1) 70-80% of your funding, unless you’re a rare breakout viral sensation, will be raised in the opening and closing 48-72hrs. The middle will be a slog. Be ready for that and just keep communication/promoting going.
2) It’s relatively easy to clear $2500-$5000. Not EASY, but relatively easy. It takes a lot to justify people to push you to $10,000+. You HAVE to get beyond your friends/family/immediate network and that is very, very difficult. You need to do a lot of prep, host events, and get people blasting this thing everywhere. You need to shamelessly shake EVERY tree you available no matter how distant they are.
3) People invest in you as much as, if not more than, your product. The video needs to feature not just the product/idea (having a functioning version helps a lot btw) but YOU. People need to like and trust you. This is no different from investors. Good luck!
