Last week, we once again experienced what so many of our Fellows describe as their favourite moment of the year. ❤️
400+ founders, investors, and industry leaders from across the world came together in Vienna for the Sigma Summit 2026.
It’s hard to put into words just how special this week was. And none of it would have been possible without the incredible people who made it happen.

A big thank you also to our workshop hosts - Robin Wauters, David Rowan, Philip Stehlik, Matthias Strolz, Andrew Thompson, Mirko Caspar, Xavier Sarras, and Daniel Dippold - for making the second day so engaging, interactive, and thought-provoking.

📸 To our media team: Thank you for capturing the big and small moments that we’ll get to look back on for years to come.
And what a year to celebrate five years of Sigma Squared Society! Five years of friendships, collaborations, companies built, and countless stories that started within this community.
