- Liner
Participated · Series C · Aug 2026
Liner operates AI-powered search and agent services and has expanded from consumer-facing offerings into B2B enterprise solutions using accumulated global traffic data and academic records. The company reports roughly 14 million users across about 220 countries and has compiled approximately 500 million academic data records to inform its models. As of late July 2026, Liner ranked 30th in SimilarWeb’s global AI service traffic rankings. Liner plans to continue investing in core technology and infrastructure to widen its competitive gap and to secure global talent while growing marketing and business operations. The company aims to diversify its B2C business model and adapt agent technology proven in overseas markets for broader adoption in South Korea. The recent Series C funding is intended to underpin those R&D and expansion efforts.
- BEI
Participated · Series B · Aug 2026
BEI develops and manufactures anode-free lithium metal batteries designed for high energy density and power; its current-generation cells exceed 500 Wh/kg according to the company. Independent testing by About:Energy confirmed leading energy density and power characteristics, and a BEI-powered drone demonstrated over 30 minutes of flight at −26°C during a field demo in Finland. BEI reports more than 30 global UAV customers are evaluating or deploying its cells, which are already integrated into operational small unmanned systems. The company is commercially shipping its AFLMB cells today while advancing a roadmap targeting future cell generations with energy densities above 600 Wh/kg. With the Series B proceeds, BEI plans to scale manufacturing, run customer qualification programs, and expand commercially across Korea, the U.S., and Europe. Strategic partnerships and investor relationships aim to strengthen supply-chain resilience and support adoption in defense, robotics, and electric mobility markets.
- NdotLight
Led · Equity · Aug 2026
NdotLight develops TRINIX, an automated pipeline that generates simulation-ready 3D data with physical properties (mass, friction), joint structures, and collision boundary information for use in physical AI training simulations. TRINIX integrates with NVIDIA Omniverse to supply large-scale, high-quality 3D simulation datasets. NdotLight currently provides AI training data to humanoid robotics and robotics foundation model companies including Holiday Robotics, AeiRobot, ROBROS, and RLWRLD, and participates as a data supplier in projects led by Hyundai Motor Company and LG Electronics. The leadership team includes CEO Jinyoung Park (previously on 3D launcher development at Samsung Electronics) and CTO Suntae Kim (who led AI and 3D engine development at NAVER and Samsung Electronics). The company has been named by CB Insights as one of the world's notable 3D engine companies and is actively hiring to support growth.
- Ready Robust Machine
Participated · Series B · Aug 2026
Ready Robust Machine develops hardware and software energy-recovery solutions for hydraulic heavy equipment, centered on its READi X system and an agricultural variant READi T. The company has validated fuel-efficiency improvements in industrial deployments, reporting up to 36% improvement on 30-ton Hyundai excavators, up to 19.4% on 50-ton Hyundai excavators (a claimed world-first for 50-ton class), and average gains above 16% in Japanese tests on Shin-Ei and Sumitomo machines. Its business has shown growth: first-half sales exceeded the prior year’s annual sales and the company reported an order backlog over 2 billion won. Ready Robust Machine plans to scale manufacturing, expand a nationwide installation and maintenance network, and commercialize data services such as Zero Downtime to extend applications to tractors, cranes and other hydraulic equipment. The company is also pursuing global expansion through its Japan subsidiary and aims to launch a plug-in hybrid large excavator capable of more than 10 hours of operation on a single charge within the year.
- MID
Participated · Series A · Jul 2026
MID develops and manufactures space-grade electronic components and operates a consulting business for space product assurance, leveraging its Component Procurement & Provision Activity (CPPA) platform. The company localized a hermetically sealed ceramic-package 16Mbit SRAM designated as a ‘Space New Technology’ and installed on a technology validation satellite launched on the Nuri rocket. It is developing a non-hermetic epoxy-molding high-capacity NAND flash (128Gbit or more) intended for the ultra-small satellite DaejeonSat to be launched on the fifth Nuri mission. MID plans to build a 6,600-square-meter advanced packaging line in Daejeon and to scale mass-production processes for HTCC ceramic packages. The company reported revenue rising from about KRW 1.9 billion in 2021 to roughly KRW 12.4 billion last year and aims to expand into commercial and defense markets while establishing production for ceramic components used in semiconductor test equipment by 2029.
