Aside from the frequently mentioned aspects that many times SVB is the only reasonable place to even get an account if you are a startup (something that is changing now thanks to things like Mercury and Brex), many services will push you to use SVB, outside of VCs. For example, accounting and management services like SVB for the simple reason that SVB has basic features like "user groups with different privileges, so that some people can issue wires but not approve them, etc." BofA small business is really hard to work with. Some of it sadly comes down to super basic stuff like that.
