As I understand it, Bancorp is just contracted by Simple to hold the funds and interface with the banking system. All of the policies, support and user-facing parts are handled by Simple itself.
Actually it's the other way around. Simple is the public facing interface that is beholden to all of the policies and inconveniences of Bancorp. Don't get me wrong I love the service but full disclosure it's Bancorp with makeup. Now I have had instances where they where Bancorp was closed for a holiday and my direct deposit didn't get processed and I had bills that were going to hit that I needed access to my funds and they were very helpful and happy to do a temporary credit to my account to make sure that I got what I needed.
