I did the same , I won't name the company, but it was a well established company.
They were offering only 30% of current CTC , I told I already have a offer of 50% from the Current CTC.
I tried to convince but they didn't ,I was a strong hire and they required smone like me with a skill set in their team.but they didn't raise the offer
Later I joined a product base company ,which gave a very good offer I couldn't refuse.
And to my surprise after I joined there ,the company x which previously hadn't raise the package came to with double the offer what I was getting at the product base company.
But I didn't join that, thought it could have been easy for me ,but I wanted to keep my loyalties and ethics straight,and money automatically will follow.
And being loyal and showing ur domain knowledge,actually have me at double the salary what I was initially hired for in 2 years.
@Paul I would say find a company that see's ur talent and admires u and ur thoughts . It should be like a 50-50 partnership,like a win win situation for u both.money will follow automatically.hope that helps....😄
