I think the biggest difference between startups and established companies (even those that try to emulate a startup like culture) is the hunger for success. Established successful tech companies have already accomplished amazing things and may have cornered or even created the particular market they're in. They typically have several early employees who have made a fortune and many employees who are fairly well off from the company's stock purchase plan. Bill Gates lamented the fact that one of his employees wasn't quite as motivated as he used to be in the following quote (paraphrased): "something about a man changes when his net worth surpasses $100 million"
