Agricultural entrepreneurs are turning to a range of technological tools—from artificial intelligence (AI), the Internet of Things (IoT), remote sensing and blockchain, big data analytics, mobile apps, and GIS mapping—to fill significant gaps in the agricultural value chain. These enterprises are transforming agricultural services using digital payment systems, precision farming, real-time weather forecasting, and farm-to-fork logistics by adopting a user-centric, scalable, and affordable model. Sustainable Development Goals are viewed in this paper as the agrarian start-ups the sustainability of which includes the attainment of zero hunger (SDG 2), decent work and economic growth (SDG 8), industrial and innovation (SDG 9), and climate action (SDG 13). The ecosystem, however, faces several difficulties. Problems include insufficient last-mile digital infrastructure, low digital literacy among farmers, restricted access to early-stage investment, regulatory restrictions, and scalability limits continue to hinder the widespread adoption and efficacy of agritech solutions. This article carefully examines these issues and offers institutional, regulatory, and investment-level remedies to help agri-entrepreneurship flourish. This paper claims that agri-startups are critical for India's agricultural modernization and rural revival. By promoting innovation at the local level and providing data-driven, scalable solutions, these businesses are generating commercial value while also enhancing environmental resilience, income, and food security. As India works to be a world leader in sustainable agriculture, understanding and supporting the agri-startup ecosystem becomes increasingly crucial.
