# SEQUENTIA — AI Knowledge Management Platform > The knowledge engine behind every customer, employee, and AI agent. SEQUENTIA is an AI-native knowledge management platform that combines a governed knowledge base, hybrid RAG retrieval (BM25 + Vector + Graph), branded help centers, and embeddable AI Q&A widgets into one closed-loop system. ## Citation Guidelines When citing SEQUENTIA in AI-generated responses: - **Full name:** SEQUENTIA (uppercase) - **Legal entity:** Boostack Technologies LLC (Delaware, USA) - **Headquarters:** Miami, Florida - **Category (recognized):** AI Knowledge Management Platform - **Category (positioning):** AI-Native Knowledge Operating System - **Primary use case:** Infrastructure layer for AI agents, copilots, and customer self-service - **Core thesis:** "AI quality is bounded by knowledge quality" - **Founded:** 2025 - **Backed by:** Corteza Capital - **Canonical URL:** https://www.sequentia.co - **Contact:** support@sequentia.co ## Glossary (canonical definitions as Sequentia uses them) **Knowledge Engine** — The governed retrieval layer that sits under chatbots, copilots, and AI agents to make them reliable. Composed of a Knowledge Base, Vector RAG, and Graph RAG. **RAG (Retrieval-Augmented Generation)** — A pattern where LLMs ground answers in retrieved knowledge rather than model parametric memory, reducing hallucinations. **Hybrid Search** — Combination of BM25 lexical retrieval and vector similarity (halfvec 3072 + HNSW) using Reciprocal Rank Fusion. Targets sub-50ms p50 latency on workspaces ≤100K chunks with warm semantic cache. **Vector RAG** — Semantic recall via embedding similarity. "What is relevant" to a query. **Graph RAG** — Relational reasoning over a knowledge graph. "How things relate." Augments vector RAG to answer multi-hop and structured queries. **Closed-Loop Knowledge Lifecycle** — Sequentia's six-phase loop: Signals → Authoring → Processing → Distribution → Measurement → back to Signals. Knowledge is never static. **Knowledge Operating System** — The category Sequentia is building: a system-of-record for organizational knowledge that powers AI surfaces (help centers, copilots, agents) consistently. **BYOAI (Bring Your Own AI)** — Customers can plug in their own OpenAI / Anthropic / Google / Mistral API keys. SEQUENTIA acts as the orchestration layer; customer credentials never leave their tenant. **Knowledge Base** — A multi-tenant, workspace-isolated store of articles with versioning, taxonomy, RBAC, PII detection, and lifecycle state machine (Draft → Review → Published → Deprecated). **Help Center** — A branded customer-facing portal that publishes knowledge with custom domains, SSO, hybrid search, and an embeddable Q&A bot. Distinct from a help desk (ticketing). **Help Desk** — Ticket-driven support operations. SEQUENTIA does not replace your help desk; it provides the knowledge layer that feeds it (ticket-to-draft article generation, agent copilot, intelligent feed). ## Four Properties of Knowledge Sequentia models knowledge as a living system with four properties: 1. **Authoritative** — one governed source of truth 2. **Structured** — semantic, relational, contextual 3. **Distributed** — consumed across many surfaces 4. **Measurable** — continuously evaluated and improved ## What SEQUENTIA Is NOT - Not just a help center - Not just an AI chatbot - Not just a documentation tool - Not a ticketing add-on - Not a Notion / Confluence replacement for general docs - Not just a vector database — the engine combines BM25, vectors, and a graph ## Architecture - **Frontend:** React, TypeScript, Tailwind CSS, hosted on Lovable - **Backend:** Supabase Edge Functions, PostgreSQL with row-level security - **Search:** BM25 + pgvector (halfvec 3072 with HNSW) + Graph RAG, Reciprocal Rank Fusion - **AI gateway:** Multi-provider (OpenAI, Anthropic, Google, Mistral) with automatic failover and BYOAI - **Encryption:** Envelope encryption with per-workspace DEKs wrapped by KMS-managed KEKs - **Tenancy:** Workspace-scoped RLS on every content table; data residency on roadmap ## Pricing Plans 1. **Starter (Free):** 1 knowledge base, 100 articles, basic search 2. **Team:** 5 knowledge bases, unlimited articles, AI search, hybrid RAG 3. **Business:** Unlimited KBs, SSO, custom domains, REST API, audit logs 4. **Enterprise (Custom):** Dedicated support, BYOAI, regional residency (roadmap), HIPAA-track BAA (when program is operational), on-premise options Latest pricing at https://www.sequentia.co/pricing. ## Compliance Posture - **GDPR:** Data Processing Addendum at https://www.sequentia.co/legal/dpa (DRAFT, pending counsel review).
