# Lakehouse42

> Enterprise knowledge platform with three-way hybrid retrieval achieving 91% recall accuracy.

Lakehouse42 is an LSR-as-a-Service (Lakehouse-Streamhouse-Realtime) platform for enterprise companies. Think of it as Databricks/Snowflake for unstructured data. Enterprises can ingest any data (documents, audio, video, images, structured data), and the platform automatically extracts knowledge, builds searchable indexes, and enables real-time querying across all data types.

## Core Capabilities

- **Hybrid Retrieval**: Combines dense vector search, sparse vector search, and BM25 with Reciprocal Rank Fusion for 91% recall accuracy
- **Sub-50ms Response Time**: Search results returned in under 50 milliseconds
- **Multi-modal Ingestion**: Supports PDF, DOCX, Excel, PowerPoint, plain text, markdown, audio, video, images, and structured data
- **100+ Languages**: Ask questions in one language and find documents in another without translation
- **Knowledge Graph**: Automatic entity extraction and relationship mapping
- **AI Assistants**: Configurable AI assistants powered by your organization's knowledge base
- **Enterprise Security**: SOC 2 Type II Ready, GDPR compliant, HIPAA ready, complete tenant isolation, SSO support
- **BYO Infrastructure**: Bring your own storage (S3, GCS, Azure), catalog, compute, and LLM providers

## Architecture

The LSR architecture provides three processing tiers:
- **Realtime Layer** (ClickHouse): Hot data, sub-second OLAP queries (<100ms)
- **Streamhouse Layer** (Arrow micro-batch): Incremental processing, agentic operations (100ms-1s)
- **Lakehouse Layer** (Apache Iceberg v3 + Polaris): Source of truth, historical data (1-10s)

Data automatically flows between tiers based on access patterns.

## Plans

- **Free**: 100 documents, 1,000 queries/month, 1 user
- **Starter**: Increased limits, team collaboration
- **Professional**: Advanced analytics, custom integrations
- **Enterprise**: Unlimited everything, SSO, dedicated support, SLAs
- **Self-hosted**: Run in your own infrastructure
