Please note that whether or not this is a good thing for Prosper's bottom line is currently unknown.
All of Prosper's financial filings with the SEC have shown that they have classically been unable to properly scale their revenues with their expenses. In nearly every single filing, even as Prosper's originations revenues increased, their expenses increased dramatically more.
Note that Prosper's quarterly losses have continued to get high and higher by significant percentages even though they keep increasing their originations revenues.
Past performance is not necessarily indicative of future results, but it does indicate that it is not a truism that increasing revenue increases profit.
It is possible that the new management has been able to make changes to Prosper which turns that expense scaling trend around, but there hasn't been any evidence to that case in the 2013 Q1 and Q2 filings. Maybe Q3 will be different or maybe it won't. We will just have to wait and see.
