Weld

Weld is a managed data movement platform that moves data from business tools and databases into a warehouse, models it with SQL, and syncs results back out to operational tools. It is positioned as a data platform that AI agents can operate as well as people, with a REST API and a Model Context Protocol server that lets assistants such as Claude, ChatGPT and Cursor create syncs, add streams and trigger runs. The platform covers extraction, transformation, orchestration and activation. Extraction includes ELT syncs, change data capture streaming, schema drift handling, backfills and custom API connectors. Transformation uses SQL models with Git sync, dbt, Cube, lineage, tests and an AI assisted SQL editor. Orchestration offers schedules, dependencies, retries and run history. Reverse ETL, BI sync, webhooks and alerts send data onward. Sources include Shopify, HubSpot, Salesforce, Stripe, Postgres, MySQL, MongoDB and Google Sheets. Destinations include BigQuery, Snowflake, Databricks, Redshift, ClickHouse and Postgres. It suits data and analytics teams that want pipelines run with little manual work. Pricing is based on monthly active rows. Basic starts at $99 per month billed annually, with 5M rows, two connectors, one seat and daily syncs. Premium starts at $389 per month with six connectors, three seats, hourly syncs, dbt, orchestration and the MCP server. Business starts at $959 per month with ten connectors, five seats and 15 minute syncs. Enterprise is priced on request and adds 5 minute syncs, change data capture and a choice of cloud. A free start is offered.
