OUR MISSION


Challenge accepted! is a smartphone app that allows you to challenge your friends, colleagues or family to do good. It serves as a platform, where everyone can upload sustainability-related challenges, set themselves goals and share their success. The challenges can either be within a group of friends, or public and thus open for everyone. In this way, CA! provides an easy try-out of low-impact lifestyles with tips, scorekeeping and social activities.

Our mission is to convince people that each one of us can contribute to the reduction of our overall impact by changing our habits gradually and without lowering our standard of life. Next to a more sustainable and healthy lifestyle, the value for our users lies in the interactive and informative solving of challenges and in the acknowledgement they receive via sharing their success on social media.

WE CONNECT SUSTAINABILITY TO FUN, SOCIAL INTERACTION AND COMPETITION
