The COVID-19 pandemic has hit the events industry hard and prices for nearly everything have gone up drastically. The Russian war of aggression against Ukraine further exacerbates this price hike. Most costs for event related services have risen even more than the general inflation numbers suggest and in order to make FOSS Backstage happen, we too have to increase ticket prices. We still tried to keep the increase reasonable and have Reduced Tickets available for people facing socio-economic hardships. Also keep in mind that we have gone from an event with one day online and one day onsite, to a two day onsite event.

In order to promote this diversity and inclusivity at FOSS Backstage, we have initiated a diversity tickets program. Diversity Tickets are fully sponsored (i.e. free) tickets that are available to people from underrepresented groups within the FOSS Backstage community. This includes, but is not limited to: women, people of colour, LGBTQIA people, disabled people, and people facing economic or social hardships.

The proceeds of Diversity Fund Contributions are put in a pool to pay for Diversity Tickets. Diversity Fund Contributions enable us to use your resources to support someone who might otherwise be unable to attend.

Please note that Diversity Fund Contributions are not tickets for FOSS Backstage (even though they are sold through our ticket shop) and therefore don’t grant access to our venue in Berlin nor to our online event platform.

In your order confirmation and your payment confirmation emails you can find a link to your order details page. Use the change details button in the “Ordered Items” box to change the attendee name.  A ticket is only valid for one person and cannot be shared.

Yes, all of our Standard Tickets also include access to our Online Event Platform, where you can watch livestreams and interact with other online participants.
