When startup founders ask for an NDA before talking to you, that's another red flag.

So they have another full-time job, and they're doing this on the side without full-time effort? You're the startup's only full-time employee?

Without full time effort correct. They have demanding day jobs.

First full time employee. They are hiring a server side dev, UX, Design and QA.

So they're financing it out of the money they earn in their regular job?

It sounds like they have a startup hobby rather than taking it seriously.

It sounds like a dead-end to me. They're going to blow through 3-12 months worth of expenses, realize they have nothing to show for it, decide to stop wasting their money, and shut it down.
