The world is shifting toward smarter, greener, and more sustainable solutions — and Vaasa is leading the way. That’s why we’re bringing JunctionX to Finland’s energy capital for a 30-hour hackathon like no other.
JunctionXVaasa, happening 27.–28.9.2025, is your chance to reimagine the future of energy, sustainability, and technology by building real solutions with real impact.
