StickK

StickK is an online platform that helps individuals achieve their goals by committing to them publicly and financially. Users set specific objectives—such as losing weight, quitting smoking, or saving money—and make a commitment by setting a monetary stake. They choose a "referee" to verify progress and can also involve friends or community members for accountability. If users meet their goals, they keep their money; if they fail, the funds can be donated to a charity or an opponent as a penalty. StickK leverages accountability and commitment devices to motivate sustained behavior change.
