Assumption alert: the account at the partner bank is in your name.
Your money must be in your name for it to get the FDIC's "$250,000 limit per depositor" insurance coverage. Having one big mattress with Simple's name on it would preclude your money being insured. Ergo, the account must be in your name.
I dont' think that's exactly true. There is such a thing as the CDARS program, which allows you to spread your money between accounts at multiple banks. Not sure what the limitations are on that, but I would be weary of assumptions on this.
If the money were not in my name, that would be deal killer.
It's per depositor per bank. Not per depositor period. Spreading your money across accounts at a single bank would not get you additional protection. Spreading your money across banks is how you protect more of your money.
