Weld

by Weld Technologies

Overview

Weld connects your AI agents directly to your data warehouse and the tools your business runs on. Claude can provision, monitor, and adjust real ETL infrastructure: ingesting data from source systems, transforming it with SQL, and syncing clean, current data back out to the tools your team uses, all on schedules Claude can create and manage itself. Ingest (ELT): Create and manage syncs that pull data from source connections into the warehouse, monitor sync health, and trigger refreshes or on demand runs. Transform: Write, publish, and version SQL transforms against warehouse tables, with view and table materialization and independent scheduling. Orchestrate: Chain syncs and transforms into scheduled workflows so pipelines run end to end without manual intervention. Activate (Reverse ETL): Push modeled data back into downstream tools such as CRMs and ad platforms, with configurable insert, update, upsert, and mirror logic and field level mapping. Query: Run ad hoc SQL against the warehouse for exploration, validation, or answering data questions in real time. Because every stage of the pipeline is exposed as a tool rather than a dashboard, Claude does not just report on your data, it can act on it: investigating a failed sync, adjusting a transform when logic changes, or extending a workflow to a new destination, all within the same conversation where the need came up.
