Pros: for even the worst startup there are fewer useless people, bureaucrats and insane witch hunt types than there are in a large business. You learn more if you're a go-getter and your work can really make a difference. Cons: your returns are way more volatile -CAPM adjusted, I'm pretty sure it's not worth it, and if you're trying to learn things and need formal mentoring rather than 'self serve' you won't get it. I can't stand bureaucracy and non-contributors with power over my life, so I prefer small startups.
