A Houston startup that has developed an innovative coating material that can reduce energy consumption has raised fresh funding for its cross-country expansion.

NanoTech Inc. announced its latest funding news — an oversubscribed funding round that brings onboard a handful of new investors. The details of the round were not disclosed, but NanoTech did release that the round included participation from three institutional investors, two corporate-strategic investors, and seven family offices. These entities join initial investor, Austin-based Ecliptic Capital.

NanoTech's flagship product is a waterproof thermal coating, called the Nano Shield Cool Roof Coat, which began rolling out across the country this year. Not only does the product reduce energy costs for the building owner, but it reduces emissions as well.

"It's crucial to recalibrate the sustainability narrative – environmental responsibility and financial return can go hand in hand," says Mike Francis, CEO and co-founder of NanoTech, in a news release. “We’ve transformed the roof from a cost center to a savings source by reducing energy expenditures while also significantly shrinking the building's carbon footprint.”

"The substantial decline in CO2 emissions and energy costs resulting from reduced reliance on HVAC systems is far more than a fringe benefit — it forms the cornerstone of our long-term strategy to lead the climate-resilient materials market. Beyond corporate objectives, it's a personal source of immense pride to foster a healthier planet for generations to come," Francis continues.

As the first selected company in Houston-based Halliburton Labs, NanoTech continues to benefit from the incubator's industrial scaling resources. Francis and Chief Commercial Officer Carrie Horazeck recently joined the Houston Innovators Podcast to discuss the impact their product is making as they roll out nationwide.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues.
