We had a similar issue.
Assuming all 3 co-founders are American citizens I can think of two banks: Everbank and BofI. If your co-founders are merely living in America but not citizens, BofI is out. Everbank however will still allow you to bank with them but you might have to jump through some hoops.

In our case we have people worldwide. We still don't know a good answer to that question.

I would definitely suggest Silicon Valley Bank. You can take care of most of it remotely, and it's 100% startup friendly. Plus, it's going to be the best bank to have if you ever raise money.

Actually, Stripe is launching a new program where they help startups incorporate, do all the initial paperwork and open up an account for $500. https://stripe.com/atlas
