Nebius is an AI cloud provider offering compute, AI storage, managed inference and tooling for training and deploying machine-learning models. The services are delivered as a cloud platform to businesses and developers. The operating entity named on the company's website is Nebius B.V., and the group was formerly known as Yandex N.V.
Nebius is headquartered in Amsterdam, the Netherlands, and its shares are listed on Nasdaq. The company states that it operates under the GDPR as an EU data processor and that customers can choose the geographic region where their data is stored and processed. Its newsroom describes a large data centre in Mäntsälä, Finland, inside the EU. The website does not list all hosting locations, so the chosen region and sub-processors should be confirmed in the contract. The sources reviewed name no controlling shareholder. The Dutch seat and the Finnish site give the service a clear EU footprint.
