Causes was founded with the mission of empowering anyone to change the world. Our model is based upon the belief that everyone has the power to have an outsized impact on the world by banding together with other like-minded individuals, taking direct action, and inspiring their friends and their friends' friends to join in.

People can care about changing the world. But what gets them to act is pressure and social reward.
