Climate Tech Start-Up NxLite Closes US$4 Million Series Seed Funding Round, Secures C$5M in Funding from Sustainable Development Technology Canada

NxLite (formerly 3E Nano Inc.), a climate technology start-up poised to disrupt the window market, today announced it has secured a US$4 million Series Seed funding round. The syndicated raise was led by Energy Foundry and includes major investors MUUS Climate Partners, ACT Venture Partners, Creative Ventures, and New Climate Ventures, with additional climate impact investors including Vectors Capital and VertueLab.

Government Backing

Additionally, the company has received CAD$5 million in follow-on funding from Sustainable Development Technology Canada (SDTC)—a Canadian Government program focused on finding, funding, and fostering Canadian companies that develop and commercialize technologies that positively impact Canada’s environmental and economic prosperity.

The Technology

NxLite’s patented thermal energy control nano-coating is a transparent, flexible, and low-cost solution that will transform the window market, quadrupling a window’s R-value, or insulating effectiveness. With commercialization funding now secured, the company will finalize product development and commercialize the technology over the next three years.

The Market Opportunity

The global window market is valued at over $150 billion, and energy-efficient glazing is one of its fastest-growing segments. NxLite’s technology addresses a critical gap by enabling high-performance coatings on materials beyond traditional glass, including polycarbonate and acrylic.
