Nubank — What I Think
Nubank’s whole vision fits in one line: the customer’s enemy was the bank, so they made the customer’s anger the product.
Brazilian banking was a cartel. A handful of incumbents, grotesque fees, branch queues that ate your afternoon, and a credit card you had to practically beg for and then got abused by. Most fintech founders look at a market like that and think “better app.” David Vélez looked at it and thought “the hatred is the moat.” If incumbents are genuinely loathed, you don’t need a clever feature. You remove the things people hate, charge nothing for the basics, and let them tell their friends. Nubank’s growth engine was word-of-mouth powered by resentment of the alternative. That’s a far deeper insight than any UX detail. Build where the incumbent is hated, and your marketing budget is the customer’s grudge.
The first product tells you the strategy: a no-fee credit card, fully managed from a phone, purple and friendly in a market of cold marble lobbies. They led with the painful, profitable product, credit, not a wallet, not transfers. That’s contrarian and right. A wallet is a feature. A credit relationship is a P&L. They anchored on the hard thing, the thing banks made miserable, and made it humane. Then everything else, account, savings, investments, insurance, hung off a customer who already loved them.
What they got right is that financial inclusion and profitability aren’t opposed in an underbanked market. They’re the same trade. Tens of millions of Brazilians, Mexicans, Colombians had no card or a predatory one. Serving them first, with restraint, built the largest customer base in the region AND a real lending book, because the unbanked aren’t poor risks by nature, they’re just unmeasured. Nubank measured them with its own data and underwrote what the incumbents wouldn’t touch.
Where the vision gets tested: a low-cost, beloved brand still has to make the unit economics of credit work across a full cycle, in economies that go through inflation and default storms. Being loved is cheap acquisition. Being a bank is expensive risk. And Pix, Brazil’s free instant rails, commoditizes transfers, which actually helps Nubank, since they never depended on transfer float and Pix just deepens engagement. The real question is whether “nicer bank for the masses” stays a moat once every incumbent copies the app. The answer is the data and the love, if they hold both.
Favorite & worst CEO
- On its leadership: David Vélez, founder-CEO. I connect strongly with the core thesis, find a market where the incumbent is genuinely despised and let that resentment be your growth engine, then lead with the hard profitable product (credit) instead of the easy one (a wallet). It’s disciplined and contrarian and it scaled to one of the largest customer bases in fintech. The standing test of his vision is durability: nice + cheap is easy to admire and easy to copy, so the moat has to be the underwriting data and the brand love compounding faster than incumbents can imitate. Outstanding founding insight, and the long game is defending a moat made partly of feeling.
