SouJava
SouJava (an acronym for "Sociedade de Usuarios Java") was founded in September 1999 by Bruno Souza (JavaMan) and Einar Saukas. It was first registered officially as a technology group in Sucesu-SP, then later publicly announced in a press conference at October 29, 1999.
Since the beginning, SouJava has always been a nonprofit organization supported by volunteer work, quite known by the enthusiasm of its members. In November 28, 2004, SouJava acquired Non-Governmental Organization status upon reaching around 35,000 members and got recognized as the world's largest Java User Group.
In 2011, SouJava became the first Java User Group nominated for the Java Community Process Executive Committee, as Java Community Process Expert Group Member. The following year, it was awarded as Java Community Process Member/Participant of the Year.
SouJava is headquartered in Sao Paulo, with branches in Campinas, Rio de Janeiro and Brasilia.
