EcoWin was a provider of worldwide economic and financial market data. It was based in Gothenburg, Sweden, where it was founded in 1994. It had offices in London, Paris, New York and Gdańsk.
In November 2005 EcoWin AB was acquired by Reuters Group, later Thomson Reuters. Company's main product - time series analysis and charting toolset EcoWin Pro - has been marketed until 2013.
As of September 2015 the EcoWin Pro is being phased out. Thomson Reuters encouraged the users to migrate to the Datastream and Eikon platforms. Competing solutions include Bloomberg Terminal, Haver Analytics, Factset and Macrobond Financial.
