From food and drinks to keynotes, workshops and satellite happenings, for all your needs and purposes, we got it. 
Keep checking the schedule for changes and additions to our hectic program for the weekend!

Hackathons are all about taking something you love, combining it with tech and learning something in the process. Junction brings together hackers, designers, the coolest partners, and hardware for one weekend of hacking. It’s a place where creators can let go of their inhibitions and create cool inspiring projects.


Junction is not your standard cafeteria hackathon. Junction is meant to be seen, to be heard, to be felt and most importantly to be experienced. Held annually in the cold and slushy Helsinki of late November, Junction is bound to be an unforgettable experience. In 2015 Junction was built inside of an old abandoned boiler hall. In 2016 it was organized at a 19th-century shipping warehouse right next to the sea in Katajanokka, Helsinki, Finland. In 2017 Junction will be organized in the prestigious Dipoli-building at the Aalto University campus in Otaniemi, Espoo. This uniquely beautiful building is one of the finest examples of Finnish architecture.


Junction has grown to become Europe’s biggest hackathon and an embodiment of the blooming startup ecosystem of the Nordics. But that’s not all we are about. We know that the future is not created by individuals, it’s created by communities, ideologies, and beliefs. That’s why Junction is much more than an event, it is an ideology, a movement with the goal of inspiring and fostering a community of creators. At Junction we believe a fun open-minded environment, innovative industry partners, and a little bit of passion is the beginning to creating a better tomorrow.
