Has he worked as an early employee in another new company before? Because all of the best founders I know have. (Zuckerberg is an extreme outlier.) Experience will save you a lot of heartache. I'm learning so much at the startup I'm currently working at, just by witnessing how decisions are made, what tradeoffs need to be made, etc. These will all be invaluable if I ever start my own company, and yet I never realized any of this until I accidentally ended up working for somebody else.
