Brazil is the only market where four structurally distinct digital banking models are all profitable at scale, at the same time.
- Nubank bet on the credit card. Starting with a single no-fee purple card, it turned underwriting the underbanked into the world’s largest digital bank, now compounding on proprietary AI and a credit-first engine that monetises customers before it ever sells them a second product.
- Inter bet on the super app. Rather than one hero product, it stacked seven verticals, from banking to e-commerce to insurance to investments, onto a single self-funded balance sheet, wagering that owning the whole customer relationship beats owning one transaction.
- C6 bet on collateral. It built a disciplined, low-risk credit machine running at 45% ROE, with JPMorgan as a strategic partner, proving that secured lending, not viral growth, can be the fastest route to elite returns.
- Magalu bet on the store. Instead of building a bank customers come to, it embedded finance inside a retail ecosystem that already touches millions of shoppers daily, turning payments and credit into a natural extension of the checkout.
In four weeks, live agent payments landed in the Netherlands, Ukraine, France, and Mexico. India got its first agentic protocol on UPI. Starling put a scam-checking agent in front of five million customers, and BBVA counted 100,000 employees on ChatGPT Enterprise. Then Washington changed the rules entirely, an export order pulled Anthropic’s newest models from the market mid-month, and regulators set the terms of their return while OpenAI slowed a launch of its own.
And behind all of it, the money moved: Anthropic and OpenAI filed confidential S-1s a week apart, at valuations last reported near $965 billion and $852 billion.
For years, SME banking in the UK moved slower than the businesses it served.
Accounts took time to open, fees were hard to decode, and financial admin sat across disconnected tools. For sole traders and SMBs, banking often added friction instead of removing it.
And while Monzo did not begin as an SME bank, its business banking rise came after it had built a consumer brand around speed, simplicity, and mobile-first money management. When Monzo brought that playbook to SMEs, it entered a market ready for a cleaner alternative. By 2026, it was serving 905K businesses, roughly 1 in 7 UK businesses.
Is Starling the digital bank that won by behaving like a traditional bank?
Starling is NOT the UK’s biggest neobank, but it may be one of its most disciplined. From building a full-stack bank before chasing scale, to using deposits, secured lending, cost control, and Engine by Starling to create a sustainable operating model, Starling offers a different challenger-bank playbook: bank first, app second.
Stripe’s agentic commerce strategy begins with a shift in what software can do. AI assistants are moving beyond writing, searching, and coding. They are beginning to shop, book, pay, invest, and borrow on behalf of users. Once agents begin transacting with real money, every part of finance needs the same foundation. A trusted way for agents to pay.
That foundation is where Stripe is making its move.
As Visa, Mastercard, Google, Coinbase, OpenAI, Tempo, and others race to define how agent payments should work, Stripe is taking a different route. It has co-authored payment standards, opened them for others to use, and built support for rival protocols through a single integration. The visible standards remain open. The value collects beneath them.
Klarna’s AI story began under pressure.
By 2022, the company was operating in a very different market environment. Its valuation had fallen from the highs of the fintech boom, losses were drawing closer attention, and investors were placing greater emphasis on efficiency alongside growth.Â
What followed was one of the most aggressive AI transformations in fintech services.
Klarna pushed AI into the core mechanics of the company: customer service, shopping discovery, advertising, credit underwriting, software development, marketing, data analysis, and workforce design. By 2025, it had become a leaner, more technical organization, with revenue more than doubling from Q4 2022 while operating expenses declined.
Adyen is one of those companies that still gets described as a payments processor, even though the business has moved far beyond that label. What began as a single-platform payments stack in 2006 has evolved into a global fintech infrastructure layer spanning acquiring, unified commerce, embedded finance, AI, and platform-led distribution.
Adyen avoided the usual payments trap: growing by stitching together local providers, point solutions, and market-specific integrations. Its bet was architectural discipline. Build the stack in-house, keep one global integration, and let every new layer compound on the same core. A single-platform foundation in 2006. Global scaling from 2012. Unified Commerce from 2017. Embedded finance and AI from 2022 onward. Each phase expanded the surface area, but preserved the same underlying logic.
In May 2026, agentic finance moved from isolated proofs into distribution infrastructure. Mastercard took Agent Pay live across Portugal and the Netherlands. Visa expanded Agentic Ready across Asia Pacific and CEMEA, enrolling issuers before agent volume arrives. Stripe, Coinbase, Circle, Fireblocks, MoonPay, and AWS turned crypto and stablecoin rails into usable infrastructure for agent-initiated payments.Â
Banks stopped treating agents as experiments. Fiserv and FIS packaged agent capabilities for bank clients. Lloyds and Citi built internal agent platforms with marketplaces, monitoring, and audit. Robinhood opened brokerage and card rails to customer-controlled AI agents. OpenAI connected ChatGPT to more than 12K+ financial institutions, while Anthropic turned finance agents into off-the-shelf products.
Singapore is often painted as the crown jewel of Asian fintech, highly digital, affluent, and open to innovation. But it is also crowded and highly competitive. While well-funded local consortia built full-scale digital banks and absorbed heavy losses, Revolut took a leaner path. Operating without a full banking licence, the UK challenger grew its Singapore retail customer base by 40% and reached a 15% net profit margin in 2024.Â
That raises a compelling strategic question: how did Revolut capture the highly lucrative Singapore market while capital-heavy digital banks stalled in the red?
From simplifying online payments for developers to processing $1.9T in annual payment volume, Stripe has evolved into one of the most important financial infrastructure companies powering the internet economy. Stripe’s next act is expanding the scope of payments infrastructure, powering AI-native businesses, agent-led commerce, and programmable money movement across the next generation of digital transactions.
At WhiteSight, we’ve unpacked the strategy behind Stripe’s expansion, decoding how its product stack, AI investments, platform ecosystem, and stablecoin bets are reshaping the future of payments, commerce, and financial infrastructure.
In a market where many fintechs are still fighting to prove single-product economics, SoFi has taken a different route: turning a student-loan refinancing wedge into a full-stack financial platform with banking, lending, investing, and B2B infrastructure under one roof.
What began as a niche play for high-earning graduates has evolved into a nationally chartered bank, a multi-product consumer finance ecosystem, and an infrastructure business powered by Galileo and Technisys. With 13.7M members, 20M+ products, and a growing fee-based revenue engine, SoFi is trying to become the operating system behind modern financial services.
Affirm’s evolution from a point-of-sale financing provider into a broader consumer payments platform reflects how the Buy Now, Pay Later (BNPL) model has matured. As the industry questioned whether BNPL could remain resilient through changing economic conditions, expand beyond the checkout button, and achieve sustainable profitability, Affirm successfully navigated all three challenges by transforming its transactional credit engine into a broader consumer financial ecosystem.
Rather than relying solely on the short-term, interest-free model that defined early BNPL, Affirm built a balanced approach combining interest-bearing loans for larger purchases with merchant-subsidized promotions that help retailers boost sales. By 2025, this strategy had driven significant scale, with net revenue reaching $3.2B and the company reporting $52M in positive net income.
