Thalassa Cloud

VERIFIED
Cloud & hosting · Netherlands
Founded 2024 · thalassa.cloud ↗

Dutch Kubernetes-native sovereign cloud (Thalassa Cloud Services B.V., Arnhem, 2024); 100% EU-owned, NL-hosted, API-first with an official Terraform provider — early-stage, no published certifications yet.

In short

Thalassa Cloud, in the Cloud & hosting category, is an EU-owned service with Netherlands as its hosting location and no identified CLOUD Act exposure.

Assessment notes

Thalassa Cloud Services B.V. (Arnhem, Netherlands; KvK 99309769, founded ~2024) is a bootstrapped, 100% EU-owned Kubernetes-native sovereign cloud — virtual machines, managed Kubernetes, managed PostgreSQL, S3-compatible object storage and VPC networking driven by an API-first control plane with an official Terraform/OpenTofu provider. Jurisdiction is clean: Dutch B.V., no US parent, no external/US VC, NL-hosted, and the vendor states no non-EU dependencies, so CLOUD Act exposure is low on its face. The score is held down by the assurance gap, not the sovereignty story: no published third-party certifications (no ISO 27001 / BSI C5 / SecNumCloud / SOC 2 — only 'via partners'), the DPA is request-only (no public URL), there is no public sub-processors list, and the platform is early-stage — a single region (Arnhem, nl-ams-1), a very small founder-led team, and several services still 'Coming Soon'. Listed for sovereignty coverage as a credible EU-owned NL option, with the early-stage and transparency caveats noted.

OVERVIEW

About Thalassa Cloud

Thalassa Cloud (operated by Thalassa Cloud Services B.V., Meander 251, Arnhem, Netherlands — KvK 99309769) is a bootstrapped, founder-led EU-sovereign public cloud built Kubernetes-native and API-first, positioned as a Dutch alternative to the hyperscalers for DevOps teams. The platform covers virtual machines, managed Kubernetes (with integrated IAM/RBAC and VPC), managed PostgreSQL, S3-compatible object storage, block and file storage, container registry, managed Prometheus and a cost explorer — all provisionable through a REST API, CLI, and official Terraform / OpenTofu / Pulumi providers. Billing is usage-based (per-minute, EUR ex-VAT): the cheapest VM is roughly €5/month, a managed Kubernetes control plane around €19.50/month, with free VPC / subnets / security-groups and free bandwidth. A "Dedicated Private Cloud" option is offered for organisations wanting isolated capacity. The sovereignty positioning is strong and clean on paper — 100% EU-owned, NL-hosted, no non-EU dependencies, GDPR-first design, NIS2 support, and Dutch Cloud Community membership — with named public-sector customers including Provincie Noord-Holland and Dienst Justitiële Inrichtingen (DJI). The caveats are maturity and assurance: founded around 2024 as a bootstrapped startup with a very small team; a single region (Arnhem, nl-ams-1) with the data-centre operator undisclosed; no published certifications (ISO 27001 / BSI C5 / SecNumCloud / SOC 2 are described as available "via partners", i.e. not currently held); a Data Processing Agreement that is referenced in the terms but available only on request; and no public sub-processors list. No GPU instances or bare-metal. Best fit: Dutch / EU teams that want a genuinely EU-owned, Kubernetes-native sovereign cloud and can accept an early-stage provider without formal certifications — not yet a fit for procurement that mandates ISO 27001 / C5 or a publicly signable DPA.
