Green Germany – our success story continues
Green Germany marks the next step in a journey that began over 30 years ago in Switzerland. Since then, Green has evolved from an internet pioneer into a leading provider of secure, sustainable, and connected data centers – with a strong focus on quality, sustainability, and customer proximity.
Our growth strategy follows a clear principle: to be where our customers need us – in Switzerland, in Germany, and soon at other strategic locations across Europe. We develop need-driven infrastructures that continue to set standards for the future.
As digitalization accelerates, demand for energy-efficient and future-proof data centers is growing—both nationally and internationally. Green is responding with a targeted expansion into Germany and other strategic markets, backed by the same commitment to performance that made us a trusted leader in Switzerland.
Our launch in Germany
With the founding of Green Datacenter Germany GmbH in Frankfurt am Main, we are continuing our success story by entering the German market with a clear goal: to develop modern and sustainable data centers at strategically important locations such as Frankfurt.
Our approach goes beyond simply providing infrastructure. As in Switzerland, we focus on long-term partnerships, sustainable site development, and the responsible use of resources – all with the aim of creating real value for customers, partners, and the region.
Since August 1, 2025, Heiko Siats has been serving as Managing Director of Green Germany. With his experience, he is driving key projects forward, identifying suitable locations, maintaining close ties with customers, partners, and authorities, and building strong, long-term relationships. His commitment and conviction bring Green’s values and quality standards to the German market, laying a solid foundation for our continued growth.
"For me, it’s not just about building and operating data centers – it’s about creating lasting value for our customers, our partners, and the communities we serve."
