HOW IT WORKS

Start, or join a movement, in safety.

Create or join a proposal

  • Your commitment is conditional - it only activates when enough people join
  • Set your own participation threshold or follow the organizer's recommendation
  • Start anonymous if concerned about the risks - your identity is only revealed if the goal is reached
Gain allies, anonymously.

Watch momentum build

  • Share publicly on social media or discreetly within trusted networks
  • See real preferences emerge and track growing support in real-time
  • No obligation until the proposal succeeds
Take action, collectively.

Take synchronized action

  • Act simultaneously with fellow participants
  • Accomplish through group coordination what solo efforts never could
  • Turn individual preferences into powerful cooperation and common purpose
