Non Entity Corp. is a company created in March 2005 and owned by Trent Reznor. Its purpose is not entirely clear, but it appears to have been created to handle all non-music business aspects (with the music business being handled by The Null Corporation). The company name has been spotted in conjunction with promotional photographs, websites, and merchandise.
A Non Entity Corp. II was created in 2011. Similarly to The Null Corporation II, it probably handles non-music business related to the soundtrack work.
