This latest round brings the company’s total funding to $34.4 million, signaling strong market confidence in the firm’s proprietary technology designed to mitigate the impacts of extreme heat and fire on critical infrastructure.
Headquartered in Houston with a 43,000-square-foot high-volume manufacturing facility located in Katy, Texas, NanoTech is positioned at the intersection of material science and environmental sustainability. The company intends to utilize the new capital to aggressively scale its manufacturing operations, broaden its global market reach, and accelerate the research and development of its core product lines: the Cool Roof Coat, the Wildfire Shield, and the Insulative Coat: Cool Touch. These products are engineered to address the escalating costs of energy consumption and the increasing frequency of catastrophic weather events.
The Evolution of Insulative Ceramic Particle Technology
At the heart of NanoTech’s innovation is its patented Insulative Ceramic Particle (ICP)™ technology. Unlike traditional insulation materials that rely on bulk and thickness to slow heat transfer, NanoTech’s ICP technology utilizes a specialized molecular structure to repel heat at the surface level. This allows for the creation of thin-film coatings that provide thermal resistance traditionally associated with much heavier and more cumbersome materials.
The engineering behind ICP technology focuses on three primary mechanisms of heat transfer: conduction, convection, and radiation. By integrating these particles into high-performance coatings, NanoTech has developed a solution that can be applied like paint but functions as a sophisticated thermal barrier. This technology is particularly relevant for the "built environment"—a term encompassing the man-made surroundings that provide the setting for human activity, ranging in scale from buildings and parks or green space to neighborhoods and cities that can often include their supporting infrastructure, such as water supply or energy networks.
The versatility of the ICP particles allows them to be suspended in various mediums, enabling the company to serve a diverse range of sectors. From commercial real estate and industrial manufacturing to government-managed infrastructure, the applications for NanoTech’s coatings are vast, offering a proactive approach to asset protection in an era of climate volatility.

The Series A round reflects a strategic alignment between NanoTech and its investors. HPI Real Estate & Investments, a prominent player in the commercial real estate sector, views NanoTech’s solutions as a vital tool for portfolio management. Goose Capital, known for its focus on high-growth technology startups, and Milliken & Company, a global leader in diversified manufacturing and material science, provide a combination of financial backing and industry expertise.
In conjunction with the funding announcement, NanoTech has expanded its Board of Directors to include D. Kent Lance, Partner at HPI, and investor Todd Overbergen. These appointments are expected to provide the company with seasoned guidance as it transitions from a growth-stage startup to a major industrial supplier.
“Today’s built environment demands materials that don’t just meet code, but can also outperform the extreme conditions we’re now facing,” stated D. Kent Lance of HPI. “NanoTech Material’s ability to reduce operating costs by strengthening critical infrastructure is exactly the kind of performance-driven innovation this market needs.”
Halsey Cook, President and CEO at Milliken, emphasized the importance of materials science in solving real-world problems. “Innovation is a core value at Milliken, and this investment reflects our belief that materials science and advanced manufacturing can deliver real-world impact,” Cook said. “NanoTech’s differentiated technology brings new capabilities to critical infrastructure challenges where performance and resilience matter most.”
Addressing the Energy Crisis in the Built Environment
One of the most pressing challenges NanoTech aims to solve is the inefficiency of energy consumption in modern buildings. According to data from the U.S. Department of Energy, buildings account for approximately 37% of total domestic energy consumption. Within these structures, heating, ventilation, and air conditioning (HVAC) systems represent the single largest energy load.
NanoTech’s Cool Roof Coat is specifically designed to combat this issue. By significantly reducing the amount of solar heat absorbed by a building’s roof, the coating lowers the internal temperature of the structure. In various customer deployments, NanoTech has demonstrated that its coatings can reduce the cooling load by as much as 50%. This reduction does not merely represent a cost saving for property owners; it also reduces the overall strain on the electrical grid, particularly during peak summer months when heatwaves can lead to brownouts and blackouts.
The economic implications for commercial real estate owners are substantial. By lowering operational expenses (OpEx), owners can increase the Net Operating Income (NOI) of their properties, thereby enhancing the overall valuation of the asset. Furthermore, as ESG (Environmental, Social, and Governance) mandates become more stringent globally, the adoption of energy-saving technologies like NanoTech’s coatings provides a verifiable method for corporations to meet their carbon reduction targets.
Wildfire Mitigation and Infrastructure Hardening
Beyond energy efficiency, NanoTech is making significant strides in the realm of wildfire resilience. As climate patterns shift, wildfires have become a year-round threat in the Western United States and other regions globally. The economic losses associated with wildfires—including property destruction, infrastructure repair, and business disruption—are estimated to reach billions of dollars annually.
The NanoTech Wildfire Shield is an innovative protective coating engineered to withstand extreme thermal events. The product is capable of protecting wooden and structural infrastructure against temperatures as high as 3,272°F (1,800°C). Crucially, the coating is designed to be non-toxic, ensuring that it does not release harmful chemicals into the environment when exposed to intense heat—a common problem with traditional fire-retardant materials.
The company has already established a working relationship with the California Department of Transportation (Caltrans). This partnership involves developing wildfire protection standards for road infrastructure, including bridges, utility poles, and signage. Having already completed multiple projects for the agency, NanoTech is positioning itself as a key partner for government entities tasked with "hardening" public assets against the increasing threat of natural disasters.
Manufacturing and Economic Impact in Texas
The expansion of NanoTech’s operations in Katy, Texas, serves as a testament to the region’s growing status as a hub for advanced manufacturing. The 43,000-square-foot facility is equipped to handle high-volume production, ensuring that the company can meet the demands of large-scale industrial and governmental contracts.
The move to scale manufacturing is expected to create high-tech jobs in the Houston area, contributing to the local economy while providing a central logistics hub for national and international distribution. Mike Francis, CEO and co-founder of NanoTech Materials, highlighted the transformative nature of this funding round for the company’s operational capacity.
“We’re addressing one of the pressing and urgent challenges facing infrastructure owners today: controlling energy costs and extending asset life,” Francis said. “This financing marks a transformative moment for us. It allows us to rapidly scale production and bring our high-performance materials to market faster, while delivering measurable cost savings and redefining what resilience looks like in today’s built environment.”
Analysis of Market Implications
The success of NanoTech’s Series A round reflects a broader trend in the venture capital landscape: the rise of "Climate Tech" and "Hard Tech." Investors are increasingly moving away from purely software-based solutions in favor of physical technologies that address the tangible challenges of climate change and resource scarcity.
For the commercial real estate industry, the adoption of NanoTech’s products could lead to a shift in how buildings are designed and maintained. Rather than relying solely on mechanical HVAC systems to manage internal climates, architects and developers may increasingly look toward "passive" thermal management solutions integrated into the building’s skin. This shift could lead to more sustainable urban environments and reduced reliance on fossil-fuel-generated electricity.
In the utility sector, the Wildfire Shield offers a potential solution to the massive liabilities faced by power companies. In recent years, utility-sparked wildfires have led to multi-billion-dollar settlements and bankruptcies. By coating utility poles and surrounding infrastructure with fire-resistant materials, companies can reduce the risk of fire spread and protect the integrity of the grid during emergency events.
