A coalition of prominent European open-source heavyweights has joined forces to establish a new Berlin-registered entity named Open Productivity Software GmbH. The newly formed company aims to commercialize and scale openDesk, an integrated suite of office and collaboration tools built entirely from open-source applications provided by various independent vendors.
The initiative marks a significant step forward for the European open-source ecosystem, positioning openDesk as a robust, sovereign alternative to proprietary productivity giants like Microsoft 365 and Google Workspace. By offering a unified, privacy-focused workspace, the newly established firm hopes to capture the attention of critical infrastructure operators and enterprise businesses on an international scale.

Leading the newly minted company as managing directors are Dr. Gerald Pfeifer and Peter Ganten, who have been tasked with steering the enterprise through its critical growth and market expansion phases. Pfeifer brings extensive leadership experience from his previous executive roles at SUSE, while Ganten serves as the Chief Executive Officer of Univention. Together, they will oversee the commercialization strategy and manage the complex network of stakeholders required to deliver openDesk to the broader enterprise market.
The founding members driving Open Productivity Software GmbH forward are Collabora Productivity, Element, Nordeck, Open-Xchange, Univention, and XWiki. Each of these organizations contributes foundational components to the openDesk suite. Furthermore, two of the founding members, XWiki and Open-Xchange, are actively involved in the Euro-Office initiative, a document-centric project based on ONLYOFFICE that has drawn considerable attention within the European open-source community earlier this year.

What’s Inside openDesk?
The openDesk platform is not a monolithic product built by a single vendor, but rather a carefully curated suite of office and collaboration tools. Each founding member supplies a vital piece of the overall architecture, creating a modular yet cohesive environment for businesses and public administration bodies alike.
In addition to the software provided by the founding members, the suite incorporates other major open-source solutions. Nextcloud and OpenProject are integrated into openDesk to handle file management and project planning capabilities, respectively, even though they are not among the primary founders of the new company. By assembling these diverse applications into a single streamlined offering, openDesk provides users with a comprehensive digital workplace that emphasizes data sovereignty, security, and flexibility.

The project itself originated as an offering by ZenDiS, the Center for Digital Sovereignty in Germany. Until now, ZenDiS has primarily focused its deployment efforts on public administration bodies within the German public sector. However, recognizing the broader market demand for sovereign digital infrastructure, ZenDiS launched a private-sector partner program for the openDesk suite just last month, laying the groundwork for this latest commercial push.
How the Partner Model Works
To successfully navigate the enterprise market, Open Productivity Software GmbH is adopting a structured partner-led delivery model. Customers purchasing or migrating to openDesk are intended to deal with a single, designated contact per project. This primary point of contact will oversee the entire lifecycle of the deployment, ranging from initial consulting and legacy system migration to day-to-day operations and ongoing support.

While the software itself can be hosted flexibly, details regarding whether the hosting will take place strictly on a customer’s own local infrastructure or within specialized cloud environments are still actively being refined by the company and its partners.
To ensure a strong launch, three prominent launch partners are backing the newly formed company from day one. Adfinis, a Swiss-headquartered open-source enterprise, brings deep technical implementation experience; the msg group contributes extensive expertise in serving critical infrastructure operators; and French firm Smile adds specialized systems integration capabilities to the roster. At this stage, Open Productivity Software GmbH has not yet disclosed whether additional integration partners will be onboarded following the initial market launch.

The strategic alignment between public sector initiatives and private enterprise was underscored during the launch by Pamela Krosta-Hartl, the Managing Director of ZenDiS. Expressing strong support for the new venture, Krosta-Hartl noted that the initiative by several openDesk vendors to establish Open Productivity Software GmbH paves a clear path for the suite’s entry into the broader enterprise market. She added that the new company effectively empowers the distributors and systems integrators that ZenDiS is actively addressing through its newly established partner program.
