Office.eu: A European Alternative to US-Owned Cloud Platforms

On March 4, Office.eu launched in The Hague as a European-owned sovereign alternative to Microsoft 365 and Google Workspace. All data is stored exclusively in European data centers, ensuring it remains beyond the reach of US law. The platform is built on Nextcloud and is fully European-owned.

Rising Demand for European Sovereignty in Cloud Solutions

European institutions are increasingly seeking alternatives to US-owned cloud platforms. In November 2025, the International Criminal Court transitioned from Microsoft 365 to a European open-source office suite. Microsoft has openly acknowledged that it cannot guarantee EU cloud data remains outside the reach of US government requests.

Office.eu is entering a market fueled by institutional shifts and well-documented concerns over the sovereignty guarantees provided by US-based providers.

Comprehensive Functionality and Regulatory Compliance

Office.eu offers a complete office suite that includes email, document editing, file storage, and collaboration tools. The company emphasizes that all data remains under European legal jurisdiction, fully compliant with EU data protection regulations, and not subject to US law or government data requests.

Founded in 2024 and headquartered in The Hague, Office.eu is currently rolling out by invitation to selected clients. A broader, phased European launch is scheduled for Q2 2026. Pricing will be comparable to Microsoft 365 and Google Workspace, and migration tools are available for customers switching from these platforms.

Target Market and Growth Potential

Early adoption has been seen across Europe, with growth expected particularly among individuals and SMEs. European governments and public institutions are also key potential customers, driven by mounting regulatory pressure to keep sensitive data on European-owned infrastructure.

Geopolitical Context: The Push for Digital Sovereignty

Regulatory pressure reflects a broader geopolitical shift. European policymakers are increasingly prioritizing digital sovereignty. Belgium’s cybersecurity chief recently described reliance on US-origin technology as a significant security concern. European tech leaders have urged the European Commission to foster homegrown alternatives, reinforcing the strategic importance of sovereignty in the digital domain.

CEO Maarten Roelfs positioned Office.eu as a direct response to this dependency on US-owned platforms. While US providers like AWS and Microsoft have introduced "sovereignty-branded" products, these offerings remain subject to US jurisdiction, making European-owned platforms like Office.eu a distinct option for organisations prioritizing full independence.

Challenges and Criticisms

Despite its sovereignty-focused appeal, Office.eu faces several practical challenges:

• Higher Costs: Sovereignty initiatives often result in increased expenses and diverted investments.
• Market Fragmentation: Fragmented digital markets across Europe pose challenges to scaling a continental platform.
• Lack of Open Standards: Critics have noted the absence of open standards and formats, raising concerns about potential vendor lock-in.

Policy analysts also highlight broader trade-offs in Europe’s sovereignty agenda. Efforts such as EuroStack, domestic procurement mandates, and data localization may support sovereignty but risk undermining the integrated digital economy that drives innovation and scale.

The Strategic Importance of Sovereignty

For European organisations handling sensitive data under GDPR, the choice between a US-owned sovereign cloud — even one with a completed EU Data Boundary — and a fully European-owned platform has significant regulatory implications. Office.eu’s phased rollout in Q2 2026 will be a critical test of whether sovereignty concerns translate into sustained customer adoption at scale.
