In their own words

Yet, most of us struggle to achieve our goals. That’s because there’s a big difference between having a goal and achieving a goal—stickK works by helping people eliminate this gap by using, what we call, a Commitment Contract. A Commitment Contract is a binding agreement you sign with yourself to ensure that you follow through with your intentions—and it does this by utilizing the psychological power of loss aversion and accountability to drive behavior change. By asking our users to sign Commitment Contracts, stickK helps users define their goal (whatever it may be), acknowledge what it’ll take to accomplish it, and leverage the power of putting money on the line to turn that goal into a reality.
