WiLCO, a Korea-based advanced electronic materials company, has successfully raised KRW 5 billion in its Series A funding round. The investment was jointly led by Kommes Investment, Albatross Investment, Company K Partners, and Mirae Asset Venture Investment.

The round reflects strong confidence in WiLCO’s proprietary high-thermal-conductivity, low-dielectric Copper Clad Laminates (CCLs) and EV battery insulation materials, which are increasingly recognized as critical enablers for next-generation industries, including defense systems, automotive electronics, and AI computing hardware.

Notably, WiLCO has validated the commercial feasibility of its technology by advancing PoC (Proof-of-Concept) projects and production readiness with major global customers such as Hanwha Systems, the LG Group, and Continental AG.

The company plans to use the new capital to establish large-scale manufacturing lines for its MARU-Series high-thermal, low-K composite materials, expand certification for defense and EV powertrain insulation applications, and strengthen R&D and quality systems to support global customer engagement.

“ This investment confirms that WiLCO’s material technologies have proven, measurable competitiveness in the market,” said Sang-won Park, CEO of WiLCO. “ We are committed to becoming a global leader in advanced materials for defense, automotive electronics, and AI semiconductor systems.”

Founded in 2021, WiLCO has built its growth on proprietary technology in Low-K & High-Thermal Conductive CCLs. Its product portfolio includes the NURI, MARU, and IEUM Series, designed for antenna modules, AESA radar systems, and HPC/GPU platforms. WiLCO is actively conducting technical validation with multiple leading domestic and global companies.
