Tuck Profiles: David Brewster and Tim Healy, EnerNOC

When David Brewster T'02 graduated from Tuck, green tech was not a focus for venture capitalists. “We got rejected 36 times,” Brewster says of EnerNOC, the green-energy IT company founded with classmate Tim Healy D’91, T’02 in their first year at Tuck. Times have changed. Now the company serves as a platform between businesses and some 100 utilities and is increasingly offering a suite of energy management services, helping businesses maximize energy efficiency and strategize the purchase of natural gas and electricity.
