This is a ridiculously awesome business idea. Either you'll make millions or nothing with that. But the costs aren't that high, and at least the buzz can be used for something else. Good luck!
That's the thing about business ideas where revenue is directly tied to the work you have to do: scaling is super easy. getting more questions than you can handle by yourself? hire some friends to help.
>"After you pay $10, I'll email you to start the conversation. You then share whatever it is you're looking for feedback on, and I'll tell you exactly how I feel about it. Most submissions are handled within a few hours, but some might take up to a few days. All submissions are completely private." //
Assuming he is an honest actor in this process he can't share your submission with anyone as then they wouldn't be private. It is specified that it is he, Jordan, who will email you, he will say how he feels.
It could have been set up differently to allow for scaling but part of the drawn I think is that it's a real, named and identifiable, individual that you are contacting.
Of course "Jordan" could be a made up person and this could be a way to gather information for social manipulation or straight-out blackmail, but you know ...
In this case I would agree, probably relatively easy to scale.
I've long thought about the differences in scalability and margins when comparing service-based businesses to product-based ones.
In the ad agency world, it is all service-based for the most part still, margins are razor thin, pay is low, and the stress is massive. The problem then becomes maintaining quality of service as you scale, and efficiency of operations to keep your margins as healthy as possible. Stressed out service employees are basically the equivalent of delivering a shitty product. If it becomes a big enough loss in quality, you lose customers.
