With this comment, I lost any faith in this idea as it's clear this is not about both sides deriving value in the process. In your scheme, startup "founders" or really wantrapreneurs get to try out half-baked ideas by giving away worthless equity to folks that are ultimately being duped while idea guys ultimately talk about their MVP and pivots and other bs that people who fancy themselves as startup founders think they should talk about.

On a related note, the "founders" participating in sites like these give a bad name to business people with legitimate biz building skills.
