A European cloud for AI that cannot leave home.
Nevastack exists because the most valuable data in most companies is exactly the data that is not allowed to be uploaded to someone else's model.
How we got here
- 2023
The problem we kept hitting
Our founding team was running data pipelines for European insurers and manufacturers. Every AI project stalled at the same door: the useful data could not leave the building, and the only good models lived behind an American API.
- 2024
First private deployments
We started doing it by hand — renting GPUs, building retrieval pipelines, fine-tuning open models on-site. It worked, but every project rebuilt the same plumbing: ingestion, evaluation, an endpoint, a bill nobody could predict.
- 2025
Nevastack becomes a platform
We turned that plumbing into a product: GPU and bare-metal capacity in EU regions, a managed adaptation pipeline covering RAG, LoRA and full training, and an OpenAI-compatible endpoint at the end of it.
- 2026
Where we are now
Four European regions, one console, and a simple contract: your data stays yours, your model stays yours, and you can read the invoice without a spreadsheet.
How we operate
Your data is not our training set
Customer data is never used to train shared or public models. Isolation and deletion are contractual, not aspirational.
European by default
Compute and storage stay in the region you pick. No silent failover to another continent.
Open models first
We adapt open-weight models you can inspect, export and run elsewhere. No lock-in to a proprietary checkpoint.
Boring, legible billing
Hourly compute, a plan fee, metered inference. Every line on the invoice maps to something in the console.
