Architecture

A data platform your agents can operate

Move data into your warehouse, build SQL models in GitHub or connect dbt, and sync results back to your tools. Run high-performance pipelines with CDC streaming, tests, and retries. Work in Weld, automate through the API, or delegate workflows to your agents through MCP.

Use Weld for ingestion, transformation, orchestration, or reverse ETL. Run the components together or combine them with your existing warehouse, modeling framework, and development tools.

Data Pipelines

Incremental, full and CDC replication from 300+ sources. Schema-aware, type-safe, and reliable by default.

Customer stories

“Weld is just the first building block in our AI vision. We need to ingest the data, we need a single source of truth, we need metrics defined, and in order to do that, we need a data platform.”

Read the story

Laurenz BrockmeyerDirector of Data & Analytics at OMHU

“Weld gives us the ability to see a huge array of KPIs and data points that we can then feed back to clients in an insightful and actionable way.”

Pritesh PatelHead of Data and BI at eComplete

“One of the biggest impacts has been unlocking new ways to buy media. Before, we didn’t have the data to back up strategic decisions – now we do.”

Jacob PoulsenHead of Marketing Expansion at Flatpay

“Before Weld, we had to rely on custom Python scripts and manual processes that were time-consuming and error-prone.”

Rodrigo Andres ValleData Engineer at Holafly
