Nubank

Nubank makes money from credit card interchange fees (1-3% of every transaction), interest on credit card balances and personal loans, and net interest income from deposits (lending out customer deposits at higher rates than it pays in savings interest). The company also earns fees from insurance products and investment marketplace commissions.

The key insight is that by being digital-only with no branches, Nubank's cost to serve a customer is roughly 85% lower than traditional Brazilian banks.

Sea Group

Sea runs three distinct businesses under one roof, and the genius of the structure is how they feed each other.

Garena is the gaming division. It develops and publishes games — most famously Free Fire, which Sea built itself after years of just licensing other people's games.

Free Fire launched in 2017 and became a phenomenon in emerging markets. It's a battle royale game optimized for low-end Android devices and slow internet connections.

Exactly the phone most people in Southeast Asia, Latin America, and India actually own. Garena makes money through in-game purchases — skins, characters, seasonal passes.

At its peak, Free Fire had over 100 million daily active users.

Shopee is the e-commerce marketplace. It operates like a hybrid of Amazon and eBay — sellers list products, buyers purchase, Sea handles payments, logistics coordination, and marketing.

Shopee makes money through advertising, transaction fees, and value-added services for sellers. It's now the dominant e-commerce platform in Southeast Asia and has a significant presence in Brazil.

SeaMoney is the fintech arm. It offers mobile wallets, digital payments, buy-now-pay-later, and banking services through MariBank in Singapore.

The pitch is simple: hundreds of millions of people in Southeast Asia are unbanked or underbanked. Give them a mobile wallet tied to their Shopee account and they'll use it for everything.

It's the super-app play, executed patiently.

David Vélez grew up in Colombia, studied at Stanford Business School, and worked at Sequoia Capital in Silicon Valley. In 2012, Sequoia sent him to Brazil to find investment opportunities.

What he found instead was the worst banking experience he'd ever encountered.

Brazilian banks were controlled by five massive institutions that charged outrageous fees — annual credit card fees of $200+, account maintenance fees, fees on fees. Customer service was a nightmare.

Branches required hours of waiting. The banks had zero incentive to improve because they had a captive market of 200 million people and no competition.

Vélez saw the opportunity and left Sequoia to start Nubank in 2013 with Cristina Junqueira (a former Itaú banker) and Edward Wible (a Princeton engineer). Their first product was a purple credit card — no annual fee, managed entirely through a beautiful app, with transparent billing and real-time notifications.

In a country where banks treated customers like an inconvenience, Nubank treated them like human beings.

Sea Group

Forrest Li moved from China to Singapore in 2005 to do his MBA at Stanford. He didn't go back.

In 2009, he founded Garena — which literally means 'Global Arena' — as an online gaming platform for Southeast Asia. The region was massively underserved.

Hundreds of millions of young, mobile-first users with low PC penetration but exploding smartphone adoption. Nobody was building for them.

Li saw that gap and went straight at it.

Garena started by licensing popular PC games — League of Legends, FIFA Online — and localizing them for markets like Indonesia, Thailand, Vietnam, and the Philippines. It was a straightforward licensing model, unglamorous, not the kind of thing that gets TechCrunch headlines.

But it worked. Garena quietly became the dominant gaming platform across Southeast Asia.

The company rebranded to Sea Limited in 2017 when it IPO'd on the New York Stock Exchange, raising $884 million. By then, Li had already launched Shopee in 2015 — an e-commerce marketplace — and SeaMoney, a digital payments and financial services arm, was taking shape.

Three businesses. One holding company.

The bet was that gaming would fund the others until they could stand on their own. That's exactly what happened.

Nubank

Nubank grew through word of mouth in a country where everyone hated their bank. The product was so much better than the alternative that customers became evangelists.

The invite-only launch created exclusivity and a waitlist that hit millions. People would beg friends for an invite code because getting a Nubank card felt like escaping prison.

The cost advantage was structural. Traditional Brazilian banks operated thousands of branches with tens of thousands of employees.

Nubank had an app and a customer service team. This let Nubank offer free products that banks charged hundreds of dollars for.

The unit economics were unbeatable — when your competitor has 4,000 branches and you have zero, you can afford to be generous.

Geographic expansion into Mexico and Colombia replicated the playbook. Both countries had the same banking problem — concentrated, fee-heavy, customer-hostile banks.

Nubank launched in Mexico in 2019 and Colombia in 2020. Mexico alone already has over 8 million Nubank customers.

Sea Group

The counterintuitive move was using gaming to subsidize e-commerce. Most tech companies pick a lane.

Sea used Garena's cash flows — which were enormous when Free Fire was at its peak — to fund Shopee's aggressive, money-losing expansion. They didn't need to raise debt or dilute shareholders to burn cash in new markets.

The gaming division was basically an ATM.

Free Fire itself was a masterclass in product-market fit. Instead of porting a premium game to low-end markets and watching it fail, Sea built a battle royale game from scratch that ran on 1GB RAM Android phones with patchy 3G connections.

The game was optimized for exactly the hardware that 800 million people in emerging markets actually owned. Nobody else was doing that.

Shopee's growth hack was localization taken to an almost absurd degree. They didn't just translate the app.

