What Sigma Squared Fellows say

PowerUs

Sigma Squared is a great place to create friendships with ambitious people. Having a peer group where people support each other and are happy when others are successful is immensely helpful.

Josefien Groot

Co-founder & CEO

Qlayers

Unique community full of inspiring, young entrepreneurs that are ready to make the world a better place. It’s simply amazing to be in contact with likeminded people that are really focused on solutions rather than problems. Self-development is the key to changing your environment and that is why I like the approach of Sigma Squared, where personal and professional development are both viewed as one.
