This rationale behind relationships like this is pretty straightforward. Banks can't profitably lend amounts below $250k to small businesses, because underwriting a $250k loan costs them about as much as underwriting a $1 million loan. If they can partner with a company that can do it, then banks can underwrite more loans without any increase in acquisition cost.
