This chapter examines how policy innovation cultivators worked, in an attempt to institutionalise co-created innovations in the city. Reframing the Lab’s agenda towards a green and wellbeing city, they mobilised civil society networks and secured vertical support from national agencies and municipal leaders. Acting as discourse agents, particularly by using boundary-spanning tactics, they bridged actors, resources, and rules to embed co-created proposals within formal institutions. Two cases demonstrate the approach: green innovations for the century-old Rubber Tree Road, coordinated across seven municipalities and the provincial tier, and the creation of a city Food Council to drive inclusive food policy. Employing empathetic policy design in empowered deliberation, and applying a critical lens to design thinking and futures thinking, the Lab centred disadvantaged groups and fostered emotional connections, which helped advance co-created ideas into piloted projects and embed them in formal rules for a more inclusive and sustainable city. However, the practices revealed that, even when formal collaboration—with written agreements—was secured with the municipality, scaling up and embedding co-developed solutions were not guaranteed, as survival depended largely on political patronage in this hierarchical social context. Nevertheless, once actors co-learn the benefits of such solutions, they are unlikely to give up; instead, momentum tends to spiral outward.
