No vector DB vendor
The Problem
Enterprise knowledge is locked in documents that AI cannot access reliably
Most RAG implementations use simple vector search that misses exact matches. They cannot cite sources reliably. They cannot run on-premise. They cannot isolate data between departments. They fail compliance audits. Governments and regulated enterprises cannot deploy them.
Our Approach
Hybrid retrieval on PostgreSQL — no proprietary vector database
- ◆Hybrid retrieval: BM25 (ParadeDB) + pgvector semantic + Apache AGE graph — all on PostgreSQL
- ◆RRF fusion (k=60) with reranking — combines keyword, semantic, and graph signals
- ◆Jina v4 asymmetric embeddings — separate query and passage LoRA adapters
- ◆Every answer includes citations to source documents — auditable, verifiable, defensible
- ◆Multi-tenant with PostgreSQL RLS — complete data isolation between departments and clients
- ◆Langfuse observability — full query audit trail, latency monitoring, answer quality tracking
- ◆On-premise deployment — data never leaves your servers, CISO-approvable architecture
Production Proof
| Metric | Before | After |
|---|---|---|
| Deployment model | Cloud-only (Pinecone, Weaviate) | On-premise or cloud |
| Answer citations | None or unreliable | 100% — every answer cites source |
| Vector DB vendor | Pinecone/Weaviate dependency | PostgreSQL — no new vendor |
| Multi-tenancy | Shared index (data leakage risk) | RLS-enforced isolation |
| Audit capability | No query audit trail | Full Langfuse audit log |
| Active deployment | N/A | Government IGST evaluation — active |
