How Stripe Built the Payment Infrastructure for the Internet Economy

Lucas: Luna, I want to talk about a company that built one of the most quietly powerful business models of the last decade, and it all started with a seven-line integration. Luna: Stripe. I’m guessing. You don’t get much more developer-first than that.

Lucas: Exactly. Stripe launched in 2011 with a tagline that was basically, ‘payments for developers.’ Before Stripe, accepting payments online meant dealing with merchant accounts, payment gateways, PCI compliance - a huge headache. Stripe made it a few lines of code.

Luna: And what looked like a product decision was really a business model decision. By targeting developers, they built a distribution channel that scaled without a sales team. Lucas: Right. Stripe’s early growth came from developer word of mouth.

A developer at one startup would use Stripe, then move to another company and bring Stripe with them. That’s incredibly sticky. Luna: But let’s talk about the actual business model. Stripe makes money primarily through transaction fees, right?

Typically 2.9 percent plus thirty cents per transaction in the US. Lucas: Yes, that’s the headline. But the real genius is in the two-sided network they built.

On one side, they have millions of businesses processing payments. On the other, they have platforms like Shopify, Lyft, and DoorDash that use Stripe to power their own marketplaces. Luna: So Stripe Connect. That’s the product that lets platforms handle payouts to their sellers or drivers.

That’s a different revenue stream, right? Lucas: Exactly. Connect charges a platform fee plus a percentage of each payout. It’s not just processing; it’s facilitating an entire flow of money.

And because Stripe sits in the middle, they have data on both sides, which creates a moat. Luna: I’ve read that Stripe’s payment volume has grown from about $10 billion in 2014 to over $1 trillion in 2025. That’s a compound annual growth rate of roughly 40 percent. Lucas: Yeah, that’s the core metric - payment volume.

And they’ve expanded beyond simple payments too. Stripe Atlas lets you incorporate a company in Delaware from anywhere. Stripe Issuing lets businesses create their own credit cards. They’re effectively becoming the financial operating system for internet businesses.

Luna: It’s reminiscent of what Amazon did with AWS. Start with a painful internal need, build a product for yourself, then realize others have the same pain. Stripe’s founders, the Collison brothers, were early employees at Auctomatic, so they knew the friction of payment integration firsthand. Lucas: And they made a bet early on that I think was brilliant: they embraced Bitcoin in 2014.

Now, Bitcoin as a payment method didn’t take off, but that move signaled to developers that Stripe was innovative and willing to support new tech. Luna: It was a developer acquisition hack. Developers who played with Bitcoin integrations liked the Stripe API, then used it for their next project. That kind of low-cost, high-signal marketing is hard to replicate.

Lucas: And it feeds back into the network effect. The more developers use Stripe, the more integrations get built. There are now over 500 third-party integrations for Stripe, from accounting software to fraud detection. Each integration makes Stripe more valuable.

Luna: But there’s a risk, right? Stripe is dependent on the growth of internet commerce. If the economy slows, transaction volumes dip, and Stripe’s revenue takes a hit. Lucas: That’s true, but I’d argue Stripe’s business model is more resilient than a pure merchant acquirer.

Because they power platforms, they get paid on every transaction that flows through those platforms - whether it’s a ride, a delivery, or a SaaS subscription. The diversification of end-markets helps. Luna: And they’ve also moved upmarket. They now serve large enterprises like Salesforce and Amazon.

That requires more customization, but the revenue per customer is much higher. Lucas: Let’s talk about their competitive moat. Stripe’s brand with developers is extraordinary. They have a culture of developer experience that’s hard to copy.

Their documentation is famously excellent, and they’ve built tools like Stripe Radar for fraud detection. Luna: But competitors like Adyen and Square are also strong. Adyen has a unified platform for online and in-store. Square started with small businesses and moved up.

How does Stripe stay ahead? Lucas: One answer is global expansion. Stripe is available in over 40 countries, and they handle a lot of the complexity of local payment methods, compliance, and currency conversion. That’s a huge barrier to entry.

Luna: And they’re investing in new products. Stripe Tax, Stripe Billing, Stripe Capital - they’re layering more services on top of the payment rail. Each new product increases the switching cost for a business. Lucas: Yeah, let’s talk about the model through the lens of unit economics.

For every dollar Stripe processes, they keep about 2 to 3 percent. They have high fixed costs for engineering and compliance, but low marginal cost per transaction. So as volume scales, margins improve. Luna: Their estimated gross margin is around 70 percent, which is high for a payments company.

