To expand a bit on @blaineri's thoughts, the role of CTO encompasses both internal technical leadership and external technical representation functions. To work, he needs to delegate his internal technical leadership responsibilities to a VP/Director of Engineering, listen to his technical staff, and be capable of representing the technical aspects of the company competently to customers, partners, and investors. If these three conditions are in place, there is no concern. Otherwise, run, don't walk, away.
