Knowledge Systems

Build Custom RAG Systems
with Fractional AI Teams.

Production-grade retrieval engines that unify unstructured vector databases, relational SQL tables, semantic knowledge graphs, and live APIs via Model Context Protocol (MCP). Fully deployable as sovereign AI in your private cloud.

Unified Context Architecture

The Four Dimensions of Enterprise Retrieval
engineered to work together.

Modern retrieval systems cannot rely on vector similarity alone. We build unified engines that dynamically query and cross-reference structured databases, semantic graphs, unstructured document embeddings, and live APIs.

Unstructured Vector Search

Retrieves semantic ideas, paragraphs, and general document concepts from unstructured content (PDFs, docs, emails). We optimize dense and sparse embedding alignments using late-interaction models for extreme precision.

Dense Embeddings Sparse Token Indexing Late-Interaction Models

Semantic Knowledge Graphs

Resolves entity relationships, hierarchies, ownership structures, and metadata dependencies. By mapping information into a network of nodes and edges, the engine performs multi-hop reasoning across scattered files.

Entity Extraction Relationship Traversal Multi-hop Query Routing

Structured SQL Engines

Executes high-accuracy data retrieval for numerical aggregates, dates, structured tables, and specific relational columns. The LLM translates user queries into database SELECT statements to bypass approximate search failures.

Text-to-SQL Pipelines Relational Schema Guardrails Exact Data Aggregations

Model Context Protocol

Bridges the model with real-time enterprise tools, SaaS platforms, local developer file workspaces, and live cloud environments. MCP provides standardized, secure, live API tool calling on-the-fly.

Standardized Tool Calls Live SaaS Integrations Secure Local/Cloud APIs
Naive vs Production RAG

Standard RAG breaks at scale.
We build systems that last.

Building a wrapper around an embedding API is easy. Building a system that stays accurate across millions of documents, different schemas, and real users is an engineering challenge.

The Naive Way

Vector-Only Incompleteness

Naive RAG relies solely on plain vector databases, leaving the model blind to relational database numbers, structured spreadsheets, semantic connection networks, and live external APIs.

Result: Hallucinated statistics, isolated retrieval, and stale data.
Our Production Stack

Unified Multi-Source Orchestration

We execute real-time parallel querying across vector stores (concepts), relational SQL (exact aggregates), semantic graphs (relations), and MCP connectors (live SaaS status).

Result: Complete 360° context & 100% data freshness.
The Naive Way

Unmonitored Latency

Chaining multiple vector database lookups and unoptimized LLM queries pushes response times over 3–5 seconds, ruining the application experience.

Result: Clunky, un-usable chatbots.
Our Production Stack

Sub-500ms End-to-End Latency

We optimize payload delivery, partition vector database indexes, configure smart key-value cache layers, and stream outputs to hit target response times under 500ms.

Result: Instant, interactive production responses.
The Naive Way

Flat Vector Lookup

Naive similarity searches look at pages or paragraphs in isolation, completely failing to trace relationships between entities, documents, or hierarchical topics.

Result: Multi-hop reasoning failure & missing contextual entities.
Our Production Stack

Knowledge Graph-Powered RAG

We structure your data into a semantic knowledge graph, mapping entities and relationships. Retrieval traces connections across different files for accurate multi-hop queries.

Result: Deep multi-document relationship matching and query tracing.
The Naive Way

Proprietary API Dependence

Routing all queries and private corporate files to third-party public APIs exposes sensitive metadata and proprietary intellectual property to external egress risks.

Result: Data privacy vulnerabilities & regulatory non-compliance.
Our Production Stack

Sovereign AI Deployment

We deploy the complete pipeline as a sovereign AI stack. Running open-weight models locally inside your secure cloud infrastructure guarantees that data never leaves your environment.

Result: Secure, isolated deployment with absolute compliance control.

Active Stage

1. Document Ingestion & Chunking

We design automated document ingestion pipelines that parse files (PDFs, docs, spreadsheets, slides) based on semantic structures rather than arbitrary character counts, preserving text formatting, tables, headers, and metadata.

Tactic: Layout-aware parsing, section-based chunking, metadata injection
The progression

Build a solid foundation.
Evolve to the frontier.

We meet you at your current maturity level and build a clear path forward — from foundational implementation to research-grade capability.

How It Works

How it works.
Simple, transparent, fast.

We bypass recruitment cycles to deploy fully operational, elite AI teams aligned directly with your engineering stack in days.

Step 01
Confidential

Submit a Project Description confidentially

Share your goals, scope, and timeline securely. We sign a mutual NDA immediately to safeguard your intellectual property, data access protocols, and trade secrets before any deep technical discussions begin.

Step 02
Architecture First

We discuss the architecture & team required

Our senior AI architects consult with your engineering leaders. Together, we outline the model choices (LLMs, custom SLMs, RAG structures), data pipeline requirements, infrastructure constraints, and determine the exact technical skillsets required for your team.

Step 03
Vetted Match

Find, vet, and allocate your custom team

We match your blueprint with domain specialists from our vetted network. We pull together engineers with direct experience in voice agents, vector embeddings, fine-tuning, or specific MLOps pipelines. We assemble your custom team in days, not months.

Step 04
Senior Managed

We deploy the team and assign a senior PM

Your fractional AI team embeds directly into your workflow (Slack, GitHub, Jira). We assign a Senior PM to lead sprints, host cadence calls, manage deliverables, and ensure frictionless communication, giving you direct R&D execution without management overhead.

Step 05
100% IP Ownership

You own the code, IP, and capability

Every single line of code, custom model weights, architectural schema, database indexing script, and documentation stays in your repositories. You own all IP from day one, and we provide clean handovers so your internal team can scale the solution permanently.
