So to be clear, you have no coding, development management, or business skills. You have no funding, investment, or seed capital. You want to “hire” a developer by paying them nothing.

Additionally, you want to be sure they sign an NDA in exchange for nothing.

The question isn’t “how can you prevent them running off with your idea?”, it’s “why would any developer want to work with you?”

Seriously, bring something to the table. You know how every cab driver in Hollywood has a screenplay? Every would-be Travis Kalanick has “a great idea for an app”.

Learn to code, make an MVP, start earning cashflow, produce some projections, find some more money, then worry about hiring someone to do it better.

Why don’t you buy a reasonable used car, take care of it, and then sell it on at the end of your trip, you wasteful, thoughtless moron?

Nice try, David Tolley…
