​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!

Zero Homes is unique in many ways: Its primary focus is on electrifying homes... their space and water heating, cooking, etc, to help solve the climate crisis. He works to upgrade electrical panels to make homes ready for heat pumps, EVs, and solar systems. Of note, Zero Homes has reformed the front end of all construction processes... the process of bidding on construction jobs. Zero Homes provides interested parties with an online tool. It gives homeowners some homework... wiping out the inefficiency of multiple firms coming to the property to analyze and compete for opportunities for jobs and savings.

Grant came up with the business model after working on his family's construction business. Free quotes cost all contractors and their customers time and money. By using Zero Homes' online tool, homeowners take photos and videos of their home and provide other pertinent data Then Zero Homes builds a 3D model of the home and identifies and prices measures for decarbonization. Zero Homes collapses the sales cycle; it also provides the design and quality assurance services. As a licensed general contractor, Zero Homes maintains a roster of vetted subs who complete the installations. Zero's process is faster and more efficient, and the result is projects that cost ~10% less while improving both the contractor and customer experience.
