It's just a group of astonishing and extraordinary individuals. Being part of that community and having the opportunity to exchange with each other is just amazing.

Josefien Groot

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.

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.
