I agree with what Michael said and would add that the CTO role encompasses far more than just development. A good CTO needs to understand product management, business development, and sales. He or she has to be able to present to customers, partners, investors, and the board. Managing a growing team is also part of the role, as is balancing business and technical demands. It's possible that your PHP hacker co-founder can do all that, but your VCs just might know someone more qualified.
