I only really see it used on potential employees, rather than potential customers. It sounds better than the more-correct 'come and sacrifice your best years on this pointless app that might make me rich but probably will crash and burn like all the others'.

That's definitely something which you can tell employees if you're making an app like that, but it's tolerable to use on customers too, in a pinch.

They probably won't believe you, but it's better sounding than nothing when features and tangible results are sparse.

And hey! When all else fails, it's at least guaranteed to not be false advertising.
