ColSpace was founded in 2000 by Matthew Greenhouse. ColSpace grew out of the concept that companies should be able to easily acquire standardized, "out of the box" collaboration solutions that can be customized and augmented for individual businesses' needs. ColSpace's collaboration solutions are now used by a distinguished list of companies including Omnicom, OMD, DDB, Clorox, Bechtel, and T-Mobile.

As CEO, Matthew has drawn upon his experience in designing and implementing software applications for the leading global corporations. In addition to his e-commerce and software engineering experience, Matthew has an extensive background in developing collaboration solutions for the advertising, engineering, and media industries. Some of the platforms he created are now considered the standard in these corporate sectors.
