Maybe this is just because of my lack of business experience, but I don't really think a pre-revenue company particularly needs a full-time CEO; until you've managed to make something people want, the challenges are primarily technical.
Now however I'm wondering what a startup CEO actually does. Still not going to apply for the position but thought it would be interesting to solicit information here as to what qualities are needed for a startup CEO.
A distinct lack of a criminal record.
Sociopathic Tendencies.
Enough smarts to hide the sociopathic tendencies.
A fanatical adherence to the idea of projecting an image of ethical probity.
A deep dark secret that I can hold over him like a damocletian sword.
Or not. Realistically a CEO needs leadership skills and a keen sense of what tasks are better handled by other people; everything else is optional.
Passion for the startup, and ready to spend 18 hrs daily - if needed - just for the sake of making the startup in a leading position.
But the problem that you won't be sure if the applicant for the CEO job really has these abilities or not. You can know it, only if he/she has a history record!
