Sigma Squared is where curiosity, humility and ambition meet. Fellows are dedicated to realizing their vision and sharing their learnings along the way. Being a part of Sigma Squared is the best energizer one can find!

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.

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.
