DoorDash

DoorDash operates a three-sided marketplace connecting restaurants, delivery drivers (Dashers), and consumers. Revenue comes from three streams: commissions charged to restaurants (typically 15-30% of the order value), delivery fees and service fees charged to consumers, and DashPass subscription revenue ($9.99/month for free delivery and reduced fees).

The DashPass subscription is the retention engine. Over 18 million subscribers pay monthly whether they order or not, creating predictable recurring revenue.

Subscribers order more frequently (about 4x more than non-subscribers), increasing order volume.

Advertising is the emerging high-margin business. Restaurants pay for promoted listings and sponsored placements in the app.

This is essentially a search advertising business built on top of a logistics network. Ad revenue has grown to over $1 billion annually — and it's nearly pure profit because it costs almost nothing to display an ad.

Klarna makes money from merchant fees and consumer interest. Merchants pay Klarna 3-6% of each transaction — they're willing to pay because Klarna increases conversion rates by 30%+ and average order values by 45%.

On "Pay in 4" (interest-free installments), Klarna makes money purely from merchant fees. On longer financing (6-36 months), Klarna charges consumers interest up to 25% APR.

Klarna also earns revenue from its shopping app (affiliate commissions when users discover and buy from merchants), and from its Klarna Card.

Tony Xu grew up watching his mother work multiple restaurant jobs after the family immigrated from Nanjing, China to Illinois. She washed dishes, waited tables, and cooked — sometimes all in the same week at different restaurants.

That experience gave Xu an unusual understanding of how brutally hard the restaurant business is.

At Stanford in 2012, Xu and classmates Stanley Tang, Andy Fang, and Evan Moore were in a startup class looking for a business idea. They interviewed over 200 small business owners and kept hearing the same problem: restaurants wanted to offer delivery but couldn't afford to hire drivers.

Domino's and Pizza Hut had fleets. Your local Thai place didn't.

Their solution was comically low-tech. They built a one-page website called PaloAltoDelivery.com, listed menus from local restaurants (without asking permission), and put their personal phone numbers on the site.

When orders came in, they drove the food themselves. The first order was pad thai from a restaurant in Palo Alto.

Within months, they were drowning in orders and realized this was a massive business. They incorporated as DoorDash in January 2013 and got into Y Combinator that summer.

Sebastian Siemiatkowski, Niklas Adalberth, and Victor Jacobsson were students at the Stockholm School of Economics. In 2005, they entered a startup competition with an idea: let people buy things online and pay later.

At the time, online shopping was still new and most people were terrified of entering their credit card details on the internet. The idea was simple — Klarna would pay the merchant immediately, and the customer would get an invoice with 14-30 days to pay.

The competition judges hated it. The idea was dismissed as financially irresponsible and the team didn't win.

But Siemiatkowski pressed on. Swedish e-commerce was growing fast and merchants were desperate for any way to reduce cart abandonment.

Klarna's "pay after delivery" model was a hit because it shifted the risk — customers could receive the product, try it on, and only pay for what they kept.

The first customers were Swedish e-commerce merchants selling fashion and home goods. Klarna handled the invoicing, fraud detection, and collections.

Merchants saw conversion rates jump because customers were more willing to buy when they didn't have to pay immediately.

DoorDash

DoorDash won the US market through obsessive focus on suburban and mid-market restaurants — the segments Uber Eats and Grubhub ignored. While competitors fought over Manhattan and San Francisco, DoorDash was onboarding every Chinese restaurant and pizza shop in Tucson and Des Moines.

By the time competitors noticed, DoorDash had locked up the majority of US restaurants.

The "last-mile logistics" expansion is the long game. DoorDash now delivers groceries (partnerships with Albertsons, Rite Aid), convenience items (DashMart dark stores), alcohol, pet supplies, and retail products.

The thesis is that once you have a network of drivers and a consumer habit of ordering through an app, you can deliver anything — not just food.

The Wolt acquisition for $8.1 billion in 2022 was the international play. Instead of grinding through country-by-country expansion, DoorDash bought the leading delivery platform in 23 countries across Europe and Asia.

Wolt brought strong unit economics and a beloved brand, especially in the Nordics.

Klarna

Klarna grew by being embedded at checkout. The strategy was to sign up the biggest online retailers and become a payment option alongside Visa and PayPal.

