crowdfunding

 crowdfunding  is the practice of asking people to promise to buy a project, sometimes with a set goal to trigger payments, other times with no set goal, which is generally implemented by siloed organisations, although there is at least one IndieWeb alternative to Kickstarter, one of the most popular crowdfunding silos.