Compare that to traditional acquirers that might see 30 to 40 percent margins. That’s the power of a software-first approach. Lucas: And that’s the key insight: Stripe isn’t really a payments company. It’s a software company that happens to handle payments.

Their moat is code, not contracts. Luna: This is exactly the kind of show where I think the approach we take matters. We deliberately don’t run ads on these conversations, and that’s a choice. We want the focus to stay on the ideas, not on selling you something.

Lucas: Absolutely. And if you find these business model deep dives useful, if they’ve changed how you think about a company or even helped you in your own work, the link to support that choice is buy me a coffee dot com slash fexingo. Luna: It’s a low-key way to keep this ad-free. No pressure, but it’s there if you want to keep these episodes coming.

Lucas: So back to Stripe’s model. Another underappreciated element is their approach to platform risk. By serving many different verticals - retail, SaaS, marketplaces - they’re not reliant on any one sector. Luna: True, but they do have exposure to a few big platforms.

If Shopify decided to build its own payment processing in-house, that would be a blow. Lucas: That’s a real risk. But Shopify actually uses Stripe for its Shop Pay product, and building a full stack alternative would be expensive. Still, Stripe needs to keep those relationships strong.

Luna: Let me ask you this: what’s the one number that tells you Stripe’s business model is working? Lucas: I’d say the percentage of new businesses that choose Stripe without any sales interaction. It’s got to be over 80 percent. That’s the ultimate testament to product-led growth.

Luna: So the model is: build a product that developers love, let them spread it, then expand into adjacent services. Now they’re even offering banking as a service through Stripe Treasury. Lucas: Right. And that’s interesting because it turns Stripe into a platform for financial services.

Any company can now offer bank accounts, cards, and lending to its customers using Stripe’s infrastructure. That’s a huge expansion of the addressable market. Luna: It also creates more data for Stripe. They can see transaction patterns, lending risk, and cash flow trends.

That data can feed back into better fraud detection and credit scoring. Lucas: There’s a parallel to the WeChat model. WeChat started as messaging, then added payments, then added mini-programs. Stripe started as payments, then added financial services, now they’re adding business tools like Atlas and Issuing.

Luna: But WeChat is a consumer super app. Stripe is a business infrastructure layer. Different ends, similar logic of stacking services on a core transaction. Lucas: Exactly.

And the business model only works because the core payment service is sticky and has low churn. Once a business is integrated with Stripe, it’s painful to leave. You’d have to rewrite payment code, retrain staff, and potentially lose historical data. Luna: So the switching costs are high, which is why Stripe can introduce new products and see decent adoption.

It’s the classic platform play: attract users with a utility, then monetize through breadth. Lucas: And the value proposition for businesses is clear: one integration, many services. Instead of dealing with five different vendors for payment, tax, billing, and banking, you deal with Stripe. Luna: Is there a risk of Stripe becoming too big?

Regulators in Europe and the US are looking at big tech. Stripe is private, but if they go public, scrutiny will increase. Lucas: That’s a fair point. But Stripe’s business model has a built-in defense: they enable competition.

By lowering the barrier to start an online business, they help thousands of small businesses compete with incumbents. That’s a good story for regulators. Luna: And they’re not a bank. They partner with banks for the actual deposit accounts.

So they avoid some regulatory burdens. Lucas: Right. As of 2026, Stripe has been valued at over $60 billion. They’ve raised over $2 billion in funding.

The bet is that they can become the financial infrastructure for the entire internet economy. Luna: That’s a bet on the continued growth of e-commerce, SaaS, and the gig economy. All of which have tailwinds, but also face headwinds from regulation and competition. Lucas: True.

But I think Stripe’s biggest asset is its developer community. No other payment company has that. When a developer chooses Stripe, it’s not just a transaction - it’s a vote of confidence in the tooling and the ecosystem. Luna: So the lesson for other businesses is: if you can make your core product so good that users become evangelists, you don’t need a big sales team.

You need a great API and a culture of listening to developers. Lucas: And keep adding value on top. Every new service increases the switching cost and the revenue per customer. That’s the flywheel Stripe has been spinning for over a decade.

Luna: It’s a powerful model. And one that’s shaped the way we think about infrastructure businesses today. Lucas: Absolutely. Stripe proved that you can build a massive business by making yourself invisible - just the pipes that money flows through.

But those pipes are hard to replace.
