The AI Journal publishes a survey of the European open-source data ecosystem after a run of funding rounds, pointing to Kestra’s $25 million Series A, Polars’ EUR 18 million raise, dltHub’s $8 million, Lightdash’s $11 million, and the author’s own company Motley’s $1.5 million pre-seed, and noting that DuckDB and Polars each carry close to 40,000 GitHub stars. It argues the common thread is control over who owns data, where software runs, and how dependent customers become on a vendor, and that European institutions increasingly treat open-source data tooling as technological sovereignty rather than a procurement detail. The piece maps how the stack now spans databases, transformation engines, orchestration, BI, feature infrastructure, and semantic layers rather than a handful of standout projects.
