We are the team behind DuckDB

We design, build, and maintain the DuckDB engine — and help companies run it reliably in production through enterprise support, advisory, and engineering collaboration.

Our story

DuckDB began as a research project by Hannes Mühleisen and Mark Raasveldt at CWI in Amsterdam. They set out to build a simple, fast, embeddable analytical database that removes the complexity of traditional client–server systems while still offering powerful SQL and high-performance analytics.

What started as a research prototype quickly grew into a widely adopted open-source project used across data science, engineering, and analytics teams worldwide. DuckDB Labs was created to support this growth — providing a dedicated team to develop the engine and help companies use it effectively in production.

Today, DuckDB Labs remains independent and fully owned by the original creators. We've deliberately chosen not to take venture capital, so we can focus on sustainable engineering, correctness, and keeping DuckDB open and MIT-licensed for everyone.

Who we are

We are the core development team behind DuckDB, the in-process analytical database built for simplicity, portability, and speed. Based in Amsterdam, our team of more than 20 engineers and researchers maintains the open-source project, guides the architecture, designs new features, and stewards the long-term roadmap of DuckDB and DuckLake.

Our work spans all layers of the system: query planning, vectorized execution, storage formats, extensions, data lake integration, language bindings, and performance optimization.

Alongside our engineering work, we collaborate closely with the community and with the DuckDB Foundation — the independent non-profit that safeguards DuckDB’s intellectual property and ensures that DuckDB remains open-source under the MIT license in perpetuity.

We combine deep database systems expertise with a commitment to openness, clean design, and long-term maintainability.
