The Cleantech Open is a not-for-profit organization that runs the world’s largest accelerator for cleantech startups. Our mission is to find, fund and foster entrepreneurs with big ideas that address today’s most urgent energy, environmental and economic challenges.
Since our founding in 2005 by leaders in Silicon Valley and Boston, our organization has established itself as the leading force for accelerating clean technology entrepreneurs. Of the over 1,000 companies we have worked with in the United States alone, nearly half have gone on to raise external capital now totaling over ONE Billion dollars!
A network of more than 2,000 volunteers powers this process: remarkable professionals who lend their time and expertise to entrepreneurs, facilitating the growth of the cleantech industry and the positive impact that will come from such technologies.
