Houston-based advanced materials startup DexMat recently closed a Seed funding round of over $5 million.
DexMat, officially launched in early 2015, has raised approximately $10 million in funding to date, according to the latest funding data compiled by Startup Funding News. DexMat previously raised $3 million in initial Seed funding in 2023.
The 2026 Seed investment round was led by non sibi ventures, with participation from Governance Partners, Tailwind Futures, BetterWay Ventures, and Capital Factory.
DexMat plans to use the the $5 million latest funding secured in January 2026 primarily to scale up the commercial production of its flagship material, Galvorn, to meet growing customer demand.
Galvorn is a lightweight, high-conductivity carbon nanotube material used in aerospace, defense, and bioelectronics industries, as a sustainable alternative to copper, steel, and aluminum. This material is a highly conductive carbon nanotube fiber that is flexible, corrosion-resistant, and capable of replacing traditional metals in demanding, lightweight, and conductive applications.
“We’re seeing clear customer pull, particularly in wire and cable applications, as manufacturers look for conductive materials that are less dense, more durable, and resilient at scale,” said Bryan Guido Hassin, CEO of DexMat.
“This funding allows us to meet near-term demand and expand production capabilities in response to evolving supply-chain constraints,” added Bryan Guido Hassin.
