Hi everyone,

After the success of DF18 and DF19 editions (and the virtual DF20) we can't wait to welcome you to the stage! Please read the description below and feel free to contact us if you have any questions!

COVID Statement
DF21 is scheduled as an in-person event, speakers are expected to present on-site. The event is taking place in venue De Horst in Driebergen, The Netherlands. If local COVID rules change and hosting an in-person event is not possible we will convert to a virtual event, depending on the COVID regulations, speakers might be able to present at the venue.

What topics can be featured in DF21?

  • Business
    Your talk targets sales, marketing and project managers that might have little or no technical background. The presentation is focused on case-studies and enhancing client communication.

  • Developers
    Your talk targets .NET developers, DevOps with a strong focus on code and the technical part of working with Umbraco. The talk delves into Umbraco and will give any developer an edge in the fast-moving world of the friendly CMS.

    Your talk targets web designers and web developers. The audience can expect design-focused talks that might contain HTML, JavaScript, or CSS, but none (or very little) .NET code.

  • Something new
    We welcome new ideas that you have for a talk you believe would be a great fit for DF21 audience. There are, however, talks that we are unable to include in the program because they are too far out of the range of topics. 

How do we select the speakers?
We have a panel of reviewers with different backgrounds and perspectives. The proposals are presented to the reviewers, who then review each submission and add a comment. Once the review is finished, the next phase starts by discussing the top proposals. The decision is made based on the time slots available and the diversity of the topics.

As much as we want to accept as many proposals as possible, we are not always able to confirm a time slot for each of the proposals that received a positive review.

What format does the presentation have?
The sessions are planned to be 30 - 45 minutes long plus 10 minutes Q&A with the help of a moderator.

When can I expect to hear back from you?
01 September 2021 -- Call for Speakers open
15 October 2021 -- Call for Speakers closes
01 November 2021 -- Communication of results

Diversity pledge
We believe that a diverse environment fosters creativity, knowledge sharing, and innovation. In recent years, we have been actively seeking to increase the diversity of the DF21 attendees and speakers through the active support of a diverse speaker lineup and offering diversity and accessibility scholarships.

In this year’s event, we aim to feature speakers from different backgrounds, genders, and geographic locations in addition to a variety of organizations. We encourage people from all backgrounds, abilities, and experiences to submit their proposals.
