I feel for you! It sucks when you don't get rewarded but there is something you should realise.
Firstly, what asset are you truly to the company. How much have your ideas meant in terms of actual profit for the company?
Can they do without you? Think of your true seling points in corporate and think about what your ideas have meant in a pure business perspective.
You need as much amo as you can think of before you approach the big wigs. THey might have a lower perception of you than you realise and this could be teh reason you have not been offered a role in corporate at this point. You may need to change that perception and by showing htem a structured outline of what you can offer in corporate, tehy may be super impressed.
Good luck man and let me know how you go!
Your sales angel
