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.
