What is stickK?

stickK is a goal-setting platform built around Commitment Contracts: you name a goal, set a timeline and report on it daily, weekly or once at the end. A Referee can verify each report, Supporters can follow along, and you can put money at stake that is charged whenever a reporting period fails. It was founded by two Yale professors and a Yale management student, and it runs in a browser and in iOS and Android apps.

stickK has a free plan. See every plan

Good for

  • People who follow through when money or reputation is on the line
  • Goals that a friend, coach or family member can verify as Referee
  • Clubs, teams and workplaces running a shared challenge as a Campaign

Worth knowing

  • stickK keeps 50% of forfeited stakes sent to an anti-charity, plus contract costs, under its contract terms last updated June 12, 2024.
  • Those terms removed a $5 creation fee and ended charity and friend-or-foe recipients for new contracts; older help articles still describe all three.
  • A contract cannot be deleted once it begins; the terms allow cancellation only with a physician's medical excuse form.
  • Prices for the paid Campaign plans (All-access and Pro) are not published in the help center; they appear inside a Campaign admin account.

Key features

Commitment Contracts
A contract with yourself that fixes a goal, a start and end date and a reporting schedule. After creation you can only add a Referee, invite Supporters and change its privacy settings.
Reports on a fixed schedule
You report success or failure daily, weekly or once at the end. A report not filed within 24 hours (daily) or 72 hours (weekly and single-report contracts) counts as unsuccessful.
Referees
A person you invite verifies your reports and has the final word: a Referee can turn a reported success into a failure. Without one, the contract runs "On Your Honor".
Money stakes
Set an amount that is charged to your card within 48 hours of each unsuccessful reporting period. Under the June 2024 terms, new stakes go to an anti-charity you pick or to stickK itself.
Supporters and Commitment Journal
Supporters can be emailed your result after each report and can comment in the Commitment Journal, where you add notes and progress photos.
Communities and Campaigns
A public contract can be listed in up to three of ten topic Communities. Campaigns bundle a set of contracts for a group, whose members join with an activation code.
