NdotLight lands 15B KRW Series B for physical AI training data
What's the deal? South Korean physical AI data company NdotLightDealroom has a profile for this one. Try Dealroom → has raised 15 billion KRW (roughly $10.6 million) in a Series B round, it announced in August 2026. Korea Development BankDealroom has a profile for this one. Try Dealroom → led the round.
Who's in? Existing backers Naver D2 Startup FactoryDealroom has a profile for this one. Try Dealroom →, IMM InvestmentDealroom has a profile for this one. Try Dealroom →, and Capstone PartnersDealroom has a profile for this one. Try Dealroom → joined the follow-on, while NH Venture InvestmentDealroom has a profile for this one. Try Dealroom →, OurCrowd, and StonebridgeDealroom has a profile for this one. Try Dealroom → came in as new investors. For Naver D2 Startup Factory, it is the third investment in NdotLight after its pre-Series A in 2021 and Series A in 2022.
What does it do? NdotLight builds Trinix, a solution that generates "sim-ready" 3D assets for use in simulation and digital twin environments. Its data automates 3D generation that reflects physical properties such as mass, friction, joint structure, and collision range, addressing a bottleneck in physical AI and robot learning: securing large-scale, high-quality training data.
Why it matters: Traditional data collection based on teleoperation or motion capture has been dogged by quality variance, high cost, and slow speed. NdotLight's system connects to NVIDIA's Omniverse simulation platform to generate high-quality 3D data at scale, from creation through evaluation.
Who's using it? The company supplies data for physical AI projects at large firms including Hyundai MotorDealroom has a profile for this one. Try Dealroom → and LG ElectronicsDealroom has a profile for this one. Try Dealroom →, and provides AI training data to humanoid robot and robot foundation model companies such as Holiday Robotics, AerobotDealroom has a profile for this one. Try Dealroom →, and RealworldDealroom has a profile for this one. Try Dealroom →. In May 2026, it was listed as a physical AI ecosystem partner during NVIDIA chief executive officer Jensen Huang's keynote at GTC in Taiwan.
What's the endgame? NdotLight will use the funds to advance its generative CAD engine and materials database, and to expand Isaac Sim and Omniverse workflow integration. It also plans to hire for global expansion and technical development.
What they said: "The core of the physical AI era depends on how efficiently you can secure high-quality data that is immediately trainable in simulation environments," said chief executive officer Park Jin-young, who co-founded the company with chief technology officer Kim Sun-tae.
The signal: The round ranks in roughly the top 42% by size, a solid but not outsized raise reflecting steady investor appetite for the data infrastructure underpinning physical AI and robotics — the layer companies must build before humanoids can learn at scale.
