Greentown HQ — Boston

“Greentown Labs is, to me, the crème de la crème. It was really important for us to be in a circle of founders, leaders, thought leaders in a space where we’re trying to change the face of the industry. There’s no better place for that than being in the Greentown community. That’s the message that I have for any founders that are in this green, clean, carbontech space.”
