Grant Gunnison is the founder and CEO of Zero Homes, a Denver-based firm that specializes in electrification of homes in Colorado, Minnesota, Illinois, and California. Grant gave up his post-MIT work at NASA and returned to Colorado to run his family’s construction business, shifting its focus to tackle climate change. He recognized the need to decarbonize some 60 million American homes, with 4 – 5 measures per home. What he did then was revolutionize the retrofit process, uncovering efficiencies to drive down costs and to boost the customer experience. Grant, an enthusiastic soul, has clearly been a beneficial disruptor!
