Star Division (also written as Star-Division) was a German software company best known for developing the now discontinued StarOffice suite.

[1] After a neighbour denounced the operation of a business in a residential area to the Ordnungsamt, the company moved to Hamburg.

[1] The software had sales of over 25 million worldwide, and at its peak it had a market share among other office suites of about 25% in Germany.

[7] Star Division was acquired by the software and hardware vendor Sun Microsystems on 5 August 1999 for a higher double-digit million amount in US dollars.

[8][nb 1] Sun reintroduced the software as StarOffice 5.1a, and for the first time also free of charge for commercial use.
