> At my startup we currently have 2 classes of shares. Class A is a "super voting" share with 10 votes and Class B is a common share with 1 vote. Pretty standard nowadays.

That only works if your CEO is a superhero. Just because Ford, Google, and Facebook did it does not mean you can.

There was a time when the NYSE wouldn't list a stock with more than one kind of share, but they caved on that some years ago due to competition from NASDAQ.
