Retailers finally have a tool that doesn't require a bank
From within the corridors of Brazil's largest private bank, two executives have stepped out to build something smaller and, they hope, faster. Robbin, their new fintech venture, enters the installment payment space with a precise ambition: to give retailers a direct path to offering customers the ability to pay in installments, without the weight of traditional banking infrastructure. It is a story as old as commerce itself — the search for a more fluid exchange between buyer and seller — now being rewritten in the language of APIs and open banking.
- Brazilian retailers have long been caught between slow, expensive bank partnerships and the impossible task of building their own credit systems — Robbin is betting it can fill that gap before anyone else does.
- The founders carry rare institutional knowledge from Itaú, giving them credibility in a market where trust and operational precision can make or break a fintech before it finds its footing.
- Brazil's open banking framework, live since 2020, has unlocked payment rails once sealed inside legacy banks, creating a narrow but real window for startups to compete on infrastructure that was previously untouchable.
- The company now faces a two-front battle: nimble fintech rivals racing toward the same retailers, and the very banks their founders left, which are building digital payment solutions of their own.
- Whether Brazilian consumers will extend trust to a new name in installment finance — and whether Robbin can scale across a retail landscape as varied as São Paulo malls and interior family shops — remains the defining question ahead.
Two former Itaú executives have launched Robbin, a fintech startup with a focused mission: equip retailers to offer installment payment options directly at the point of sale. Their background at Brazil's largest private bank is not incidental — it shapes how they understand credit decisions, payment infrastructure, and the practical needs of merchants whose customers want to split purchases into monthly payments.
Retailers in Brazil have historically faced an uncomfortable choice: absorb the cost and rigidity of bank partnerships, or attempt to build credit infrastructure that lies far outside their expertise. Robbin positions itself in that gap, allowing a customer to choose a three-, six-, or twelve-month payment plan without ever leaving the checkout counter.
The model has proven itself elsewhere — Affirm and Klarna built major businesses on similar logic in the United States and Europe — but Brazil presents its own terrain. High interest rates, a large unbanked population, and a retail sector spanning major chains and small family businesses mean that local fluency matters as much as technical capability. The founders' years inside Itaú may be their most durable advantage.
Broader conditions are working in Robbin's favor. Brazil's open banking framework has made customer data and payment rails more accessible to startups, and regulatory shifts have lowered barriers for new financial services entrants. Still, competition is intensifying — from fellow startups and from the traditional banks themselves, including Itaú, which is watching closely. The coming months will test whether institutional knowledge, translated into a leaner operation, can move faster than the institutions that produced it.
Two former executives from Itaú, Brazil's largest private bank, have launched a fintech startup called Robbin with a straightforward mission: give retailers the tools to let their customers buy now and pay later. The company is entering a crowded but still-expanding corner of Brazilian finance—the installment payment space—where traditional banking infrastructure has left room for newer, faster solutions.
The founding team's background at Itaú matters. These are not first-time entrepreneurs learning fintech from YouTube tutorials. They understand how credit decisions get made, how payment systems talk to each other, and what retailers actually need when a customer wants to split a purchase into monthly chunks. That institutional knowledge is their competitive edge in a market where trust and operational reliability are not optional.
Retailers in Brazil have long faced a friction point: accepting installment payments requires either partnering with a bank (slow, expensive, inflexible) or building their own credit infrastructure (expensive, risky, and outside their core business). Robbin sits in that gap. The company's platform lets retailers offer installment options at the point of sale—meaning a customer can walk into a store, pick out goods, and immediately choose to pay in three, six, or twelve months without leaving the checkout counter.
This is not a new idea globally. Companies like Affirm and Klarna have built billion-dollar businesses on the same premise in the United States and Europe. But Brazil's retail landscape is different. The country has high interest rates, a large unbanked population, and retailers that range from small family operations to major chains. A solution that works for a São Paulo shopping mall may not work for a store in the interior. Robbin's founders presumably understand these local variations in ways that foreign competitors might not.
The timing reflects broader shifts in Brazilian fintech. The country's open banking framework, which went live in 2020, has made it easier for startups to access customer data and payment rails that were previously locked inside traditional banks. Regulatory changes have also lowered barriers to entry for new financial services companies. Robbin is one of dozens of startups trying to capture a piece of consumer finance that Itaú, Bradesco, and Santander have traditionally controlled.
For retailers, the appeal is clear: installment options can increase average transaction size and customer loyalty. A customer who might hesitate to spend 500 reais on a single purchase might feel comfortable spreading it across five months. For Robbin, the business model likely involves taking a small cut of each transaction or charging retailers a monthly subscription fee. The company makes money when retailers use the platform; retailers make money when customers buy more.
What remains to be seen is whether Robbin can execute at scale and whether Brazilian consumers will trust a new fintech with their installment payments. The company will also face competition not just from other startups but from the banks themselves, which are rapidly building their own digital payment solutions. Itaú, the very institution the founders left, is certainly watching. The next phase will reveal whether two former bankers can move faster and more nimbly than the institutions they once worked for.
A Conversa do Hearth Outra perspectiva sobre a história
Why would two people leave Itaú to start this? They had security, status, salary.
Because they saw something the bank was slow to do. Installment payments at retail are still clunky in Brazil. Banks make money on credit cards and loans, not on making the checkout experience frictionless for a store owner.
So this is about speed—moving faster than a big bank can?
Partly that. But also focus. Itaú does everything. Robbin does one thing well. A retailer doesn't have to navigate a bank's bureaucracy; they just integrate an API.
Who actually takes the credit risk here? If a customer doesn't pay their installments, who loses money?
That's the crucial question. Robbin probably either absorbs some risk themselves, partners with a bank to underwrite, or uses some kind of insurance. The source doesn't say, but it's the difference between a sustainable business and a house of cards.
And the customer—what's in it for them versus just using a credit card?
Maybe better terms, maybe faster approval, maybe the ability to pay in installments without a credit card at all. In Brazil, that last part matters. Not everyone has a card with available credit.
So this is really about financial inclusion, not just convenience?
It could be. If Robbin can let a person with limited credit history buy something and pay over time, that's different from what the banks offer. But we don't know their underwriting standards yet.
