We're currently working to boil all that down and bring it right out in front to fix this problem. Basically what happened here was this version of the home page was somewhere between a teaser and functional homepage. We've been working on so many other parts of the business, we let one of the most important pages slip. We're hoping to fix this with our new design coming out soon.
"Get funding for your software project from early adopters who care. Ramen lets you raise money from users who help test and develop your product."
Your homepage lacks clear instructions for either startup projects or investor/users. Have a clear look at the frontpage of ramen.is from the perspective of a user, then look at sites like YouTube, Soundcloud, BBC iPlayer, Kickstater and so on. These are all trying to seduce people in to look at things that are new and fresh.
Then look at it from the perspective of the startup entrepreneur. Business users want to see both clear instructions on how to use the site and what they'll get out of it, as well as seeing activity of existing projects, case studies of companies that have used it before.
You aren't doing that good at providing either.
Just some constructive criticism, I hope. Interesting project.
