HumHub

HumHub is a Munich-headquartered German open-source enterprise social-network and intranet platform operated by **HumHub GmbH & Co. KG** and originally spun off from the Munich web agency **zeros+ones** in early 2015 as an independent company. The codebase is built on the Yii PHP framework and licensed under **GNU Affero General Public License v3** with an optional commercial licence for buyers who need exemption from the AGPL copyleft. The product reports **4,500+ organisations** on the platform across 30+ UI languages — a customer base that spans corporations and SMEs, cities and municipalities, social and charitable institutions, foundations and clubs, political parties, and educational institutions (schools, universities). Two product editions ship: **Community Edition** is fully open-source, free to self-host on any infrastructure (Hetzner, OVHcloud, Scaleway, IONOS, STACKIT, on-bare-metal); **Professional Edition** is commercially licensed with enterprise features, formal support, and managed SaaS hosting. The **80+ optional modules** are distributed via the HumHub marketplace and cover use-cases like LDAP / SAML SSO, calendar, tasks, polls, custom pages, Mattermost-style chat, file storage, and dozens of integrations. The combination of a permissive baseline + paid-tier monetisation gives HumHub structural sustainability without requiring VC dilution — the company is HumHub GmbH & Co. KG with no PE / VC / parent on record. For procurement-grade EU buyers HumHub sits at the top of the docs / wikis / knowledge category by ownership architecture: German GmbH & Co. KG legal structure, AGPLv3 source-availability, self-host as the recommended default for sovereignty, "Open Source Software made in Germany" branded positioning, and a cross-sector public-sector + non-profit customer base that signals procurement-friendliness. Pricing for the Professional Edition is enterprise / sales-engaged; specific EUR tier figures were not captured at audit. Best fit: German and EU corporates building internal intranets and social networks, EU public-sector and educational buyers needing AGPLv3 source-availability for forking flexibility, non-profits and clubs that benefit from the free Community Edition, and any procurement-grade buyer who wants a structurally clean German open-source vendor.
