Day Software AG was a Swiss company that created the underlying technology of Adobe Experience Manager.[1]


The predecessor to the company was founded in 1993 as Bidule AG in Basel, Switzerland.[2][3] On August 13, 1999, Bidule merged with Day Interactive Switzerland AG to form the Day Group.[4] Day's primary product, Communiqué ("CQ") was based on its ContentBus architecture and was launched in early 2000 as a set of CGI scripts for Netscape Enterprise Server.[1]
