Anarcho-Capitalism and Shareholder rights

I am a bit confused on how Corporate governace whould work in an Anarcho-Capitalist system … to not fall into the Tyranny of the Majority thru voting . Maybe board proportional representation ? Maybe for Mergers and Acquisitions it ia easier for no one can force you to sell the shares and you will become a minority holder in the new corporation … but how about corporate strategies and managemant ? Thank you very much .
