The Kickstarter model doesn't work for consultant. It's about wants vs. needs: the kickstarter model is for wants, consultants are for needs. If I pledged to a kickstarter project to buy yet another iphone case and the project failed to launch, I'll just have to make do without yet another iphone case. No big deal. If I need to hire a consultant to build an e-commerce website or to set up a payroll system, I need that to happen no matter what. I can't wait 21 days only to find out the consultant never gets enough pledges to "launch." Then what? Pledge to another consultant, wait another 21 days and rinse and repeat?
