European alternatives to Palantir

Palantir, the US data-analytics firm co-founded by Peter Thiel, has quietly become the software running behind many Western police forces, armies and health systems, stitching together vast databases to find patterns. In Europe, that has set off an argument about sovereignty: whoever runs the software that sees everything holds a lot of power, and US law (the CLOUD Act) can compel American firms to hand data to Washington.

The pushback is real and accelerating. In 2023 Germany’s Federal Constitutional Court ruled that police use of Palantir’s automated data-mining was unconstitutional, striking down Hamburg’s law and forcing Hesse to rewrite its own. In 2025 Germany excluded Palantir from a major Bundeswehr military-cloud project, and its domestic intelligence service (BfV) picked the French firm ChapsVision instead. France’s own DGSI is replacing Palantir with ChapsVision too. Swiss federal agencies have declined Palantir over CLOUD Act exposure; the Netherlands’ defence ministry says it wants off the platform within two years; and UK MPs have called Palantir the ‘most concerning’ supplier in the NHS data platform. heise

Sweden’s strongest card is Neo4j, the graph-database company founded in Malmö by Emil Eifrem. Neo4j now markets an AI layer that finds hidden connections in police investigations, and pointedly promises a self-hosted ‘Palantir replacement without a kill switch’. (Sweden’s other well-known name, the threat-intelligence firm Recorded Future, was founded in Gothenburg but bought by Mastercard in 2024, so it is no longer a sovereign option.) The European contenders are below.

Neo4j

Neo4j Sweden

Known for: the Malmö-founded graph database that put Sweden on the tech map. It now offers an AI layer that surfaces hidden links in police investigations — a Palantir replacement you self-host, with, in its founder’s words, no ‘kill switch’.

DataWalk

DataWalk Poland

Known for: a knowledge-graph platform that unifies scattered data for police, tax and intelligence agencies. Built in Europe, with full data ownership, and pitched squarely as the sovereign alternative to Palantir Gotham.

ChapsVision (ArgonOS)

ChapsVision (ArgonOS) France

Known for: its AI-driven ArgonOS platform — chosen by France’s DGSI and Germany’s domestic intelligence service (BfV) to replace Palantir.

Helsing

Helsing Germany

Known for: Munich-based defence AI, founded in 2021. Builds software that turns real-time sensor data into battlefield intelligence, and increasingly its own hardware such as strike drones and underwater surveillance systems. Backed by Spotify's Daniel Ek and valued at around €12 billion, one of Europe's most strategically important AI companies.

Quantexa

Quantexa United Kingdom

Known for: contextual data analytics for banks and governments, connecting records to expose fraud, financial crime and hidden networks.

Siren

Siren Ireland

Known for: link-analysis and investigation software for law enforcement and defence, marketed as a direct Palantir alternative.

Cognite

Cognite Norway

Known for: Oslo-based, founded 2016 by Aker Group + Bain Capital + others. Industrial data-platform (Cognite Data Fusion) + AI-driven asset-operations software for oil-and-gas, manufacturing, energy. Cognite's data-platform is one of the most-deployed European industrial-AI infrastructures.

itemis ANALYZE Germany

Known for: a sovereign investigative-analysis tool built to meet the German Constitutional Court’s privacy requirements — an explicitly European Palantir alternative.
