Learning to Innovate: WhatsApp Groups as Grassroots Innovation Ecosystems Among Micro-Entrepreneurs in Emerging Markets

Scholarly and policy analyses of innovation have traditionally privileged formal, capital-based research and development systems, thereby marginalising the dynamic, grassroots innovations in the informal digital spaces of emerging markets. This theoretical paper aims to critically interrogate this prevailing paradigm by redefining the WhatsApp groups of micro-entrepreneurs as decentralised, real-time innovation systems. Based on network theory and the Communities of Innovation (CoI) framework, we argue for the recognition of these groups as informal research and development laboratories. The platform's intrinsic architectural aspects, including instant multimedia sharing and real-time dialogue, facilitate rapid cycles of peer-to-peer problem solving, iterative prototyping, and shared learning. This process yields new forms of innovation, from incremental product variations to adaptive marketing techniques to robust crisis management strategies, all based on social capital and trust rather than formal institutional support. While the review recognises the significance of this emerging phenomenon, it also critically examines its inherent limitations, including the risks of echo chambers, the dissemination of misinformation, and the notable absence of intellectual property protections. By incorporating new empirical evidence from South Asia, we demonstrate how these digital networks serve as both spaces of significant creativity and sites of vulnerability. Through a theoretical analysis of these groups, this paper formulates a new theory of entrepreneurial resilience and outlines a future research agenda. It holds important implications for innovation theory, development policy, and digital platform design, calling for a shift in emphasis towards the identification and cultivation of the organic dynamics of grassroots innovators operating at the core of the informal economy.
