I'm guessing they will say they raised some money (equity) to fund expansion.
They've gone back and forth on the size limits for investments. This latest limit is 5% of a loan, which will cause difficulty for larger investors. I explained to them the Prosper scheme of limiting any one investor to 10% until the loan has been sitting in funding for 1 day, at which time the limit is automatically removed, and suggested that they might do something like that.
