RAG knowledge base for an enterprise services firm

Challenge

Knowledge lived in SharePoint, email and people's heads. New staff took months to become productive and senior staff were interrupted constantly.

What we built

• Ingestion of policies, playbooks, proposals and templates with permission metadata preserved.
• Hybrid (keyword + vector) retrieval and an LLM answer layer that always cites its sources and refuses when it cannot find one.
• Single sign-on and per-user access filtering, hosted in the client's Azure tenancy.
• Feedback buttons feeding an evaluation set that is re-scored on every content refresh.

Results

Internal survey and usage data showed roughly 70% faster resolution of common questions and a sharp drop in interruptions to subject-matter experts. Adoption crossed 60% of staff in the first three months.
