h

Cleantech Open is...

the oldest and largest cleantech startup accelerator program, with the mission to find, fund, and foster entrepreneurs with ideas to solve our greatest environmental and energy challenges. Through our annual business competition and accelerator program, we connect cleantech startups with the people and resources that will accelerate their success, and provide a national platform for public visibility.

Cleantech Open Northeast History

Cleantech Open Northeast was founded in 2005 as the Ignite Clean Energy program by the Energy Special Interest Group (ESIG) of the MIT Enterprise Forum. At the beginning, with less than 30 teams applying and a huge outpouring of community, business, academic, and volunteer enthusiasm, the program initially focused on student entrepreneurship at MIT and then expanded rapidly to the larger community. In 2010, Ignite expanded its reach and impact by joining forces with the national organization Cleantech Open creating the largest cleantech innovation footprint in the country. Shortly after its inception, Cleantech Open Northeast (CTONE) entered an affiliate agreement with the Northeast Clean Energy Council (NECEC). As part of this agreement, NECEC provides office space and visibility, in exchange for CTONE helping to promote NECEC’s interests and creating a pipeline for potential new members for NECEC.

Cleantech Open Northeast Covers...

Massachusetts, Vermont, Maine, Connecticut, Rhode Island, New Hampshire, New York, Pennsylvania, New Jersey, and the Eastern half of Canada. We are proud to be a central part of the highly unique and productive regional cleantech ecosystem: we work with partners all over our two regions to support the growth of innovative startups coming out of our tremendous research institutions and the business community.

Aeroshield : The 2019 Grand Prize Winner!

Startup Aeroshield from our 2019 Northeast Cohort took home the Grand Prize at this year's Cleantech Open Global Forum! A well deserved win with all their hard work and commitment during the Cleantech Open Northeast accelerator!

Aeroshield has developed a highly transparent, super-insulating silica aerogel. The nanoporous glass is composed of 95% air. By placing Aeroshield between two panes of glass, performance is now competitive with triple-pane windows at the cost and installation ease of a double-pane. This makes for a window 50% more energy efficient than 80% of windows installed in today’s homes.
