This chapter describes ShoreBank in Chicago and the network of small businesses that developed around it. These businesses rehabilitated multifamily housing -- and in the process revitalized many of the neighborhoods on Chicago’s south side. For decades, the network developed a robust system of shared labor and financing that allowed each individual business not only to start up, but also to survive the ups and downs of the real estate market. ShoreBank played a central role, both in the development of the network and in its maintenance. Financing was the most obvious form of support provided by the Bank, but it was by no means the only form. Through key personnel, larger strategic choices, and a sophisticated range of community relationships, the Bank acted as the glue that kept the network together. In addition, and critically, the businesses themselves developed a way to share labor with each other, supporting the myriad construction activities required for completion of each building. In 2010, during the apex of the financial crisis, ShoreBank went out of business, and the rebabber network was deeply shaken. Numerous lessons can be learned both from the development of these extraordinary networks, and from their current circumstances.
