The Cleantech Open is the world’s largest cleantech accelerator, providing entrepreneurs and corporate innovators the resources they need to launch and grow successful cleantech businesses. Our one-of-a-kind innovation ecosystem built over the last 10 years of programming spans key cleantech innovation hubs in the U.S., linking labs and universities, service providers, investors, corporations, governments, and other cleantech incubators and accelerators. Through our annual accelerator, we provide between 100-150 companies in the U.S. a rich program of customer discovery, extensive mentoring, training, investor meetings, startup-corporate matching, and showcasing at both the regional and national levels. Since 2005, more than 70% of our reporting U.S. alumni companies are still operating and have collectively raised over $1.2B in external funding. Join this exciting community and be a part of our global network of innovation.
Accepted applicants to the program work with mentors, access a valuable network of professionals, and attend business clinics and webinars that provide them with the skills they need to take their business forward. In the fall, teams present their ideas for regional-level judging and are awarded prizes on the regional level. Finalist teams from regions across the county move on to be showcased in our annual Global Forum. The Global Forum showcase also features a competition among the regional winners where national prizes are awarded. If you are interested in applying to the accelerator program, please get started here.
As a non-profit organization with a small full-time staff, the Cleantech Open is run largely by volunteers. Our volunteers are united in their passion for clean technology and helping to make a difference in the world. If you are interested in volunteering or mentoring a team, please get started here.
If you are a non-US based entrepreneur, you are eligible to participate in two programs.
The Cleantech Open is looking for the best clean technology ideas from around the world. If you are a finalist from your country, your idea will be presented in a three-minute pitch in front of a crowd of 1,000 investors, entrepreneurs, sponsoring companies, corporations, members of academia, press, and others interested in hearing your ideas and getting involved.
A judging panel of cleantech experts, investors and entrepreneurs will select the winning team. You could win marketing support, legal advising, conferencing services and more to help launch your business! Get started here.
This program is focused on enhancing both emerging cleantech startups in each country and the local entrepreneurial ecosystem and policy framework. We use a competition-based approach to identify the most promising entrepreneurs across a country, while a local accelerator supports, promotes and “de-risks” the participating companies and connects them to potential investors, customers and partners.
The very best startups from each country are brought together in Silicon Valley, California, where they can both compete for the Global Prize and connect with potential partners, customers and investors from around the world. Learn more here.
