D4V invests in Thermalytica, Developer of Next-Generation Insulation Material tiisa®
D4V has invested in Thermalytica, Inc., a deep-tech startup originating from Japan’s National Institute for Materials Science (NIMS), as the lead investor in its Series A funding round. The company is developing tiisa®, a next-generation silica aerogel-based insulation material featuring a proprietary nanostructure.
With its strong thermal insulation performance and lightweight properties, tiisa® has potential applications across a wide range of industries, including buildings and industrial facilities, liquid hydrogen infrastructure, batteries, and data centers.
As energy demand continues to grow, technologies that reduce heat-related energy loss are becoming increasingly important. We believe Thermalytica’s materials technology has the potential to contribute to greater energy efficiency and decarbonization across industries worldwide, and D4V will support the company as it brings this technology from Japan to global markets.
In addition to our investment, D4V has also supported the renewal of Thermalytica’s corporate and product brands. We will continue to work alongside the team from a design and branding perspective, helping communicate the value of its technology more clearly to customers and partners as the business scales.
