It's not at least your support as a sponsor, that makes us one of the most important and popular events about Linux and Free Software in Germany. With a sponsorship you have the best opportunity to showcase your institution, company or anything else at the Chemnitzer Linux-Tage.

Before applying as a sponsor, please note the following information:

  • Your company, with its products, services and research areas, should fit in the free and open source software context of the event. We want to offer our visitors an invigorating blend from all areas of the open source world. Due to this approach our focus is to ensure balanced diversity of companies.

  • Sponsoring:

    Due to the change in the event concept, we are not reserving a booth quota for sponsors this year. You are welcome to apply for a stand. Also in the context of Linux-Live we offer a presentation area for companies. You can find all details about a sponsorship in the PDF document: Become a sponsor (in German).

  • Media Partners:

    We are open to media partnerships which consist of donations in the shape of book shipments, magazines or advertisements.
