Young and creative contestants showed off their tech talents in a quest to create the next shared economy service with eBay & Mjølner.

Our hackathon united IT professionals from eBay and Mjølner with enthusiastic students in a four-day race to invent the next big shared economy service. The event took place in Aarhus, from April 28th to May 1st as part of the first annual festival, Internet Week Denmark.

The hackathon fostered three prototypes that all had the customer, user, and business model in mind.



We kicked off the event with an innovation workshop for 35 pupils from Hestlund Efterskole, representing the target group: 14-19 year-olds.

The students formed five groups and with exercises such as Six Thinking Hats, Empathy Mapping, and Storyboarding, they came up with five strong concepts. The students then further developed the concepts. Finally, three groups were formed and an intense three-day hack commenced.


“We were quite impressed with the students. They had many great ideas and were able to narrow them down to strong
concepts ready to hand over to the developers.”

The workshop clearly showed that the main issue for target users was trust. The three hacking groups chose different paths to address the issue.


  • Team 1: Andrei Git, Cristian Sarac, and Dragos Barbu built a locally anchored platform.
  • Team 2: Anders Fauerholdt, Christoffer Bech, Theis Nickelsen, and Kristian Jørgensen developed a cross-site rating system.
  • Team 3: Jørgen Heinsen, Khaled Saied, Jonas Pedersen, and Aleksandar Peev created a video chat extension to



After three productive days, the groups presented their prototypes for a jury of eBay and Mjølner experts. Rate28, the cross-site rating system created by Team 2 won the competition.


“Rate28 is a simple, but very effective solution with great potential. That’s why they are the winners. The event has proven that a hackathon is a great way to tackle real life challenges and we strive to be back again next year.”

– Flemming Laugesen, CTO of Ebay Denmark
