This chapter examines the interrelationship between microenterprises and networks in the performance of Jua Kali small, medium, and micro enterprises in Nairobi City County, Kenya. The chapter integrates qualitative insights from interviews and focus groups with quantitative survey data from artisans across various sub-counties through a mixed-methods approach. Qualitative findings reveal that artisans form networks out of necessity, driven by unemployment and family pressures, creating trust-based, informal ties that provide resources but risk stagnation. Quantitative analysis shows that larger networks may hinder performance due to coordination challenges, while diverse networks enhance resource sharing and resilience. Strong, cohesive networks foster trust and collaboration, supporting business survival, though inconsistent communication can limit effectiveness. Structured networks with clear roles and accountability improve resource flow and performance of the microenterprises in the informal economy. Gender and location influence network formation, with women leveraging supportive groups and men tapping trade-specific ties. The study underscores the dual role of social networks as both enablers and constraints in the informal economy. The chapter discusses the findings about the performance-network connection among Jua Kali artisans in a broader context.
