Summary

Europe is actively rebuilding its tech stack and reducing dependence on US big tech, driven by geopolitical concerns like the "digital kill switch" demonstrated by Anthropic's AI model restrictions on June 12, 2026. A Sifted Talks panel, in partnership with Proton, explored this migration, noting a Proton survey found 74% of publicly listed European companies rely on US email services. Panelists like Raphael Auphan (Proton COO) highlighted a shift from political will to risk management among CIOs, with Denmark seeing a 100% rise in Proton signups after Trump's Greenland threats. Cristina Caffarra (EuroStack) emphasized asserting European capabilities and market-led demand, while Fabrizio Pirondini (Xoople CEO) stressed the lack of European alternatives for high-scale tech and the need for significant capital investment, noting his company experienced "kill switches" on both AI and satellite imaging. Kai Zenner (European Parliament) advocated for strategic public investment in future technologies.

Key takeaway

For CTOs and CIOs managing enterprise technology stacks, the increasing geopolitical risk of "digital kill switches" necessitates a proactive shift towards European tech sovereignty. You should initiate comprehensive audits of your current dependencies on foreign providers, particularly for critical services like email, productivity suites, and AI. Develop a phased migration roadmap, prioritizing high-risk areas, to build resilience and leverage European alternatives, ensuring long-term operational continuity and data control.

Key insights

Europe is actively pursuing tech sovereignty to mitigate US dependency risks and assert its economic capabilities.

Principles

• Geopolitics drives tech sovereignty urgency.
• Market demand, not just policy, fuels tech shift.
• Strategic capital deployment is crucial for competition.

Method

Large organizations should map key IT assets, prioritize migration based on risk and difficulty, and develop multi-year roadmaps for transitioning to European alternatives.

In practice

• Assess current tech stack for foreign provider reliance.
• Prioritize migration of critical email, productivity, and AI tools.
• Explore open-source stacks for greater control and resilience.
