Knowledge is our mission

Wikis for agile companies

Hallo Welt! GmbH is the company behind BlueSpice, the open source enterprise wiki software used in more than 160 countries with over 1,000,000 downloads. We are committed to open source software and are one of the world’s leading supporters of MediaWiki.

We are the Hallo Welt! GmbH

We founded the company in 2007 to make the technologies and concepts of Wikipedia usable in the business environment. Since 2010, we have been developing our core product BlueSpice for operating professional wikis in companies and organizations. BlueSpice is the result of ten years of development work, a strong understanding of the MediaWiki foundation, and knowledge of corporate requirements.

Wikis – our passion

We believe that wikis are the best tools to quickly find or share knowledge. We are fascinated by the task of building easy-to-use, standardized enterprise software.

A strong team

Our specialized team of more than 30 employees ensures that the wikis of more than 300 customers from all industries and in three continents are optimally planned, implemented and supported.

Technology & innovations

Our software integrates state-of-the-art frameworks, new technologies, and standards. We optimize, automate, test, and publish it in our cloud services or as a server solution.

Service & support

We deliver the whole program: from design, installation and development to maintenance and support.

Our vision

We see our work as a contribution to a future in which people can openly share experiences, expand their knowledge and collaboratively shape the future. For us, open-source software and free knowledge are conditions for the development of new ideas and standards. That is why we are developing BlueSpice, an open-source standard wiki, in close cooperation with the various MediaWiki communities.

Our team

Our employees are important to us and we are proud of what they accomplish every day! In our team, a wide variety of experts come together to further develop our software and optimize our services. In this way, Hallo Welt! is ideally positioned to continue to grow and to take on new challenges all the time.
