The advancement of digital technologies and the consolidation of the platform economy have driven new models of logistics organization, with crowdsourcing standing out as an innovative alternative for the last mile. This model mobilizes underutilized resources from the population – such as vehicles and informal labor – through digital platforms that connect service providers to users. In large urban centers in Brazil, such as São Paulo and Rio de Janeiro, these solutions have changed traditional distribution paradigms. This article aims to evaluate the performance of the Loggi, Rappi, and 99Frete platforms, considering three dimensions: operational efficiency, economic viability, and social and regulatory impacts. The methodology is based on international studies and the concept of crowd logistics, identifies advances in flexibility and inclusion, and also points out challenges such as job insecurity, urban sustainability, and legal gaps. The study contributes to the debate on innovation, social justice, and digital transformation in Brazilian urban logistics.
