BUSINESS MODEL

Notion

Notion uses freemium pricing. The free plan is generous — unlimited pages and blocks for individuals.

The Plus plan is $10/user/month for small teams. Business is $18/user/month.

Enterprise is custom-priced. The free tier is intentionally powerful enough that individuals and small teams can use it forever without paying.

The revenue comes when those individuals bring Notion to their companies and entire organizations adopt it.

Notion also has an AI add-on at $10/member/month that adds AI writing assistance, summarization, and Q&A across your workspace.

Klarna

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.

HOW THEY STARTED

Notion

Ivan Zhao studied cognitive science at the University of British Columbia, obsessed with the idea that computers should be creative tools, not just consumption devices. He was inspired by pioneers like Alan Kay and Douglas Engelbart who envisioned computers as tools for thought.

In 2013, he started Notion with the idea of building a tool that combined documents, databases, and project management into one flexible workspace.

The first version of Notion launched in 2015 and basically nobody cared. The product was too abstract.

People didn't understand what it was or why they needed it. The company burned through its initial funding.

By 2015, Notion was nearly dead — Zhao had to lay off almost the entire team.

With the last of his money, Zhao kept just one engineer — Simon Last — and moved to Kyoto, Japan, where the cost of living was a fraction of San Francisco. For over a year, Zhao and Last rebuilt Notion from scratch in a tiny apartment.

They rewrote the entire product, making it simpler and more intuitive. The 2.0 version launched in March 2018.

This time, it clicked. Product Hunt loved it.

Twitter loved it. Within months, Notion was growing 50% month over month.

Klarna

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.

HOW THEY GREW

Notion

Notion grew almost entirely through organic love. The product was so flexible that users built incredible things with it and shared them on Twitter, YouTube, and Reddit.

Template creators built entire businesses around selling Notion templates. YouTubers made "my Notion setup" videos that got millions of views.

Notion didn't need a marketing team because its users were the marketing team.

The template ecosystem was a massive growth driver. Notion made it easy to duplicate and share templates.

Productivity influencers and creators built elaborate systems — life dashboards, second brains, CRM systems, content calendars — and shared them with their audiences. Every shared template was a free advertisement for Notion.

The community strategy was deliberate. Notion hired community managers early and empowered super-users to become Notion ambassadors.

There are Notion meetups in cities worldwide. Notion Campus Leaders run groups at universities.

The company understood that for a tool this flexible, community was the best way to teach people what's possible.

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.

THE HARD PART

Notion

The "too flexible" problem. Notion can do almost anything, which means new users often stare at a blank page and have no idea where to start.

The learning curve isn't steep, but it's wide. People give up before discovering the product's power.

Every Notion user remembers the moment it finally "clicked" — but many potential users never reach that moment.

Enterprise adoption has been slower than expected. Notion is beloved by startups and small teams, but large enterprises need things like advanced permissions, audit logs, compliance certifications, and admin controls.

Building enterprise features while keeping the product simple for individuals is a constant tension. Companies like Confluence (Atlassian) have decades-long enterprise relationships that are hard to displace.

Performance at scale has been a persistent complaint. Notion pages with hundreds of blocks or large databases can become sluggish.

The app has improved significantly but power users with massive workspaces still hit performance walls. For a tool that promises to replace multiple apps, it needs to be as fast as each individual app it replaces.

Klarna

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.

THE PRODUCTS

Notion

Notion is a workspace that combines notes, docs, wikis, project management, and databases into one tool. Pages can contain any mix of text, tables, kanban boards, calendars, galleries, and embedded content.

Notion Databases are the power feature — structured data that can be viewed as tables, boards, timelines, or calendars. Templates let users start with pre-built setups for everything from CRM to habit tracking.

Notion AI adds writing assistance, summarization, and the ability to ask questions about your workspace content. Notion Sites turns any Notion page into a published website.

Klarna

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.
