Wikis for agile companies
Hallo Welt! GmbH is one of the leading specialists for the Wikipedia software MediaWiki.
We are the company behind BlueSpice, the open-source enterprise wiki software, which is distributed in more than 160 countries with over 1,000,000 downloads.
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.
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.
