What Nebula Link does

Nebula Link (星云互联) is a Chinese C-V2X (Cellular Vehicle-to-Everything) technology company founded in 2015 by a Tsinghua University research team led by Professor Yao Danya, originator of the 'vehicle-road collaboration' concept in China. The company develops a full-stack vehicle-road-cloud integrated intelligent transportation platform built on four proprietary technology pillars: a self-developed V2X trusted interaction kernel supporting hundreds of vehicles per kilometer with millisecond latency, a layered-decoupled V-KEY V2X protocol stack, a full-scenario algorithm library with multi-source data fusion, and the V-Lab hardware-in-the-loop test toolchain covering L0-L4 mass-production R&D. All core technology is 100% self-developed with proprietary IP.

The product portfolio spans three domains: Smart Vehicles (V-Box/VT-Box onboard terminals, CDAS cooperative driving assistance system, V-KEY V2X protocol stack, V-Lab simulation testing toolchain), Intelligent Roads (T-Station intelligent roadside terminals, roadside perception systems with multi-sensor fusion, Guanxing V2X message analyzer), and the Collaborative Cloud (X-Cloud control foundation platform integrated with DeepSeek AI, plus an application platform with six modules). Nebula Link has commercialized 5M+ V2X protocol stack authorizations across 30+ automakers including BMW, NIO, Great Wall Motors, Volkswagen, Hyundai Mobis, and Junshan, with deployments in 50+ cities and 3,000+ intersections covering 70% of China's dual-intelligence pilot cities.

The company generates revenue through four streams: hardware sales (V-Box/VT-Box onboard units and T-Station roadside units), V-KEY protocol stack licensing and royalties to automotive OEMs and Tier 1 suppliers, project-based smart transportation infrastructure contracts with municipal governments (Liuzhou, Shenyang, Cangzhou, Hefei, Beijing-Xiongan Expressway), and cloud platform services including the X-Cloud subscription offering. Nebula Link is the primary drafting unit for China's C-V2X application layer standards (Phase I and Phase II) and a contributor to 40+ national and industry standards, providing a regulatory moat that anchors its market position. As the originator and recognized 'first stock' candidate in China's vehicle-road collaboration sector, the company has raised approximately RMB 300M in Series B and B+ rounds during 2022 and signed an IPO counseling agreement with Guoyuan Securities in 2021.
