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.

Customer stories

“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.”

Read the story

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

“We’re still a team of three, but we’re often doing far more than the equivalent of three full-time employees. That’s down to how we're able to leverage systems, data, and processes.”

Michael HowesHead of Data & Insights at Dishoom