They hired local teams in every market, ran country-specific campaigns, integrated local payment methods, and partnered with local logistics providers. In Brazil, they ran Shopee-branded motorbike delivery.

In Indonesia, they integrated with hundreds of local courier companies. The playbook was: be more local than the locals.

The final piece was the flywheel. A Garena user downloads Free Fire, spends money on in-game items using SeaMoney's wallet, then starts buying physical goods on Shopee with the same wallet.

Three products, one ecosystem, one user. That's the compounding effect Li was building toward from day one.

Nubank

The IPO timing was terrible. Nubank went public on the NYSE in December 2021 at a $41 billion valuation.

The stock immediately crashed as the global tech sell-off hit and rising interest rates in Brazil increased the cost of capital. The stock fell from $12 to under $4 by mid-2022.

Vélez had to spend a year convincing investors that a Brazilian digital bank was worth owning during a global risk-off environment.

Credit risk in Latin America is inherently higher. Brazil has volatile inflation, currency risk, and a large unbanked population with limited credit history.

Nubank's loan book grew rapidly, and delinquency rates spiked in 2022 as Brazil's economy slowed. Managing credit risk at scale in emerging markets is fundamentally harder than in developed economies.

Nubank has since tightened underwriting and delinquency has improved, but it remains the biggest operational risk.

Regulatory complexity across three countries is a constant headache. Brazil, Mexico, and Colombia each have different banking regulations, consumer protection laws, and compliance requirements.

Navigating three regulatory environments simultaneously while growing at speed requires significant legal and compliance investment.

Sea Group

The post-pandemic collapse was brutal and nearly existential for the stock, if not the business. During COVID, Sea was the perfect story — gaming was up, e-commerce was up, digital payments were up.

The stock hit $372 in October 2021. Market cap touched $200 billion.

Sea was the most valuable company ever to come out of Southeast Asia.

Then the world opened back up. Free Fire's daily active users fell off a cliff as people left their homes again.

Garena had funded the empire, and now the empire's funding engine was broken. Sea lost its license to publish Free Fire in India after the Indian government banned Chinese-linked apps.

India had been a massive market. Gone overnight.

Sea responded by cutting costs aggressively — laying off staff, retreating from markets like France, Spain, Poland, and India where Shopee had expanded without yet reaching profitability. The stock fell from $372 to under $40 by early 2023.

A 90% drawdown. That's not a correction.

That's a reset.

The deeper challenge is structural. Shopee competes with Lazada (backed by Alibaba), TikTok Shop (which has exploded in Southeast Asia), and increasingly with Temu and Shein.

These are not small competitors. TikTok Shop in particular has disrupted the e-commerce landscape in Indonesia and Thailand faster than most analysts expected.

Sea has scale and local knowledge, but the fight for Southeast Asia's e-commerce market is far from over.

Nubank

Nu Credit Card is the flagship — a no-annual-fee Mastercard managed entirely through the app. NuConta is the digital bank account with free transfers and bill payments.

Nu Invest is the investment platform offering stocks, ETFs, and fixed income. Personal Loans are offered based on credit behavior within the app.

Nu Life Insurance and other insurance products are distributed through the app. Ultraviolet is the premium tier with higher limits, airport lounges, and additional perks.

NuPay is the payments solution for merchants.

Sea Group

Free Fire is the crown jewel — a mobile battle royale game with over 100 million daily active users at its peak, built specifically for low-end Android devices in emerging markets. It's been the most downloaded mobile game globally multiple times and remains dominant across Southeast Asia and Latin America despite declining from its COVID peak.

Shopee is Sea's e-commerce marketplace and the business with the highest long-term ceiling. It operates across Singapore, Malaysia, Indonesia, Thailand, Vietnam, Philippines, Taiwan, and Brazil.

It's consistently ranked the most-visited e-commerce site in Southeast Asia. The app includes livestream shopping, local seller tools, Shopee Pay, and Shopee Food in select markets.

SeaMoney — now operating as the financial services umbrella — includes ShopeePay (mobile wallet integrated with the Shopee checkout), SeaBank (a licensed digital bank in the Philippines and Indonesia), and MariBank (a digital bank in Singapore). The pitch is financial inclusion for the underbanked, backed by transaction data from Shopee.

Sea Group

Sea went public in 2017 without needing a late-stage mega-round from the usual suspects. But it had institutional backing from early on.

Tencent is the most significant external shareholder — the Chinese gaming giant held a roughly 22% stake at various points, which gave Sea both credibility in gaming and a complicated geopolitical headache as anti-China sentiment grew in Southeast Asia and the U.S.

Naveen Tewari's General Atlantic and other growth equity funds participated in rounds before the IPO. Post-IPO, Sea attracted attention from large institutional investors including T.

Rowe Price, BlackRock, and various sovereign wealth funds drawn to the Southeast Asia growth story.

Masayoshi Son's SoftBank also took a stake — consistent with SoftBank's bet on emerging market consumer internet platforms. The Tencent relationship is the most interesting one because it's both a competitive asset (access to gaming IP and distribution) and a liability (political risk in markets sensitive to Chinese corporate influence).
