dbt Labs

dbt Labs makes dbt (data build tool), which became the industry standard for the transformation step of the modern data stack — the "T" in ELT. dbt lets data engineers and analysts define transformations as version-controlled SQL models with built-in testing and documentation, bringing software-engineering discipline to analytics. Its AI layer, dbt Copilot, generates models, tests, and documentation from natural language. In 2025 dbt Labs combined with the data-integration company Fivetran, pairing data movement with transformation in one company.
