Although most of the Big Data players are US-based, there are a number of companies in Europe.
@LutzFinger asked me on Twitter about European players in Big Data, and I suggested a couple of European Conferences
- Big Data Europe, (with 2012 locations in Zurich, Vienna, Paris, Frankfurt, London)
- Big Data World Europe, 19 - 20 Sep, 2012, London, UK
made a list of Swedish big data companies
Mikael also commented that although most companies on his list are now based on the US, many (most?) were started in Sweden, including Recorded Future & Spotify.
@alex_mikhalev pointed to his company, Shopitize, London, UK
Atbrox is based in Norway, and they specialize in hadoop/big data and search.
I think it will be fair to add telecom giants Ericsson (based in Sweden) and Nokia (based in Finland) to European big data companies.

- DataSift, based in Reading UK, a programmable data curation platform, dealing with many millions status updates per day and many billions web pages
- new spin-off from ETH Zurich which offers big data analytics with Hadoop and Cassandra: teralytics.ch
Datameer is half German with 50%+ engineering in Germany and multiple German VPs. Does this count as european? :)
