG systems fail not because of the LLM — but because of the retrieval.

The failure pattern is always the same: someone chunks documents naively, throws them in a vector store, and wonders why the system hallucinates or misses obvious answers. The LLM is fine. The retrieval is broken. We start with the retrieval.

We design retrieval pipelines with hybrid search (BM25 + vector), query rewriting, and re-ranking — because any single retrieval strategy has blind spots. We then build the evaluation harness before we write prompts: ground-truth question-answer pairs that tell us, objectively, whether the system is getting better or worse as we change it.

We also build the operational tooling: index drift monitoring, chunk freshness tracking, and cost-per-query dashboards. A RAG system that worked on day one and drifts silently by month three is not a working system — it's a liability you haven't discovered yet.

what we build

What we build.

01

Hybrid retrieval pipelines

BM25 + dense vector search with query rewriting, re-ranking (Cohere, cross-encoders), and metadata filtering — tuned to your retrieval precision goals.

02

Evaluation harnesses

200–2,000 ground-truth QA pairs covering factual recall, out-of-scope refusal, multi-hop reasoning, and citation accuracy. Regression tests on every change.

03

Document ingestion pipelines

Parsers for PDF, Word, HTML, Notion, Confluence, Google Docs, Slack, and Jira. Semantic chunking, metadata extraction, and freshness scheduling.

04

Citations & source attribution

Every answer surfaces the exact source chunks it drew from — with page numbers, document titles, and confidence scores. No black-box answers.

05

Access-aware retrieval

User-level and role-level document permissions enforced at retrieval time — so engineers can't pull HR documents and contractors can't read internal financials.

06

Index drift monitoring

Continuous recall and precision checks against your ground-truth set. Alerts when a new document batch or embedding model update degrades performance.

approach

How we build it.

01

Document audit

We review your knowledge base: format, quality, freshness, volume, and access model. We identify the top 50 questions users will ask and build a ground-truth eval set from them.

02

Chunking & indexing strategy

We test 3–4 chunking strategies (fixed, semantic, hierarchical) and measure recall against the eval set before choosing one. Chunk strategy is empirical, not a gut call.

03

Retrieval pipeline

We build the retrieval stack: embedding model, vector store, BM25, re-ranker, metadata filters, and query rewriter. We measure recall at every layer.

04

Generation & citation

We design the prompt, the citation format, the refusal behavior, and the out-of-scope handling. We run red-teaming to find hallucination patterns before launch.

05

Observability & tuning

We deploy with full query logging, relevance tracking, and cost monitoring. We improve weekly based on logged failures and user feedback.

We build a ground-truth eval set of 200–2,000 question-answer pairs before we start building. We measure recall, precision, answer faithfulness, and citation accuracy at every iteration. RAGAS metrics are tracked in a dashboard from day one.
