Cleantech Open is the world’s oldest and largest cleantech accelerator and business plan competition. Our mission is to find, fund and foster entrepreneurs with big ideas that address today’s most urgent energy, environmental, and economic challenges. A 501(c)(3) not-for-profit organization, Cleantech Open provides the infrastructure, expertise, and strategic relationships that turn clever ideas into successful global cleantech companies. Over the past eight years, Cleantech Open has awarded over $5 million in cash and services. During that time, our 1,600 alumni companies have raised more than $1.2 billion in external funding. Fueled by a network of more than 2,000 volunteers, Cleantech Open unites the public and private sectors in a shared vision for making America’s cleantech sector a thriving economic engine.  

NECEC is the Northeast regional affiliate for Cleantech Open, executing the Northeast accelerator and business plan competition and building the region’s innovation network with NECEC’s successor program for cleantech entrepreneurs, Navigate.
