The platform represents a two-sided marketplace that, on one side, provides hassle-free access to an asset class that was previously inaccessible to individual investors: short-term, real estate backed loans. On the other side of the marketplace, PeerStreet connects a vetted network of private lenders with diverse sources of capital to help fuel their growth and bring lending back to their local communities.
