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, we will unite 300+ change-makers at the iconic Nova School of Business and Economics in Cascais, Portugal on October 29 & 30.

At our summits, you will get an early sense of emerging trends by meeting those who build the technologies and solutions of the future. And you will form long-lasting relationships, on both a professional and personal level.
