About

CapStack is a fintech startup developing an integrated operating system for banks to facilitate collaborations between financial institutions, primarily in the U.S. The platform provides banks with visibility into one another's portfolios, helping them foster cooperation, enable asset diversification, and enhance profitability. The company aims to address gaps around loan and deposit exposure, portfolio diversity, and risk management by creating a unified, digital marketplace for loan trading and collaboration. CapStack's platform allows banks and credit unions to buy and sell whole loans and loan participations, breaking down geographic, operational, and data silos.
