Outsourcing can be hugely dangerous for startups. I have talked to the founders of several startups who were domain experts but not professional developers. They usually ended up with a product that they couldn't release. Part of the problem was that the founders were not sufficiently technically skilled to communicate their vision across the language and cultural barriers. Another was that they usually ended up with an unscalable MS stack. To be fair, that's pretty common, if you use less skilled US developers.
