Hallo Welt!

What Hallo Welt! does

Hallo Welt! GmbH is a privately held German software company headquartered in Regensburg that develops and commercializes BlueSpice, an open-source enterprise wiki platform built on the MediaWiki foundation. Founded in 2007 with the mission of bringing Wikipedia's technology and concepts into business environments, the company began active development of BlueSpice in 2010 and has since accumulated more than 15 years of proprietary engineering work on top of MediaWiki, with a stated user base of 1M+ downloads across 160+ countries. The product is sold as either a hosted cloud subscription or a self-hosted server solution, and is complemented by a full-service offering spanning conception, installation, customization, maintenance, and support. The latest major release, BlueSpice 5.2 (2025), introduced a native AI chatbot for natural-language knowledge retrieval, improved accessibility, and chat integrations with Microsoft Teams, Slack, and Rocket.Chat.

The company serves a horizontal mix of mid-sized and enterprise customers across industries including energy and utilities (TenneT TSO, terranets bw), real estate and property management (Wiener Wohnen), construction (Max Bögl), digital marketing (Ryte GmbH), and IT hardware (Digmesa AG), with over 300 customers and a presence on three continents. Revenue mechanics combine recurring cloud subscriptions, one-time on-premise server licenses, and project-based professional services, with custom quote-based enterprise pricing that is not publicly disclosed. Hallo Welt! is founder-managed by three co-CEOs — Dr. Anja Ebersbach (Finance & Personnel), Dr. Richard Heigl (Marketing & Sales), and Dr. Markus Glaser (Software & Development) — and is bootstrapped, with no external institutional investment, parent company, or M&A activity disclosed. The company is currently scaling its sales and AI engineering functions while operating with approximately 40 specialized employees from Regensburg, with several roles open on a remote-or-Regensburg basis to support continued international expansion.

Emerging players

• Slab: Cloud-native knowledge base and internal wiki software for mid-market companies. Targets a similar enterprise knowledge management use case as BlueSpice but as a SaaS-only offering without on-premise deployment.
• Document360: Knowledge base platform focused on technical product documentation and customer-facing help centers. Adjacent competitor to BlueSpice in the structured documentation and knowledge management category.
• Guru: AI-powered enterprise wiki and knowledge management platform with browser and chat integrations. Overlaps with BlueSpice's wiki plus Teams/Slack integration positioning and recently added AI retrieval features.
• Tettra: Internal knowledge base and wiki tool focused on Slack-first teams with AI-powered Q&A. Competes with BlueSpice in the same enterprise wiki category, particularly for collaboration-tool-centric buyers.

Broad incumbents

• Microsoft SharePoint: Microsoft's enterprise content, document, and wiki management platform bundled with Microsoft 365. Directly competes with BlueSpice for enterprise knowledge management, especially in regulated and Microsoft-centric IT estates.
• Atlassian Confluence: Atlassian's flagship team wiki and knowledge management product. Competes with BlueSpice in the same enterprise wiki category but as part of a broader Agile/collaboration suite with significantly larger scale and Atlassian Rovo AI.
• Notion: All-in-one workspace combining documents, wikis, and project management with AI features. Competes with BlueSpice for horizontal knowledge management use cases, especially among digital-native and mid-market enterprises.

Others

• MediaWiki: The open-source wiki engine on which BlueSpice is built, maintained by the Wikimedia Foundation and community. Technically adjacent — Hallo Welt! is a major contributor and commercial supporter — rather than a direct competitor.

Direct peers

• XWiki SAS: Open-source enterprise wiki platform with structured data and extensibility, similar to BlueSpice in being an OSS wiki for organizations. Most direct open-source competitor targeting similar enterprise documentation and knowledge use cases.
• DokuWiki: Lightweight open-source wiki engine aimed at small teams and organizations. Competes with BlueSpice in the self-hosted enterprise wiki category, though typically at the lower end of the market.
