KDE e.V. Trusted IT Consulting Firms

In KDE we take pride in being a free software community and having an open, free and fair development process.

However, we also understand that sometimes companies and institutions main priority is not learning the processes of our community and they just want issue solved or a feature implemented. For this reason, we are offering here a list of consultants that have expertise in dealing with the KDE Community and we know will help get your project landed in KDE as best as possible.

We encourage you to contact the consultants directly, but if you feel we can help you, do not hesitate to contact us at

The people currently (2024) handling mail to the consulting list are:

  • Aleix Pol Gonzalez
  • Lydia Pintscher
