Weld in Short
Weld is a data pipeline and activation platform built for teams that need reliable ingestion, dbt-powered transformations, and data for AI agents and applications. Its Connect API gives agents and applications programmatic access to data pipelines. With 300+ in-house-built connectors, first-class dbt Core and dbt Cloud support, and near real-time syncs, Weld lets teams move data from any source into their cloud data warehouse and activate it back into business tools.
What Weld does well
- Agent-native platform with Connect API for programmatic access
- First-class dbt Core and dbt Cloud integration

Weld’s graphical interface is intuitive and easy to work with, even for teams with limited SQL experience. Its flexibility across sources—from databases to Google Sheets and APIs—made onboarding smooth, and performance across larger workloads was consistently strong. Support was responsive and helpful throughout our setup and ongoing use.
