Zero Homes Secures $16.8M in Series A Funding Led by Prelude Ventures

Zero Homes just pulled $16.8M out of the atmosphere and turned it into oxygen for the electrification economy. Series A. Real capital. Real conviction. Prelude Ventures leading the charge, with SJF Ventures, Watsco Ventures, and returning hitters VoLo Earth Ventures, Overture VC, and FJ Labs doubling down. Money talks. This round is speaking in full sentences.

Congratulations to Grant Gunnison, Founder and CEO, who went from swinging hammers in a family contracting business to engineering systems at MIT and then deciding the home upgrade process deserved less clipboard and more code. That arc is not theory. That is field grit meeting first-principles thinking. And it shows in the product.

Zero Homes is not selling heat pumps. Zero Homes is selling certainty. A digital-first home upgrade platform that builds a high-fidelity model of your house from a smartphone walkthrough. No parade of truck rolls. No guesswork dressed up as experience. ACCA-standard Manual J calculations. Remote design. Department of Energy validation on sizing quality. The kind of precision that makes contractors faster and homeowners calmer.

Justin Holmes, Head of Engineering and Product, and Wayne Mock, Head of Engineering, are wiring the backbone. Rolly Sarmiento and Charlie Hamilton bring principal-level firepower to the code. Sean Chapel keeps the software sharp. Dean Howard anchors Design and Quality so the installs match the math. Matt Woodward and Walter Funke shape the product experience so it feels simple, even when the physics is not. Emily Johnson runs Project Operations where timelines live or die. John Young leads Field Operations so local installers execute like pros. Christian Kennedy guards Finance and BizOps so growth does not outrun discipline. Lizzy McNevin drives Marketing with clarity. Eric Stonebraker advises on electrification. John Meissner operates as CXO and Advisor, Interim Head of Growth, because scaling this category takes more than ads and ambition.

Headquartered in Denver, Zero Homes is already installing across Colorado, Massachusetts, Minnesota, Illinois, and California. The plan is expansion in 2026, broader product offerings, and a deeper contractor network. Translation: more homes modeled, more systems electrified, more friction removed from a market that has been begging for coordination.

Home electrification has been a maze of rebates, load calculations, and crossed fingers. Zero Homes makes it a map. Investors see the wedge. Contractors see efficiency. Homeowners see a path that feels engineered, not improvised.

$16.8M says the market is ready for upgrades that start with software and end with comfort. The only real question is how many roofs will be scanned before the rest of the industry admits the future is already inside the house, waiting to be modeled.
