Green River

At Green River, our mission is to leverage technology to create a better world. We are dedicated to using our powers for social good, and we're proud to have spent the past two decades building a business around impact. To do our part, we build sustainability analytics software to manage critical business and social processes in the pursuit of transparency, accountability, and continuous performance improvement. At a time when polished platforms offer ready-made tools for the classroom to the board room, Green River's dynamic custom developments let us combine creativity and artisanal values with the best technology the web has to offer. Green River's team of 20 designers and engineers collaborates with clients including Starbucks, US Green Building Council, NBCUniversal, B Lab, City of Boston, Commonwealth of Massachusetts, World Resource Institute, and many others. We are based in scenic southern Vermont, and we have staff who are distributed throughout the United States.
