Trust & the Local BrandThin moat

StoneCo (STNE) — moat facet

Being known as the small merchant's champion — a reputation the incumbents can't buy back.

Brands matter more to a small merchant than outsiders often assume. The shopkeeper is handing a company his daily takings and trusting it to move his money and back his credit; that trust is not extended to a faceless processor lightly. Stone built its name as the challenger that actually cared about the small business — the one that showed up, served fast, and treated the corner shop as a customer worth having rather than a rounding error — and that reputation is an asset in its own right.

Volume grew 28% in two years on the trust built merchant by merchant.

In a market where many merchants have been let down by big, indifferent banks, being known as the responsive, merchant-friendly option is a real advantage at the point of sale. Word travels in local business communities; a hub's reputation in its town is built one satisfied merchant at a time and spreads by referral, which is both cheap customer acquisition and a barrier, because a newcomer starts with no such standing.

But brand trust is the thinnest of Stone's advantages and the easiest to damage. It was dented by the 2021 credit misadventure, which reminded everyone that Stone could stumble; it is tested whenever service slips or a competitor undercuts on price; and it commands no premium a merchant won't abandon if the value proposition erodes. Trust is earned slowly and lost quickly. It genuinely helps Stone hold and win small merchants, but it is a supporting player in the moat, not the foundation — useful reinforcement for the harder advantages of distribution and integration, not a substitute for them — the rivals carry Itaú's and Santander's names, after all1.

Moat trajectory: Holding steady

Holding steady. Stone's name as the merchant-friendly challenger still helps it win and keep small businesses, and word-of-mouth in local communities keeps acquisition cheap. But brand trust is the thinnest of Stone's advantages: it was dented by the 2021 credit stumble, it commands no premium a merchant won't abandon if value erodes, and it is tested every time service slips or a rival undercuts on price. It holds real value as reinforcement for the harder advantages of distribution and integration, but it is neither growing nor collapsing — a supporting player keeping its footing.

The number that tests this moat
Third-party estimate
StoneCo payment volume growth against Brazilian card volume
+8.7% against +10.1% (2025)

Stone's brand works because the incumbent acquirers belong to banks merchants distrust. Growing more slowly than the card market means share is being lost anyway, and the bank-owned Rede gained about five points in the year.
