DuckLabs is the company that does consulting and DuckDB development, the DuckDB foundation actually owns DuckDB the project.
The DuckDB foundation owns some equity in MotherDuck, which is a data lakehouse platform based on DuckDB, and all three have been moving closely together in making DuckDB better locally as well as in the role of a query engine that really threatens a lot of amazon's role in data lakehouses. DuckDB in the hands of a good team means that you can use AWS almost only for storage, instead of using any of the managed services.
