Flipkart

Marketplace model — Flipkart connects third-party sellers with consumers and takes a commission on every transaction, typically 5% to 25% depending on the category. Also operates a first-party retail business buying and reselling products directly, particularly in electronics and fashion.

Revenue streams include seller commissions, advertising (brands pay to appear in search results and banners), logistics services (Flipkart's in-house delivery network, Ekart, also serves other companies), and Flipkart Plus (loyalty program). The company runs periodic mega-sales — Big Billion Days — that generate billions in GMV over a few days, essentially India's version of Prime Day.

Stripe

Stripe charges a flat 2.9% + $0.30 per transaction. That's it.

No setup fees, no monthly fees, no hidden charges. The simplicity is the product.

When a customer pays on a website using Stripe, Stripe handles everything — fraud detection, currency conversion, bank transfers, tax calculation, compliance. The merchant just sees money arrive in their account.

On top of the core payments, Stripe has built an entire financial infrastructure stack. Billing for subscriptions, Connect for marketplace payments, Atlas for incorporating a company, Issuing for creating virtual cards, Treasury for banking-as-a-service, and Radar for fraud prevention.

They're basically building the financial plumbing for the entire internet.

Sachin Bansal and Binny Bansal — not related despite the shared surname — both worked at Amazon in its early days. They moved back to India in 2007 and started Flipkart as an online bookstore, literally copying the Amazon playbook from 1994.

Their first order was a book called "Leaving Microsoft to Change the World," which is almost too on-the-nose. But India in 2007 was nothing like America in 1994.

Internet penetration was low, credit cards were rare, delivery infrastructure was nonexistent, and most people had never bought anything online. The Bansals had to invent solutions for problems Amazon never faced.

Cash-on-delivery became the default payment method. They built their own logistics network because India Post couldn't handle e-commerce volumes.

Every assumption that worked in the US had to be rebuilt from scratch for India.

Patrick Collison was 19. His brother John was 17.

They had already built and sold a company — Auctomatic, an eBay auction tool — for $5 million while still teenagers in Limerick, Ireland. Patrick went to MIT, John went to Harvard, and they both dropped out because they had a better idea.

The idea was embarrassingly obvious in hindsight. In 2010, accepting payments on the internet was a nightmare.

You had to get a merchant account, negotiate with a payment processor, deal with a gateway provider, handle PCI compliance, and write thousands of lines of code. It took weeks or months.

The Collisons thought it should take five minutes.

They built a simple API — seven lines of code — that let any developer start accepting credit card payments immediately. No merchant account.

No paperwork. No phone calls with banks.

Just paste seven lines of code and you're in business. They originally called it /dev/payments, then changed it to Stripe in 2011.

Peter Thiel and Elon Musk — the PayPal mafia — were among the first investors. Sequoia and Andreessen Horowitz piled in soon after.

The Collisons had built exactly what every developer on Earth had been wishing for.

Flipkart

Category expansion from books to electronics to fashion to groceries — each new category brought new customers and increased purchase frequency. Cash-on-delivery removed the trust barrier for first-time online shoppers.

Building Ekart logistics gave Flipkart delivery reach into tier-2 and tier-3 cities that no third-party carrier could serve. Big Billion Days mega-sale events trained Indian consumers to shop online with massive discounts.

Acquisition strategy — bought Myntra (fashion), Jabong (fashion), eBay India (marketplace), and PhonePe (payments) to consolidate the market. Walmart's $16 billion acquisition in 2018 provided unlimited capital to compete with Amazon India.

Mobile-first design because most Indian consumers access the internet through smartphones, not computers.

Stripe

Stripe grew almost entirely through developer love. They didn't hire a sales team for years.

They didn't run ads. They just built the best developer documentation anyone had ever seen and let word of mouth do the rest.

The developer-first strategy was deliberate. The Collisons realized that in a startup, the developer usually decides which payment provider to use.

If you make the developer happy, you win the company. Stripe's API documentation became legendary — clear, beautiful, with working code examples in every language.

They also grew by growing with their customers. Early Stripe customers included tiny startups that later became giants — Lyft, DoorDash, Instacart, Shopify.

As those companies scaled to billions in revenue, Stripe's processing volume scaled with them. Stripe didn't need to acquire new customers because its existing ones kept getting bigger.

The international expansion was methodical. Instead of launching everywhere at once like Uber, Stripe carefully added country after country, making sure each one worked perfectly with local payment methods, currencies, and regulations.

By 2024 they were processing payments in 195 countries.

Amazon India is a relentless competitor with Jeff Bezos publicly committing billions to win the market. Regulatory uncertainty — Indian e-commerce regulations around foreign ownership, deep discounting, and marketplace rules change frequently and can disrupt business models overnight.

Profitability has remained elusive despite massive scale — the combination of deep discounts, logistics costs, and competitive spending keeps margins thin. The Walmart acquisition created enormous pressure to demonstrate returns on a $16 billion investment.

Founder drama — Sachin Bansal was forced out after the Walmart deal over allegations of personal misconduct, creating leadership turbulence. And the fundamental challenge of e-commerce in India: a price-sensitive market where consumers will switch platforms for a 50-rupee discount.

Stripe

Valuation whiplash. In 2021, Stripe hit a peak valuation of $95 billion during the fintech boom.

By 2023, they had to mark it down to $50 billion during the tech correction — a 47% drop that made headlines everywhere. Employees who had been paper millionaires suddenly weren't.

The valuation has since recovered to $91 billion after a secondary share sale in 2025, but those two years were rough for morale.

Competition is relentless. Adyen, the Dutch payments company, has been eating into Stripe's enterprise market.

Square (now Block) competes on the small business side. PayPal is everywhere.

New fintech players pop up constantly. The payments business has razor-thin margins and everyone is fighting for the same 2.9%.

Going public is the elephant in the room. Stripe has been expected to IPO for years.

Investors, employees, and the media keep asking when. The Collisons have consistently said they're in no rush, but with $8.7 billion raised and thousands of employees holding stock options, the pressure to provide liquidity is enormous.

As of 2025, they've opted for secondary sales instead of a public offering.

Stripe

Stripe Payments is the core — accept credit cards, debit cards, Apple Pay, Google Pay, and 135+ payment methods in 195 countries. Stripe Connect lets marketplaces and platforms pay out to sellers (Shopify, Lyft, DoorDash all use it).

Flipkart
