Episode notes
Modular Building Blocks Enable Scale
- India Stack was designed as loosely coupled building blocks to enable combinatorial innovation at scale.
- That modular design allowed independent evolution of Aadhaar, eSign, DigiLocker and UPI and eased broad adoption.
UPI Born From A Street Vendor Problem
- UPI's origin was tied to solving micro-loans for a street vendor and envisioned payments as a mostly-free public utility.
- Early adopters varied: some startups ignored it, Razorpay slowed due to Mastercard pressure, while PhonePe and others later scaled it.
Capture Growth By Embracing Lower Prices
- Entrepreneurs must pivot from protective pricing to capturing larger markets by lowering costs.
- Perfios adopted cheaper consent-driven data access and grew into a major player instead of resisting disruption.
