Given the offers I've heard people getting from early stage startups (engineer 2-5), I don't really get why someone would join them. Below market rate salary? 0.1% of a company that's going to exit at $80M with a 10% chance and $0 with a 90% chance? That comes out to $80k over four years of work, before taxes, in the typical successful case, which is itself atypical. And for what amounts to a relatively small bonus, I'd be expected to work 50-70 hour weeks? Sign me up!
