'Startup' doesn't necessarily imply 'technology company'. For example, some run-of-the-mill restaurant certainly isn't a startup in my opinion but a brick and mortar store offering a unique product or concept could very well be considered a startup.
One could in fact argue that the most influential tech companies are located in Silicon Valley. However, in terms of sheer numbers I daresay most startups are actually founded outside the US. Just consider the huge amount of medium-sized enterprise IT companies that offer some essential service or product that no one probably has ever heard of. I'd certainly consider those to be startups (when they were founded, that is), not of the sexiest variety, but startups nonetheless.
