I think you need to know things about both yourself and the company before you can make a decision like this.

Questions about yourself: * Are you willing to sacrifice your free time and family time for your job?

* Can you get things done, even if it's not so clean?

* When crunch mode hits, how will you keep yourself centered? (e.g. exercise)

Questions about the company:

* What is the expected work schedule, and does it fit your life?

* How are they funded, do they have a revenue stream?

* What is the 1, 3, and 5 year plan for the company?

* Does your compensation include equity?

Hope this helps,
