PhonePe — What I Think

Prajjwal Chittori · August 2023

PhonePe won by refusing to own the thing everyone else was fighting over.

While Paytm defended its wallet, its float, its lock-in, its little walled balance, PhonePe made the opposite bet. It built natively on UPI from day one and treated the wallet as dead on arrival. The thesis was almost zen. Don’t try to hold the user’s money. Just be the cleanest pipe between their bank and everyone else’s. In a country that had just made interbank transfer a free public utility, deciding NOT to own the money was the entire winning move. Most founders can’t do that. Holding the balance feels like holding the customer. PhonePe understood that on open rails, the balance is a liability and the experience is the asset.

I find this beautiful as an engineer. UPI is infrastructure. Boring, neutral, government-blessed plumbing. The companies that won on top of it accepted they were building an interface to a commodity and competed on speed, reliability, and the next layer up. PhonePe obsessed over the thing users actually feel: does the payment go through, instantly, every time, on a cheap phone with bad signal in a tier-three town. That reliability obsession at India’s scale is genuinely hard backend work, and it’s the real moat. Not the float.

Second smart move: use payments as a zero-margin customer acquisition machine, then climb the value chain. Payments don’t make money in India, the regulator killed the merchant fee on the most common transactions. So PhonePe treated transactions as a loss-leader habit and built insurance, mutual funds, gold, and a merchant lending surface on top of a base of users who open the app daily out of reflex. Get the habit free, monetize the trust later. That’s the only viable shape of an Indian fintech, and they saw it cleanly.

Where I’d push back: distribution-led growth has a ceiling that looks like a moat until it doesn’t. A lot of PhonePe’s reach came from being bundled and pushed hard, and UPI’s deliberate market-share caps loom over anyone who gets too dominant. The open network that handed them the win can just as easily flatten them. On public rails, nobody gets to be a monopoly for long. That’s the point of public rails.
