Don't do things for the money solely; do you like to work in a startup, long and hard hours, knowing that they might belly-up when the startup-bubble bursts for a measly 14k extra? You can of course ask your boss for a raise anyway, that's usually a good plan if you didn't get one for a while.

It's important to consider stuff like: is this enough career advancement, do I need the money etc. Getting jobs for more money is not that hard if you would be looking atm, so other considerations outweigh the money.
