About Lagrange Labs
Lagrange Labs is a product studio. Our roots are in data engineering: pipelines, warehouses, the plumbing that makes numbers trustworthy. We build full-stack products on top of that. Recently we've shipped a camp-operations platform that 144 families use daily, an AI storybook creator on the App Store, and LineagePro, the free SQL lineage tool you can use on this site.
We're a small, senior studio: a hands-on lead backed by a trusted bench of engineers (family and longtime collaborators) we bring in as a project needs them. That keeps us close to the code and lets us scale up when the work calls for it.
We stay on after launch. That means App Store reviews, push-notification quiet hours, payment reconciliation, and the 7am bug report fixed before lunch. Owning products that far out changes how you build them in the first place, and that discipline carries into every client engagement.
Three of the products we run today. Each links to its case study.

About LineagePro
LineagePro is a free SQL column-level lineage visualizer. Paste any multi-statement SQL pipeline and instantly see how data flows from source tables through intermediate transformations to target tables. It supports Oracle, MySQL, PostgreSQL, and Snowflake dialects, powered by SQLGlot. We built it as a free community tool because understanding how data flows through SQL pipelines shouldn't require an enterprise contract.
