From Six Hours to Seconds: Enterprise RAG for a Leading International Tax Advisory Firm

Client identity withheld at their request — results independently verified by Sphere.

SOLUTION

A production enterprise RAG system with hybrid vector + keyword retrieval, jurisdiction-aware metadata filtering, role-based access control, and a tamper-evident audit trail — live in 5 weeks, built with Sphere's Precision-Driven Engineering™ methodology.

Frequently Asked Questions

Retrieval-Augmented Generation grounds AI answers in your actual documents and data, with citations — instead of relying on a model's general training, which can be outdated or simply wrong for your specific business context.
Our fastest verified production deployment took 5 weeks from kickoff, using our Precision-Driven Engineering™ methodology. Typical enterprise builds run 6–8 weeks depending on data complexity and integration scope.
In your own cloud environment — AWS, Azure, or GCP. Sphere does not require your data to leave your infrastructure.
Yes. Sphere builds RAG with role-based access control, audit-grade logging, and architectures aligned to GDPR, HIPAA, and SOX from the design stage — not added after launch. Our tax-advisory case study includes a tamper-evident audit trail built in from day one, the same pattern we apply for healthcare and financial services clients.
No — Sphere works across OpenAI GPT, Claude, Mistral, Llama 3, Gemini and Mixtral, and across Pinecone, Weaviate, FAISS, Milvus, Chroma and Elastic, so you can swap components as the AI landscape evolves.
Both are possible. Some clients want ground-up enterprise AI development and a new knowledge base AI for enterprise; others want their existing enterprise search tools and knowledge management AI kept in place, with RAG added as a layer on top. Sphere scopes an enterprise RAG implementation around what you already run, not a forced rebuild.
A generic LLM answers from general training data and can hallucinate specifics about your business. RAG grounds every answer in your real, current documents, with a citation trail your team can verify.
