FAQ: Call for Applications


Friday and September 16th and Saturday September 17th, 2022.

This year’s festival will be hosted by Engelnest co-working space in the Schöneberg area of Berlin, Germany.

This year’s festival is focused on the concept of Green Cities. With almost 60% of the world living in cities, the importance of sustainable changes cannot be underestimated. That’s why in 2022 our attention shifts to the places we call home as we invite speakers, attendees, partners, and sponsors, to come together with solutions for both the future and now!


We want to encourage innovation, ideas, exchange, and impactful connections from Berlin and around the world.

Timeline for applications

May 15th, 2022 at 23:59 (CET).

The sooner we select the sessions for the festival, the better we can plan how they all fit together into a holistic and well-rounded experience for everyone at the festival—audience and speakers. This will also allow us to share the programme well in advance of the festival, giving us ample time to promote the content and give people something to look forward to and plan for.

The Call for Applications opens on Monday April 4th, 2022 and closes on Sunday May 8th, 2022 at 23:59 (CET). Once the call is closed, we’ll take time to review all applications and plan a comprehensive and engaging programme. We’ll let you know about the success of your application latest by May 31, 2022.

No, so please make sure you get yours in before the deadline.

We’ll let all applicants know whether their submission was successful or not by May 31, 2022.


The programme is informed by the applications we receive, as well as the topics that we as a programming team have identified as particularly relevant for this year’s theme ‘Green Cities’.

What would you be excited to hear about? Begin with the audience in mind and share an idea that will help or inspire your audience. A good session is relevant, innovative, leaves the audience with something to reflect on, a learning to take with them, or implement into their work or daily life. We are looking for well-researched and in-depth content from people with expertise in that particular area.


The Call for Applications consists of three sections:

  1. Info about you as a speaker (name, pronouns, title, bio, links to your online profiles, your affiliation, and a photo)
  2. Your idea (what type of session, category, tags, title, description, etc.)
  3. Contact information and data storage and use permission.

Find the application form here.

Information relevant to the session you’re applying with will be used to promote your participation and in the festival promotional and programme materials. If your idea is accepted, your name, title, links, bio, and the title and description of your session will be made public.


Your contact details (email, phone number), as well as accessibility needs, will remain confidential.

We’re looking for thought-provoking and engaging content around inspiring ideas and impactful solutions for Green Cities. For the Call for Applications we are not accepting company pitches or promotions. If you want to showcase your business at the festival, please get in touch with us directly:
