IANAL either (although I do date one), and I too have heard of these things. I think they are called E-2 visas. They require you to raise or invest around $100k in a US business. The lawyer who told me about the E-2 was quick to warn that the applications get scrutinized hard. It sounded political, vaguely sketchy, expensive, and complicated.
it's kind of complicated, whatever process you choose. email me at gustaf@gmail.com if you want help. I'm from sweden and our company got funded by Y Combinator in November.
