The Sigma Squared summit.

Each year, we host a global invite-only Sigma Squared Summit, where we bring together some of the brightest founders and industry leaders. This year, our summit will take place on October 30th in a hybrid format. Alongside a half-day virtual event, we will unite 100 change-makers at the iconic Learning Center of the Vienna University of Economics and Business Administration. The building was designed by Zaha Hadid, one of the world’s most acclaimed architects.
