Hello there,

For crowdfunding platforms you need to look at your idea from different perspective. there are a lot of things which need to be considered, from agreement sections that decrease number of scammers who join your website to UI and UX. Here are some friendly advice:

1 - There are big competitors like kickstarter and indiegogo out there in this market so you need some type of special difference to make your platform unique to be able to compete with them

2 - Make a targeted community on social networks(I can help you with that if you want) to have a marketing pool

3 - Try to find some innovative ideas to start your platform with them or start it with your own ideas

If you need any help or have further questions, please do not hesitate to send me a message here
