This was ViennaUP 2025

Phew. ViennaUP 2025 - what a ride! We couldn’t have done it without the support of our amazing programme partners, our sponsors, and, of course, all the fantastic participants. 

This year, we welcomed 15,000 participants from 95 countries at more than 69 events across 45 locations in the city… wow! Together, we truly lit up the Viennese startup ecosystem.

Want to relive the magic of the 9 days? Head over to our gallery – and if you share any festival snapshots on social media, don’t forget to use the hashtag #ViennaUP. 

We know you're already chomping at the bit for more networking, collaborating, inspiration and changemaking, and we can't wait either! Good news: ViennaUP will return in 2026:
