BillDesk
“BillDesk built India's original bill payment infrastructure back when paying your electricity bill online felt like science fiction — and somehow convinced every major bank, biller, and government department to route through their rails for two decades. The cruel irony is that the deeper those integrations run, the more they resemble critical infrastructure that nobody wants to touch, even as UPI and direct bank-to-biller APIs make the entire aggregation layer feel charmingly anachronistic.”
