I've seen this before so many times, and recommend people quit and sometimes even apply back at their same company. I got my friend a 30% raise after he quit, worked at a new place for two months, it blocked implementation of key projects and the CEO started freaking out. I asked him how much he would pay to fix the problem, and he gave me a number. I said if we paid that as the new salary to my friend we could have him working there in a week. The CEO made the call in front of me lol.
