N.Light, a South Korean physical AI data company, has secured KRW 15 billion in new funding.
The round was led by the Korea Development Bank (KDB). Existing investors Naver D2SF, IMM Investment, and Capstone Partners returned with follow-on investments, while NH Venture Investment, OurCrowd, and StoneBridge Ventures joined as new backers. Naver D2SF’s participation marks its third investment in N.Light, following a Pre-Series A round in 2021 and a Series A round in 2022 — a long-term partnership that has included N.Light’s residency at Naver’s 1784 headquarters and joint development of 3D content production environments.
Founded in South Korea in January 2020 by CEO Park Jin-young, who previously led 3D launcher development at Samsung Electronics, and CTO Kim Sun-tae, who led AI and 3D engine development at Naver and Samsung Electronics, N.Light is a Korean company that develops TRINIX, a “sim-ready” 3D asset generation solution built to solve one of physical AI’s biggest bottlenecks: the shortage of high-quality, simulation-ready training data. Traditional approaches to collecting robot training data — such as teleoperation and motion capture of real-world movement — have long struggled with inconsistent data quality, high cost, and slow collection speed.
N.Light’s pipeline automates the generation of 3D data that incorporates physical properties such as mass and friction, along with joint structure and collision-boundary information, integrating with Nvidia’s Omniverse simulation platform to produce large volumes of high-precision 3D simulation data for use in simulation and digital-twin environments. The company already supplies training data to major Korean conglomerates’ physical AI projects, including Hyundai Motor and LG Electronics, and to humanoid robot and robot foundation-model developers such as Holiday Robotics, A-Robot, and Realworld. N.Light was named among the “physical AI ecosystem partners” featured in Nvidia CEO Jensen Huang’s keynote at GTC Taiwan in May, and has been recognized by global venture research firm CB Insights as a notable 3D engine company.
N.Light said it will use the new capital to advance its generative CAD engine and physical-properties database, and expand integration with Nvidia’s Isaac Sim and Omniverse workflows. The company also plans to hire talent across all functions to support global market expansion and further technology development.
