LoanStreet is the first fully integrated, online platform that streamlines the process of sharing, managing, and originating loans for credit unions, banks, and direct lenders.

Our Mission is to provide the most efficient, transparent and robust tools for financial institutions to manage loans, connect with partners, and effectively share risk.

LoanStreet was founded in 2013 with the mission to create a more efficient, transparent, and robust way to connect lenders and investors as well as automate the administration of their loans.

Today, hundreds of financial institutions rely on our turnkey, online platform to gain access to a nationwide network of lenders and investors, track the performance of their loan portfolio, and more profitably grow and diversify their balance sheet.

LoanStreet was co-founded by Ian Lampl, the former U.S. Department of the Treasury Deputy Chief Counsel for TARP, where he oversaw critical financial institution transactions during the financial crisis.
