I think you need to add a lot more context to your question. (IE, edit your submission.)

As an American, who's been involved with both Silicon Valley and Boston startups, I find it rather absurd that anyone here would ever incorporate outside of the US. Likewise, I find it absurd that anyone running a startup outside of the US would ever incorporate in Delaware.

> "especially Indian startups"

Do you mean startups in India, or do you mean startups run by Indian immigrants inside of the US?

Maybe there's something that I don't know?

Either way, you're asking a specific question to a very wide audience. You need a lot more context if you want helpful answers and a coherent discussion.

So, if you're reading this, scroll up and push the "edit" button. Spend a minute or two adding some good context; don't assume that the wide Hacker News audience has any clue what you're talking about.
