How can I figure out how much I could potentially raise?

First, look at your network (social media and beyond), and come up with a number of how many people are in it. Then, multiply that by the amount you think you could raise from each person. Then you’ll have the figure of how much your total network is potentially worth. This is a good place to start, but base your funding goal on how much you need while also taking into account the per transaction fees.
