Nextcloud GmbH, the German company behind the open source collaboration platform of the same name, has taken on Munich-based Armira Growth as a minority shareholder. It marks Nextcloud’s first external investment in ten years: the company was founded in 2016 without outside capital and has grown organically since, according to the October 12 announcement. The founders keep the majority. Financial terms were not disclosed.

Demand is the reason given. In 2025 and 2026 Nextcloud’s lead flow more than tripled, which the company links to political and geopolitical developments, and it has doubled its workforce in response. In a Q&A published alongside the announcement, Nextcloud’s founder and CEO, Frank Karlitschek, describes the limit of self-funding: “We were profitable, but invested everything back in the company. So there are always limits.”

Key facts

  • The investor: Armira Growth, part of Armira, which manages about €5 billion, typically commits growth capital of €10 million to €100 million. The Nextcloud amount was not disclosed.
  • The control: Armira Growth holds a minority share, decision-making does not change, and the investor gets no access to user or customer data, according to Karlitschek.
  • The license: Nextcloud stays free to download under the AGPL 3.0, and self-hosting, the app store and the forums continue as before.
  • The partners: KPN, Deutsche Telekom, IONOS and Bechtle are among the major partners named in the announcement.

A €250 Million Expansion Plan Already in Place

Karlitschek founded Nextcloud in June 2016 with Niels Mache and a dozen open source entrepreneurs and engineers, after leaving ownCloud, the company he had co-founded. By the company’s figures, its growth since then has been 50 percent or more a year. Karlitschek puts the company at around 170 employees in 30 countries, as cloudmagazin reported on September 25.

The investment also feeds a plan Nextcloud had already set. In November 2025 it announced Sovereignty 2030, which earmarks more than €250 million through 2030 for research and development, products, partners, education and community projects, with a workforce set to grow sevenfold. When it announced the plan, Nextcloud aimed to achieve that growth “without venture capital or other external funding.” In Karlitschek’s account, the plan does not depend on the deal: “We’d be doing it anyway. But their money and experience lets us move faster and spend it more efficiently.” What Armira Growth brings, in his words, is “extra funding, but also experience with growing companies from 170 to 1000 people and further.”

Before the Press Release: What We See in Hosting M&A

Armira Growth’s Role as a Minority Investor

Armira Growth invests in founder-led European software and technology companies as a long-term minority shareholder and adds a network of more than 100 industry advisors. Christian Figge, a managing partner at Armira Growth, frames the fit in terms of “resilient business models with a distinct technological advantage.”

According to Karlitschek, Nextcloud is the first open source company Armira Growth has invested in, and “nothing changes in how we make decisions in Nextcloud.” The investor gets no access to user or customer data, and the AGPL license and self-hosting stay as they are.

IONOS, Telekom and KPN Among the Partners

Among the major partners Nextcloud names in the announcement are Dutch telecom provider KPN, Deutsche Telekom, IT services provider Bechtle, cloud providers Leviia and IONOS, French integrator SMILE and Destek Bilgisayar in Türkiye. Vendor figures reported by cloudmagazin put the partner network’s growth in 2025 at almost 300 percent.

IONOS shows what that channel looks like for a hosting provider. It launched Managed Nextcloud in Germany in April 2021 and brought it to the UK that July. As a Nextcloud Platinum Partner, it handles installation, system updates and maintenance in European data centers. It added Nextcloud Workspace to its platform in 2025. Both companies also back Euro-Office, an open source office suite that a coalition of more than a dozen European organizations introduced in March as a sovereign replacement for Microsoft Office.

One of the partnership’s stated aims is to “further expand the ecosystem.”
