Data platforms store, combine and analyse an organisation's data: cloud data warehouses and lakehouses, data integration tools, and decision-intelligence platforms that link records from many systems for analysts and AI. Buyers in Europe choose a European vendor to keep these records, often their most sensitive, under European law and out of reach of US laws such as the CLOUD Act. The strongest European options are Exasol (Germany) for teams wanting a fast SQL warehouse under their own control, SAP Business Data Cloud (Germany) for large enterprises already running SAP and STACKIT (Germany) for large German companies needing a sovereign hyperscaler-style cloud.

Showing the 15 largest of 53. Headcount is the latest known figure.
A company counts as European if it's headquartered in Europe: the EU, the EEA, Switzerland, the UK, or elsewhere in geographic Europe, never Russia or Belarus. Headquarters means where it's run from, not a registered office. Companies founded in Europe but headquartered elsewhere today are listed separately, and a non-European owner is always named.
Each company was checked against its own legal notice, pricing page and data-processing terms, and its G2 page. The order weighs how fully each one replaces the US leaders, its track record and its ratings. No company paid to be listed or ranked.
Exasol (Germany) for teams wanting a fast SQL warehouse under their own control, SAP Business Data Cloud (Germany) for large enterprises already running SAP and STACKIT (Germany) for large German companies needing a sovereign hyperscaler-style cloud. Each is headquartered in Europe; the table compares their hosting, prices and G2 ratings.
Aiven, CrateDB, Hopsworks, Keboola and DuckDB have a free plan with no time limit.
STACKIT, Celonis, Scaleway and OVHcloud store customer data in Europe by default. Being European doesn't make a tool GDPR compliant on its own: check its data processing agreement too.
Yes: CrateDB and DuckDB, which you can also host on your own servers.
LeadWave's database lists 53 European Data Infrastructure software companies, most of them in United Kingdom (16) and Germany (7). All of them, with their CEOs' contacts, are in our list of 4,000+ European SaaS companies.
A warehouse such as Exasol stores structured data and answers SQL queries over it. A decision-intelligence platform such as Quantexa, ChapsVision's Argonos or DataWalk sits on top of many sources, works out which records describe the same person, company or asset, and gives analysts graphs, alerts and AI tools.
Yes. Exasol, CrateDB, DuckDB and Hopsworks run on your own hardware or cloud account, and Quantexa, Argonos, DataWalk and Linkurious offer on-premises installs. DataWalk and Argonos also run on air-gapped networks for defence and intelligence work.
Snowflake runs in European regions of AWS, Azure and Google Cloud, and is working on an integration with Germany's STACKIT. Palantir software can be installed in a customer's own data centre or private cloud. Both companies are American, so US law still applies to them.
