Why pay for what's open source?

Because wiring auth, audit, queue, connectors, and a multi-tenant data plane around a Python package takes weeks you don't have.

Hosted infrastructure

No Postgres to provision, no Arq queue to wire, no auth to roll. Sign up and run.

Multi-tenant orgs

Clerk-backed organizations, plan-aware quotas, role-scoped access. Built in.

Cryptographic audit

Append-only audit_log with per-org SHA-256 chain. Verify the trail end-to-end.

Source connectors

22 connectors live: Postgres, Salesforce, HubSpot, S3, BigQuery, Snowflake, and more.

Review queues

Ambiguous matches surface to stewards. Approve, split, or merge with full lineage.

No vendor lock-in

Engine is OSS. If we go away, you keep running. Try that with Reltio.

The workbench

Event-sourced notebooks. Every tool call is a step you can replay, fork, rewind, or audit.

The workbench: a completed goldenmatch.dedupe run, with the event log, result metrics, issue queue, preview pane, and assistant chat panel all visible

Three use cases we're shipping for now

Resolve customer data in minutes.

Free tier includes 3 sources, the workbench, and a demo project ready to run.
