Digital Public Infrastructure (DPI) in India such as Aadhaar, eKYC, and UPI have transformed governance and fueled the growth of the startup ecosystem. Aadhaar enabled efficient delivery of government services and benefits, saving an estimated $34 billion. UPI became the dominant digital payment method in India, driving financial inclusion. DPIs have also impacted private businesses by streamlining operations and enhancing customer experiences. Emerging DPIs like ONDC aim to further democratize commerce across sectors. The synergistic relationship between DPIs and the startup ecosystem is poised to propel India's digital transformation and economic growth.
