AgileJ
AgileJ, based in Surrey, United Kingdom, was founded in 2006 with angel investment backing. The company was created to address the problem of understanding the architectural structure of Java projects. This is true of all Java projects, but is most imperative for projects using agile methods where constant refactoring and reshaping of the structure are encouraged. Now with a mature product, AgileJ has successfully tackled the shortcomings in other UML tools, and continues to take on board ideas and suggestions from its growing community of customers.
