Let’s reinvent buildings, old and new.
The buildings sector contributes seven percent of global greenhouse gas emissions; to change this, we need innovations that revolutionize how buildings are planned, built, retrofitted, and managed.
Greentown Go Build brings together startups and corporates to accelerate the commercialization of technologies from building materials to building management systems, and more. How can you help build a decarbonized future?
Let’s Go.

“There’s no better way to accelerate the growth of a company. There are a lot of things about building a company that aren’t straightforward, and to have Greentown understand and have mentors who have been through fundraising and know how to think about your product—it’s beyond measure, the value that provides.”
