Data should feel inevitable.
We built Reactor to end the era of brittle pipelines and engineer-only data stacks. Modern teams deserve clean, modeled data on day one.
Our story
Built by teams who've shipped the hard part.
Reactor started inside SoundCommerce, where we spent years wiring up commerce data for some of the most demanding retail brands on the planet. Every engagement told us the same story: the modern data stack moves data brilliantly and stops short of making it useful.
Pipelines took quarters to build. Semantic layers were always somebody else's problem. AI and analytics teams sat downstream waiting for clean tables that never quite arrived in the shape they needed.
Reactor is the answer we wished we had: an intelligent data platform that connects, models, and lands governed data products directly in your warehouse. No army of engineers. No re-ingestion. No re-platforming when the question changes.
In 2026, Reactor was acquired by Stelao. The platform is now operated by the Stelao team, with the same focus on shipping clean, modeled data and the resources to take it further.

What we believe
The way we think about data.
Four convictions that shape every product decision and every customer engagement.
Make data useful
Useful, not just moved.
Most tools stop at moving raw rows. We model, label, and shape data into governed data products, ready the moment they land in your warehouse.
Accessible to everyone
No engineering degree required.
Analysts ship pipelines. Ops teams connect sources. Visual, low-code tooling means the people closest to the work own the data.
Own your data
Your warehouse, your data.
Reactor is the pipeline, not another silo. Data lands in Snowflake, BigQuery, Databricks, or AWS, fully owned by you.
Replay-ready by default
Build for tomorrow's questions.
Every record is immutably logged. When the question changes, you remap and reprocess. No re-ingestion, no lost history.
How we work
Operating
principles.
Internal commitments that show up in product decisions, customer engagements, and the kind of company we're building.
Hours, not months.
Speed-to-value is the product. If you're still building plumbing six months in, we failed.
Open by default.
Your data, your destinations, your governance. We integrate with your stack, never replace it.
Built for change.
Data needs evolve. Immutable raw logging and data replay mean today's pipeline is ready for tomorrow's question.
Hand the keys to the team.
Engineers don't need to be the bottleneck. Analysts, ops, and product own the pipelines closest to their work.
From SoundCommerce to Stelao.
Reactor was born inside SoundCommerce building commerce data products for some of the world's most demanding retail brands. Battle-tested at enterprise scale, then spun out as its own product, and now part of Stelao.
The platform that shipped modeled data for SoundCommerce customers ships data for yours.
