Every startup is different. They differ in expected working hours, stability, compensation, equity, impact, mission, etc. Imo, most of these dimensions overlap with bigger corps. except impact: it is much easier to have a lot of impact at a startup.<p>Some of the other commenters have mentioned startups with low stability, low equity, low compensation, and high expected working hours. I wouldn't want to work there.<p>But I am at a startup with 40 hrs expected / week, good compensation, high impact, and medium stability -- that is a good tradeoff for me.
