General information

A sprint-like event where participants team up and create solutions to real-life challenges in an intense period of time. Using creativity, technology and mentoring, the week results in prototypes, fresh new concepts and innovation.

The event is organized in Budapest, however there is a possibility to join online. We will use an open Slack workspace as the main platform for communication, Junction App for the hackathon submissions and social media for the opening, closing ceremonies and additional programs of the event.

  1. Find your teammates. Or apply solo, and ask to be added to a brand new team if you want. Lone wolves are also welcome. 
  2. Register and mark whether you would attend offline or online on the event!
  3. Join us on the 24th of November and start brainstorming.
  4. Work on your solution with your team.
  5. Feel free to request mentoring on your project from experts.
  6. Submit your project video by 10:00 on Sunday.
  7. Take home your prize!

Of course. Hackathons require not only programming and designing, but also various roles including service planning and project managers. Don’t worry and apply!

The event’s language is English from start to finish, including the mentorings and the pitch sessions.

Yes, you can enter the hackathon for free.

You can find information about this at the Evaluation process part.

JunctionApp uses an algorithm named Gavel to judge projects. In this pairwise-comparison-based algorithm participants review each other’s projects. The system incorporates a lot of research on mathematical psychology along with fancy math, resulting in a fair and scalable reviewing system. The user is always given two projects to compare, asked to vote for the better one and compare the newer project to the next one (and so forth). This way, one doesn’t have to take in consideration what the absolute perfect, nor what the absolutely worst project would look like. It’s enough to decide the better one of the two that the system suggests. In addition, participants are naturally curious to understand why a certain project has won. Peer reviewing gives them the possibility to overlook other projects and cast their vote for the winners.

The proposals will be evaluated on the basis of the following criteria:

25% – Prototype
20% – Feasibility
20% – Impact/value
20% – Innovativeness
15% – Presentation
Please note that these are the suggested criteria and there may be changes in the percentages or aspects in the different challenges according to the partners’ expectations.

As soon as the evaluation ends on JunctionApp for the teams, we will announce the TOP 8 teams and ask them to prepare for the live pitch. They will have to present their ideas in 4 minutes and after each pitch there will be a quick Q&A session. This part aims to provide a closer insight into these solutions. In the interest of having a fair selection, we only take into consideration the registered teams’ and the partners’ votes since they will have the most relevant opinion and insight into the projects. – Teams as well as the jury will get to vote for their favorite team on JunctionApp and choose the grand winner.

It is possible to win a Challenge Prize and the Grand Prize. The only thing that’s not possible is winning more than one Challenge Prize, since all of teams can submit their project to no more than one challenge.

Online vs. offline attendence

Yes, you can. After you changed your selection in JunctionApp, please notify the organizers about it via

Since there is a limited amount of space at the venue, unfortunately we can not admit everyone. If you get denied, do not worry! You can still participate virtually using our online platforms like Slack and Hopin.

Offline participants are provided with food, drink, coffee, energy drinks, and a merch package including a T-shirt and more! However, there are no showers to refresh, only bathrooms, and although you can stay at night, there are no beds provided, and only a few beanbags will be available.


To submit your project create a 2 minute video pitch, upload it to YouTube and link it on the submission form, along with a GitHub repo. The video can have you talking, a live app demo (if you have one), some cool animation, etc… whatever fits best. Please observe these conditions strictly as in other cases we will unfortunately not be able to evaluate your project.

You can, but please note that one project can only be submitted for one challenge not more!

No. If there is a possibility that the project has already been submitted to another hackathon, CraftHub has the right to disqualify the team from the competition. So please do not submit a previous project of yours to the hackathon to keep the competition fair.
