Based in Suwon, South Korea, and founded in 2021, Wilco Inc., a.k.a. Wilco operates as a material manufacturing company that focuses on high-heat dissipation and low-dielectric materials for the thermal management of electronic products. The company develops agglomerated boron nitride (ABN), which provides thermal conductivity and reliability than conventional boron nitride materials. In October 2025, WiLCO Inc raised KRW 5 billion in series A funding from investors COMES Investment, Albatross Investment, Company K Partners, and Mirae Asset Venture Investment. As of 2025, Park Sang-won is the CEO of the company.

The company provides agglomerated boron nitride composite (ABNC), a thermal management system that provides better thermal conductivity and reliability than conventional boron nitride for applications across thermal gap pads, thermal gap fillers, and more. Wilco offers agglomerated boron nitride in multiple series, such as the FABN series, FABN_HSA series, SABN Series, and SABN_HTD series. In addition, the firm offers RF (radio frequency) solutions laminates, an electronic solution with various properties, such as low dielectric constant, dissipation factor, high thermal conductivity, low CTE values at high frequencies for applications across antennas, satellites, power amplifiers, and more.

The company plans to utilize the October 2025 series A funding to scale up the mass production of its MARU-Series high-heat, low-k composites and expanding insulation material certifications for defense and electric vehicle electronics.
