Based upon some completely unscientific asking around, it seems like a person who has an employee number under 10 is likely to make 1/50th to 1/400th of the total exit after taxes. So $100mm for the company = $500K plus or minus. Not total crap, but also probably not worth it based upon the money alone.
The reason to work for a startup as an early employee is the fun (if you like working 12-14 hour days on cool stuff) and the experience. I'm guessing having a successful startup under your belt makes it a LOT easier to get your own company funded down the line. Also, people can end up much higher in a large organization earlier than they could have without some serious corporate climbing.
Is the 12-14 hour thing necessarily true? I know some people at startups and they don't work that much. It seems that a lot of startups say they value life/work separation. There has also been research to suggest that working that much is anti-productive. Of course, I understand crunch time, but as a rule 12-14 hours a day!? That seems a little outrageous.

Of course they say so. Deloitte says so too, and Wachtell, and Cravath, and every other high pressure professional outfit. Doesn't make it true.

Yeah but most of those are in different circumstances. It all depends on where the motivation comes from. If you take a wage slave and whip him into working 80 hours, while paying for 40, and not dangling any form of carrot in front of him/her (making partner), of course productivity will go down. If you've got a product you believe in, a vision to make it come true, an innate drive to succeed no matter what, and no personal life, you can work 80 or 100 hours a week for months on end and get the work of 5 or 10 people done in that time.
