Imagine a community of bold, passionate entrepreneurs creating game-changing energy technologies that transform the way we live, work, and play.

Welcome to Greentown Labs.

Our Challenge

We face a growing global population and the resources required to meet expanding demand is today's most pressing challenge. New ways of producing and consuming energy are necessary to address this problem while minimizing further damage to our environment. We believe entrepreneurs are capable of innovating and inventing solutions to address this challenge with access to the right tools, resources, network and support. The relentless human energy of a few scientists, engineers, and business people can make a big difference. Why do we believe all of this? Because we see it every day.

Welcome to Greentown Labs

We enable entrepreneurs to solve big energy problems. Our mission is to enable a vibrant community of entrepreneurs to work on their visions and to provide access to the space, resources, and funding that allows their early-stage companies to thrive. In our new location, in Somerville, MA, just 3.5 miles from downtown Boston, we offer 33,000 sq. ft. of prototyping lab and co-located office space, a shared machine shop and electronics shop, immersion in a growing community of energy and clean technology entrepreneurs, and on-site events and programs designed to enable start-ups to rapidly grow their networks and their companies.
