Most of these sites will go down due to one big hurdle. Payments. Underwriting merchants and get verified by Visa/MasterCard as a payment service provider is a bitch. Aggregating credit cards is a heavily regulated area - but most of these sites are unaware of this issue. We initially started on Stripe, and got told what we were doing was unregulated/not allowed on stripe, so we then grabbed a coffee with them and learnt about this process. In fact I was grabbing coffee with Sahil (Gumroad) a few months ago and they've just run into this issue themselves - which they are starting to solve. so you'll probably notice them asking you for more information to underwrite you, unless they find a way around this. That's also why we ask users to go through an activate process.
