I found mentorship was much better at startups than at larger companies (and if anything the culture of trust was better), and having broad responsibility for delivery is a lot more fulfilling and educational than working as a small stage of a corporate pipeline - in theory that might give you more chance to do deep focused work, but in practice it tends to just mean more waiting around.
I agree with the last advice: take a lot of salary, don't work more than 40 hours/week - and I'd also add make sure you know your legal rights, as a startup manager may opt for the kind of blatant illegality that corporate HR would stomp on in a larger company. But when you set the right limits startups - not every startup, but the right startup - can mean decent pay and a much better work environment than a megacorp.
