Startups are challenging - unless there's a lot of financial backing.

Spend the bucks and get a qualified immigration lawyer instead of asking for fee advice on a public website!
Probably I'll get in trouble for saying that. (I don't mind giving fee advice to people who probably don't have the money to hire a lawyer, but when you use the word "entrepreneur" I assume you mean someone who is in the business world and knows the value of a good lawyer (especially in the IT business world).
Consider an E-2 Treaty Investor visa.