Once Klarna was at checkout, consumers discovered it organically. The "Pay in 4" button became ubiquitous across fashion, electronics, and home goods retailers.

The Klarna app became a growth engine beyond checkout. By building a shopping app where users could browse products, discover deals, and track deliveries, Klarna turned from a payment method into a shopping destination.

The app has 35+ million monthly active users who start their shopping journey inside Klarna before even visiting a retailer.

International expansion was aggressive. Starting in Sweden, Klarna rolled out across Europe, then into the US, UK, and Australia.

The US became the biggest growth market — American consumers were especially receptive to Pay in 4 as an alternative to credit cards. By 2023, Klarna had 34 million US users.

Profitability has been the constant question. DoorDash lost money every year through its IPO and beyond, finally turning consistently profitable in 2023.

The food delivery business has razor-thin margins — restaurants want lower commissions, drivers want higher pay, and consumers want lower prices. Squeezing profit from that three-way tension is incredibly hard.

Regulatory risk is real and growing. Cities and states have capped delivery commissions (New York City caps at 15% for delivery, 5% for marketing).

Worker classification lawsuits keep coming — are Dashers employees or independent contractors? California's Prop 22 temporarily settled this for California, but the debate rages everywhere else.

Each new regulation shaves margin.

Uber Eats is the forever competitor. Uber's massive ride-sharing network gives them built-in driver supply and brand recognition.

They're willing to lose money on Eats to keep their broader ecosystem sticky. DoorDash and Uber Eats together control about 90% of US delivery, and neither can afford to cede ground.

The valuation collapse was humiliating. Klarna raised at a $46 billion valuation from SoftBank in 2021.

One year later, they raised a down round at $6.7 billion — an 85% haircut. It was the most dramatic valuation drop in fintech history.

Employee stock options were underwater. Siemiatkowski had to lay off 10% of the workforce.

The entire BNPL category went from hot to radioactive in months.

Credit losses are the existential risk. Klarna is lending money to consumers who want to buy things they can't afford to pay for right now.

When the economy slows, defaults rise. Klarna's credit losses hit $1 billion in 2022.

The company had to tighten underwriting significantly and pull back from riskier markets. The tension between growth (approve more loans) and profitability (reject risky borrowers) defines every quarter.

The IPO in 2025 was a comeback story but with caveats. Klarna went public at $15 billion — a major recovery from the $6.7 billion trough but still less than a third of its 2021 peak.

The company finally turned profitable by slashing costs with AI (replacing hundreds of customer service agents with AI chatbots) and tightening credit standards. But investors remain cautious about the BNPL model's long-term sustainability.

DoorDash

DoorDash Marketplace — the core food delivery platform connecting consumers to 390,000+ restaurant partners across the US, Canada, Australia, Japan, and Germany. DashPass — a subscription program offering $0 delivery fees and reduced service fees for $9.99/month.

The loyalty engine of the entire business. DoorDash Drive — a white-label delivery service that lets any business (not just restaurants) use DoorDash's driver network to fulfill their own orders.

Basically DoorDash as a logistics API. DoorDash for Business — a corporate platform for team meals, employee benefits, and office food programs.

Wolt — the European food delivery platform DoorDash acquired for $8.1 billion in 2022, now the company's international expansion vehicle.

Pay in 4 is the signature product — split any purchase into four interest-free payments over six weeks. Pay in 30 lets customers receive the product first and pay within 30 days.

Financing offers longer-term payment plans with interest for larger purchases. The Klarna App is a shopping destination — browse deals, track orders, manage payments, and earn cashback.

The Klarna Card is a physical Visa card that lets users Pay in 4 anywhere. Klarna Creator is a platform for influencers to earn commissions sharing products.

Klarna AI is their customer service chatbot that handles two-thirds of support queries.

Sequoia Capital has been the most consequential investor, leading multiple rounds and backing Tony Xu from Y Combinator onward. Khosla Ventures, Kleiner Perkins, and SoftBank Vision Fund participated in growth rounds.

Y Combinator was the starting point (Summer 2013 batch). The December 2020 IPO raised $3.4 billion at a $39 billion valuation, making it one of the biggest tech IPOs of that year.
