'''Idea Factory''' is a Japanese {{videogame}} developer and publisher, founded in October 1994 by former employees of Creator/DataEast. Its subsidiaries are Creator/CompileHeart and Design Factory.

A Western branch was opened in the United States of America in September 2013. This branch is primarily meant as a central hub for marketing and discussing its titles outside of Japan, even those that are not yet localized. However, they started localizing titles by themselves of their subsidiaries that other publishers declined to release as of May 2014. They also are beginning to dabble in PC ports via UsefulNotes/{{Steam}}, staring with the three ''[[VideoGame/{{Neptunia}} Hyperdimension Neptunia: Re;birth]]'' games and ''VideoGame/FairyFencerF''
