Data Residency

Where is your data stored and processed?

Poolside: On-premise and VPC deployment with zero data egress. Customer code never leaves the customer's environment. EU organisations can deploy on their own EU infrastructure. Maximum data sovereignty.

Nebius AI: Data centres located in Finland and the Netherlands—both EU member states. Inference and compute workloads remain within EU borders. Strong data residency story for European AI builders.

Legal Jurisdiction

Which laws govern the company and your data?

Poolside: Delaware incorporation (US). French SAS entity exists but parent is US. CLOUD Act applies to the corporate entity, though on-premise deployment means code never reaches Poolside's infrastructure.

Nebius AI: Incorporated as Nebius Group N.V. under Dutch law. EU legal jurisdiction applies, with no CLOUD Act exposure. Corporate history as Yandex spin-off warrants due diligence on ownership structure, but current governance is EU-based.

Poolside: On-premise/VPC mode: customer has full control, no data leaves their environment. Training uses synthetic data (RLCEF), not customer-contributed code. Structural separation.

Nebius AI: Customer inference requests and training data are not used to train shared models. Tenant isolation architecture. GDPR-compliant data processing posture with configurable retention for enterprise customers.
