Man, I cofounded 3 companies (2 bootstraped & 1 VC backed) and I never expect employees to work 7 days a week. From my cofounders I did expect that when there is really a deadline to hit (usually a big customer changing his specs on the whim, security bugs or infrastructure migration/upgrade) However if "the founder" works less that his employees, you should start looking for a new job right away. This startup most probably won't gonna make it and to swap your limited time to work for them is a bad choice. Even if they pay you very well with investors' money it's best to be in a succeeding company and build the relationships that will give you chances to cofound/rise with the company growth.
