The biggest difference I have noticed: at most companies, a new employee is a body to get done the same work, in the same way, as somebody else. You are defined by how well you execute an already-constructed set of tasks and goals.
At a startup, you are valuable if you add a whole new set of opinions and skills to the team. If you come in and just do what you're asked, even if you do it well, you probably aren't doing very well. You should notice things about the business that are not optimal, blind-spots that the previous employees hadn't thought about, easy ways to save or make lots of money, even though these things aren't part of your formal job description.
Your X factor value is important but don't leave the company with a hole you were brought in to fill.
1. Get things done.
2. Make sure people know you're getting things done.
...and not necessarily in that order either. Being labeled "impractical" is the kiss of death in a startup.
Do those things, and most successful startups won't care about the other bullet points.
...although this probably isn't a ton better. :-)
As someone proposing a new idea, you should find out what the assumptions behind these objections are and why they're considered relevant now. Make someone explain the fundamentals of why something won't work instead of immediately walking away and telling yourself, "oh, someone objected, clearly they know more than I do and this idea will never be good."
Getting into the habit of identifying your assumptions and challenging them also helps you keep a more objective viewpoint over time by helping you to understand accepted wisdom instead of simply parroting it.
I joined an e-commerce team at a major systems integrator and discovered they had left the default password in place for the administrative interface of their flagship implementation.
It was actually possible to delete the entire product database using the website. I changed the password immediately, of course.
I know a carpenter who is looking for the same thing when he hires or subcontracts.
