Unfortunately, Yelp does not explicitly state eligibility nor requirements to be an Elite user. Users can only self-nominate and hope for the best.

LendingClub - Visualizing Loans And Building Investment Models
LendingClub is a peer-to-peer lending company, offering loans with fixed interest rates and equal payments. Each loan is broken up into many Notes, which corresponds to a fraction of the overall loan.

Can we maximize returns by building an investment model that predicts loan status, whether a loan will be fully paid or default?
