DebConf26, the 27th edition of the Debian conference is taking place at the Facultad de Ingeniería en Ciencias Hídricas of the Universidad Nacional del Litoral, in Santa Fe, Argentina. We appreciate the organizers for their hard work, and hope this event will be highly beneficial for those who attend in person as well as online.

This event would not be possible without the help from our generous sponsors. We would like to warmly welcome the sponsors of DebConf26, and introduce them to you.

We have two Platinum sponsors.

• Our first Platinum sponsor is Proxmox. Proxmox develops powerful, yet easy-to-use open-source server solutions. The comprehensive open-source ecosystem is designed to manage divers IT landscapes, from single servers to large-scale distributed data centers. Our unified platform integrates server virtualization, easy backup, and rock-solid email security ensuring seamless interoperability across the entire portfolio. With the Proxmox Datacenter Manager, the ecosystem also offers a "single pane of glass" for centralized management across different locations. Since 2005, all Proxmox solutions have been built on the rock-solid Debian platform. We are proud to return to DebConf26 as a sponsor because the Debian community provides the foundation that makes our work possible. We believe in keeping IT simple, open, and under your control.

• Infomaniak is the second Platinum sponsor. Infomaniak is an independent, employee-owned Swiss technology company that designs, develops, and operates its own cloud infrastructure and digital services entirely in Switzerland. With over 300 employees — more than 70% engineers and developers — the company reinvests all profits into R&D. Its public cloud is built on OpenStack, with managed Kubernetes, Database as a Service, object storage, and sovereign AI services accessible via OpenAI- compatible APIs, all running on its own Swiss infrastructure. Infomaniak also develops a sovereign collaborative suite — messaging, email, storage, online office tools, videoconferencing, and a built-in AI assistant — developed in- house and as a privacy-respecting solution to proprietary platforms. Open source is central to how Infomaniak operates. Its latest data center (D4) runs on 100% renewable energy and uses no traditional cooling: all the heat generated by its servers is captured and fed into Geneva's district heating network, supplying up to 6,000 homes in winter and hot water year-round. The entire project has been documented and open-sourced at d4project.org.
