“Paytm built India's digital payments revolution from scratch — 300 million users, 44 million merchants, and the rare achievement of turning 'Paytm karo' into a verb that survived even UPI's arrival. The exquisite irony is that their greatest success — making digital payments so ubiquitous that every chai wallah has a QR code — created the very infrastructure that now makes Paytm itself optional.”
