Main piece of feedback is: MISSING CALLS TO ACTION!

I thought the only call to action which is confusingly enough linked with an image "Connect to stripe" was just a sample image, it took me going back to your landing page three times to realize it was not until I saw the URL it linked to. Definitely not clear enough!

Another issue is the main issue with the idea itself, it might be wrong, but who would use this? If an application has enough buzz (like mailbox) trying to monetize the waiting list might seem tacky, and they probably (and do) have enough resources to not care about the money they could take for waiting in line.
