It claims that over 600 customers, including manufacturers, ecommerce sites, media sites, and U.S. intelligence services, are using its Information Access Platform product.
It is considered a leader in the enterprise search and information access market by industry analyst firms Gartner, IDC, and Forrester Research.
The name Endeca derives from the German word entdecken, meaning "to discover."
In December 2011, Oracle Corp. completed its acquisition of Endeca.
