# Reactor

> Reactor is the intelligent data platform. It preserves your raw history, resolves shared meaning across every source, and ships trusted data products to your warehouse — no army of engineers, no months of pipeline building. Reactor was acquired by Stelao in 2026 and is now operated by the Stelao team.

## What Reactor does

- Connects to 100+ commerce, marketing, ads, support, and fulfillment systems plus modern data warehouses (Snowflake, BigQuery, Databricks, AWS, Apache Iceberg) and AI vector stores (Pinecone, Weaviate, Chroma, Qdrant, Milvus, pgvector).
- Preserves every raw record immutably from day one, so historical data can be remapped and reprocessed for new use cases without re-ingesting from source ("data replay").
- Resolves identity across messy sources — define your shared entities once, and Reactor applies those definitions at ingest so the same customer, order, or product looks identical everywhere.
- Ships versioned, governed data products directly to your warehouse — you own the data and the storage.
- Exposes those data products to Claude and other MCP-compatible AI agents via the Reactor MCP connector, so assistants can query versioned, lineage-tracked data instead of guessing across raw source systems.
- Includes Electron AI, an agentic teammate that writes mappings, suggests joins, and tags data automatically.

## Who Reactor is for

- Data teams at modern brands who need governed data products fast — not just raw rows piped into a warehouse.
- Analytics, AI, and activation teams that want to skip months of pipeline building and start delivering value in week one.
- Engineering leaders looking to consolidate Fivetran + Matillion + downstream modeling tools into a single low-code platform.

## Key differentiators

- Preserves raw history: every record logged immutably, so you can remap and replay data for new use cases without ever re-ingesting from source. Most pipeline tools structurally cannot do this.
- Resolves identity at ingest: define shared entities once, Reactor applies them across every source as data lands. Fivetran and Matillion stop at moving raw data.
- Ships data products, not raw tables: versioned, governed outputs with lineage tracking that downstream analytics, AI, and activation can trust.
- Trust layer for AI agents: the Reactor MCP connector gives Claude and other MCP-compatible agents safe, structured, lineage-aware access to governed data products. The agent is the interface; Reactor is the trustworthy data substrate the agent reasons on.
- Low-code, analyst-friendly interface — drag and drop with Excel-like expressions.
- Hours to first data product, not months of pipeline building.
- Warehouse-native: data lands in Snowflake, BigQuery, Databricks, AWS, or Iceberg. Reactor is the pipeline, not another silo.
