I was mainly descriptive. "LendingClub is a peer-to-peer loan platform which matches borrowers with investors and underwrites the loan process... Removes unnecessary costs... Improves transparency..." The interviewer mentioned some previous candidate responses as 'the uber of loans' or 'the Facebook of lending.' To me, it seemed like he was generally not very impressed with that sort of knee-jerk, one liner response. Try to dig a bit deeper.
