"LendingClub doesn't loan out its own capital and collects fees of loans that are originated on its platform from both individuals and more sophisticated investors alike."
Lending Club owns a subsidiary fund that invests in the platform as well.
Investors should be aware that LC is both a platform, and an investor in it's own platform which, if not monitored closely, can be potentially dangerous.
