Amazon has signed a definitive agreement to acquire DuckLabs, the Amsterdam-based development company behind DuckDB. The transaction is expected to close in early September 2026, subject to customary closing conditions, and the parties have not disclosed the financial terms.

The key distinction is that AWS is acquiring the company and its team—not taking ownership of DuckDB, DuckLake, or Quack. Those projects are expected to remain free and open source under their existing MIT licenses, with the independent nonprofit DuckDB Foundation continuing to steward them. 2
What AWS is acquiring
When the transaction closes, DuckLabs’ team will join Amazon Web Services and remain based in Amsterdam. Co-founders Hannes Mühleisen and Mark Raasveldt, who created DuckDB and co-founded DuckLabs, are expected to continue leading the team and the project’s technical direction within AWS. 
DuckLabs was established as a bootstrapped, founder- and employee-owned home for the DuckDB development team. It grew to more than 30 people in Amsterdam through support and feature-development partnerships rather than venture funding.
That structure makes the transaction primarily an acquisition of engineering capability and people. The open-source projects themselves are not being folded into a proprietary AWS product, according to the companies’ announcement.
What stays the same for DuckDB users
AWS and DuckLabs say users should see no immediate changes. The DuckDB team will continue contributing to the project from Amsterdam, while DuckDB, DuckLake, Quack, and other open-source components remain under the Foundation’s oversight and their MIT licensing. 2
That means the announced deal does not, by itself, change DuckDB’s licensing model or make the core project an AWS-only product. The longer-term effects will depend on how AWS and the Foundation define their plans after closing; those details have not yet been fully specified.
AWS and DuckLabs were already working together
The acquisition builds on an existing relationship rather than starting a new one. AWS says the companies have worked together since 2024. Their collaboration has included support for Amazon S3 Tables and Amazon SageMaker Lakehouse, including work intended to provide first-class S3 Tables support in DuckDB. 8
Bringing the team into AWS formalizes that collaboration and gives the company a direct way to apply DuckLabs’ database-engineering expertise across AWS data products. AWS says the goal is to make its analytics services faster, simpler, and more cost-effective for customers. 9
Why DuckDB is strategically important
DuckDB is an embedded analytical database, meaning it runs in-process with an application rather than requiring users to operate a separate database server. That design makes it portable and useful inside developer tools, data products, and other applications that need analytical processing close to the data. 8
The project has also developed significant developer adoption. DuckLabs reports more than one million downloads per day, a level of use that helps explain why AWS is interested in the team behind the technology—not only in the software itself.
DuckLabs has described DuckDB, DuckLake, and Quack as building blocks for a broader generation of data services. With AWS resources and infrastructure behind the team, those components could be developed for wider use in managed services and applications, including products where users may benefit from DuckDB indirectly rather than operating it themselves.
The broader significance for cloud data
The deal highlights the growing importance of open, composable analytics components in cloud data platforms. Instead of relying only on large, standalone data warehouses, cloud providers can also build around lightweight engines that developers embed directly into applications and data workflows.
AWS is attempting to combine two assets: an open-source project with a broad developer base and a specialized team capable of database engineering at cloud scale. Keeping the projects under independent Foundation stewardship preserves the stated open-source and MIT-licensed model, while bringing DuckLabs into AWS gives Amazon a route to incorporate the team’s expertise into its analytics and lakehouse strategy.
For users, the immediate message is continuity. For AWS, the opportunity is to make its analytics portfolio easier and more efficient to use. The unresolved question is how that relationship will evolve after closing—and how the Foundation’s governance will operate as the project’s principal developers become AWS employees. AWS and DuckLabs have indicated that further plans will follow after the transaction closes.
