Goldstar Incorporated was first created by Booster Gold with the help of Dirk Davis and Trixie Collins.  The name was going to be Booster's superhero name but when Booster met President Ronald Reagan he panicked and said his name was Booster er Gold... and that is where he got his name.  Shortly after that he decided to name his company Goldstar Incorporated.  
 
Booster used Goldstar Inc. to make money as a superhero.  It was located in  Reilleau Towers After the company and building were destroyed he reformed it as Booster Gold International and moved into a mansion.
