How many pre-signups before launching my crowdfunding campaign?

I posed this question over on reddit and got an interesting response.

“A crowdfunding campaign, in itself and providing you manage it properly, will attract sign ups. Based on my own experience, I now use this rule: 1/3 of the funding goal, based on the expected average pledge.

If your goal is 25k for a $25 average, then (25’000 / 25) / 3. So roughly 300 sign ups.”

 

If this is true, and you need $25k then you could perhaps expect to be 100% funded on day 1 and end up with at least 300% at the end…. right?
