Ask HN: Banking services for startups?

What sort of banking services are needed or recommended for startups? What sort of banks should startups be looking for? Small and local, or big and national? Any particularly good or bad experiences to share?

In my case, when I incorporated the business I opened an business account at a local credit union. But as I head toward generating actual revenue this year (enterprise SaaS), I wonder if there are things a larger bank could do for me that my credit union is too small to handle.
