Our take
Prosper is a peer-to-peer lending platform, that connects investors with borrowers directly. When it launched in 2005 it was the first of its kind and paved the way for the now crowded peer-to-peer lending market, which includes competitors like Peerform, Upstart, Funding Circle and LendingClub.
The company provides an attractive option by cutting out the middleman and making applications faster, meaning that socially and financially rewarding investments can be made. Prosper is one of the largest and most recognized in this industry, having facilitated billions in loans to over two million borrowers.
In more recent years, Prosper has forged ties with banks to allow it to launch its home equity credit line, indicating a new direction for the company. It continues to develop its offering and remains a force in the market, with no reason it won't continue to succeed.
