Green Spaces was founded in Brooklyn in 2008 as a space for green and socially conscious entrepreneurs to launch their companies. Within a year, Brooklyn was full and achieved notable press. Beekeepers joined and kept bees on the rooftop, a urban farm was created on the roof, living walls were installed, a commercial kitchen was created in the space.

In 2009, Green Spaces moved to Manhattan and also opened in Denver, Colorado. Nearly 1000 start ups have called Green Spaces their home.

Green Space’s primary hub is in Denver, Colorado and we will also be opening in other locations around the country. If you are interested in being involved in Green Spaces and working to create a hub of socially conscious entrepreneurs, please email
