Nebius Group (Nasdaq: NBIS), formerly Yandex N.V., is an Amsterdam-headquartered AI cloud company that builds and operates GPU-dense data centers and a full-stack software platform for training, fine-tuning, and deploying AI models at scale. Its core product—Nebius AI Cloud—gives developers and enterprises access to large-scale GPU clusters, managed Kubernetes, object and file storage, and developer tooling without building their own AI infrastructure. A key product line called Token Factory provides optimized inference-as-a-service. Nebius also operates Tavily (agentic web search, now integrated post-acquisition), Avride (autonomous vehicle R&D), Toloka (AI data labeling), and Nebius Academy (developer education). The company owns and operates data centers in the US, Finland, France, UK, Israel, and is actively opening sites in APAC and the Middle East. Target buyers range from AI-native startups to large enterprises and frontier-model labs such as Meta. NVIDIA is both a major investor and deep engineering partner.
