Get feedback from readers

So I have many friends that have created online courses and books and softwares and one of the biggest pain they had was not having early feedback.
On the other lots of my friends love to read, watch or use products that is useful to them and if it's free even better.
The idea of feedback stars is to bring creators and feedbackers together.
Creators give away free access to their content to limited number of users which will pay for it with their detailed feedback.
Initially I was thinking to focus on tech topics (like programming) as it's my main field.
When you signup in the landing page you will receive an email asking if you are a creator that wants feedback or a feedbacker.
I would really appreciate your feedback as this is the first time I'm trying to launch an idea without much preparation!
