Every week goes by and investment industry professionals read more and more about the growth in the marketplace lending industry. Sure, it can become a trillion dollar market by the people.

Check out my article on Forbes that explains how this quiet acquisition can fill the missing void of engagement in the marketplace lending industry and truly take the promise of peer to peer lending to the next level.
