**Abstract:** This paper investigates how public sector institutions change their form and approach to achieve a socially innovative urban governance. The "Mayor's Office of New Urban Mechanics" (MONUM) in Boston, Massachusetts (USA) proves a representative case of innovation in the public sector. As a new type of government agency, it is essentially an open innovation lab dedicated to innovative evidence-based policymaking. Following a new dynamic organizational pattern in urban governance, MONUM is conducive to project-oriented social innovation practices and horizontal multi-sectoral collaboration among the three societal sectors: public, private, and civil. Its results suggest that first, the peculiarity of MONUM lies in its hybrid and boundary-blurring nature. Second, new institutional forms that experiment with urban governance can rely on multi-sectoral collaboration. Third, MONUM has experimented with a systemic approach to social innovation following the "design thinking theory." The MONUM case can contribute to the current debate in Europe on the need to harmonize EU policies for an effective social inclusion by promoting the application of the place-sensitive approach.
