History
Aceize is an abbreviation of the words spACE colonIZE. The concept behind Aceize was originally formulated in the summer of 2006 in Richmond, VA by Greg Kontos, Shawn Nash and Jimmy Gilmer, and a shadowy 4th conspirator. This dubious trio set in motion a company that has a 150 year business plan to put a human colony on a planet suitable for human habitat without the need for life support systems.

At the close of the first six months of business Aceize has received $0.25 of private investment capital. All of the original principles of the company have abandoned the project with the exception of Greg Kontos.
