Junction (hackathon)

Junction is a hackathon organizer with headquarters Espoo, Finland. Started in 2015, Junction grew to be one of the largest organizers in Europe. In 2018 it expanded globally with a Junction event at Tsinghua University in China and cooperation with Chinese and South Korean universities bringing high performing students to attend the event in Helsinki.

As always, the teams had 48 hours to work on their projects, with the event ending on Sunday with a demo expo. This year, the winner of the 20 000 EUR main prize was appointed using a new judging process. An open source technology called Gavel was used first to determine the finalists from each track. Then, a panel of expert judges inspected each finalist in delicate detail, even going through the project's code repositories.
