I had a look at your first discute site. The rimbaud site errored out. If I had the skills in your chosen tech stack (which I don't) my first question would be "show me your business plan". As a rational person, I would be looking at "my" probable return on "my" investment in time and effort into "your" idea. In other words, an evaluation of opportunity cost. Most competent technical potential cofounders are either earning a good income or working on some idea that will produce a considerable multiple on their recent income. In either case, your proposal would need to be more attractive than the alternatives available to them.
