Completely agree with Hyperstarter here, especially with your rewards.
Before you go into your crowdfunding campaign you need to make sure you have:
1. Found and captured a large enough audience for the project. This audience must also have buying intent
2. Conducted a pre-launch to get people ready for the campaign launch
3. Created a converting campaign page with tons of social proof
If you haven't completed all 3 of these, don't expect to get funded because well, the biggest myth for crowdfunding is that if you just launch to the millions of people on the crowdfunding platform, they will all just come and give you money.
With the rewards, here are the things to consider when creating a rewards strategy:
