stickK

stickK.com is a U.S.-based internet startup company that enables users to create custom contracts.

stickK.com is the product of three Yale University economists who believed that using contracts could be an effective way to help people accomplish their objectives. Users can create contracts around common resolutions (weight loss, stopping smoking, getting exercise) or create custom contracts. Depending on the contract, stickK.com users can put money on the contract, penalizing themselves financially if they can't come through as delivered.
