Well, that's sort of the name of the game with startups.

It also speaks to though that perhaps getting new feature in front of your users sooner should be a goal. For instance, you can quickly make mockups with something like InvisionApp.com and then throw those in front of some users for feedback. If it's not working you can shelf it. That way you don't spend development efforts on features that your users don't find useful.
