Most fintech companies treat marketing as a cost of acquiring users. Klarna treats it as three things at once: a brand weapon, a production line it automated with AI, and a business unit that sells advertising back to the merchants it serves. That third one is the part the case studies keep missing.
Klarna’s marketing strategy is a payments network strategy built on four pillars: a deliberately un-bank-like consumer brand (“Smoooth”), an AI-run creative production stack that cut agency and image costs by roughly $10 million a year, a retention model that grows revenue per user rather than user count, and an advertising business that sells the attention of Klarna’s shopping app back to merchants. Klarna markets to consumers, to merchants, and, since 2026, to the AI agents that increasingly do the shopping.
Klarna Group plc (NYSE: KLAR) listed on the New York Stock Exchange in September 2025 at $40 a share and a $15.1 billion valuation. By the first quarter of 2026 it was reporting $1.01 billion in quarterly revenue, 119 million active consumers and more than 1 million merchants. The marketing machine behind those numbers looks nothing like the one a traditional bank runs, and understanding why is more useful to an operator than another recap of the Snoop Dogg ad.
Klarna Markets to Two Audiences, Not One
Klarna is a two-sided network. Consumers need to want the payment button, and merchants need to pay to install it. A campaign that wins one side and bores the other is worthless.
In the first quarter of 2026, Klarna’s consumer base grew 21% year over year while its merchant base grew 49%. Merchant supply is compounding faster than consumer demand, which is the correct shape for a network like this one. More merchants means more places the button appears, which means more reasons for a consumer to keep the app installed, which makes the button more valuable to the next merchant.
Consumer marketing at Klarna exists to give merchant sales a reason to be easy. Sebastian Siemiatkowski has been open about this: the celebrity work was never about direct response.
The Brand Pillar: Being the Least Boring Company in Finance
David Sandström joined Klarna as CMO in 2017 with a mandate from Siemiatkowski to rebuild the brand around something other than trust signals and blue gradients. The team ran the rebrand backward, starting from the checkout button and working outward, which is why Klarna’s pink shows up as a payment option before it shows up as a logo.
The campaign work that followed was designed for press pickup, not click-through:
| Campaign | Year | Mechanic | Why it worked |
|---|---|---|---|
| Get Smoooth (Snoop Dogg as “Smoooth Dogg”) | 2019 | Rapper renamed himself, took equity, starred in DDB Stockholm films | Equity stake turned an endorsement into a business story, so finance press covered a marketing campaign |
| Smoooth product drops | 2019 | Golden peanut butter, cashmere toilet paper, a 22-foot inflatable slide | Physical absurdity gave publications something to photograph |
| Lady Gaga and A$AP Rocky partnerships | 2020 to 2021 | Culture-first creative, US market entry | Bought relevance with a US audience that had never heard of a Swedish invoicing company |
| Klarna Card everyday-spend push | 2025 to 2026 | Product marketing, no celebrity | Repositioning from shopping toy to daily wallet |
The Snoop deal is the one worth studying. Klarna gave a rapper a minority stake and got Forbes, Business Insider, Ad Age and The Drum covering the same campaign from four different angles. That is not a media buy. That is a story engineered to be free.
The strategic cost is real, though. A brand built on “smoooth” spending sits directly under a regulatory microscope aimed at consumer debt. Klarna spent 2023 to 2026 quietly walking the brand toward “bank,” and the celebrity era has not returned.
The AI Pillar: Klarna Rebuilt Marketing Production, Not Marketing Strategy
Klarna became the most-cited corporate case study in generative AI marketing, and most of the citations get the point backward. The company did not use AI to invent campaigns. It used AI to demolish the cost of producing them.
The reported numbers: a $6 million reduction in image production costs, a $4 million run-rate saving on external translation, production, CRM and social agencies, a 25% cut in external marketing supplier spend, and an image development cycle compressed from six weeks to seven days. Klarna generated more than 1,000 images with Midjourney, DALL-E and Firefly in a single quarter, and drafts around 80% of its marketing copy with an internal tool called Copy Assistant. Roughly 37% of total marketing and sales savings came from AI, worth about $10 million annualized.
The operator lesson sits in what Klarna did with the money. Sandström redirected savings from “non-working” spend (agencies, translation, production) into “working” spend (paid media). The AI did not shrink the marketing budget. It changed the ratio inside it.
The trap here is obvious and worth naming. Klarna operates in 26 markets with three products and a huge volume of repetitive, low-creativity localization work. That is close to the ideal case for generative production. A brand running two campaigns a year in one language will not find $10 million hiding in its image budget.
The Retention Pillar: Klarna Sells Depth, Not Signups
Klarna’s marketing incentives changed the moment the company decided it wanted to be a bank rather than a checkout button. Acquiring a Pay in 4 user is cheap. Getting that user to hold a Klarna Card, park deposits and finance a sofa is where the money is.
Klarna disclosed the cleanest version of this in its Q1 2026 shareholder letter. Consumers who first used Klarna in 2022 generated $12 in annual revenue in year one. That same cohort now generates $52 a year. The Klarna Card passed 5 million active users across 16 countries, and Fair Financing volume grew 138% year over year to $4.1 billion in a single quarter.
The marketing job that follows is cross-sell, not conversion. Klarna’s app, its push notifications and its home feed do the work that a performance agency would otherwise be paid to do through paid social. Sandström once said his long-term goal was to overhear two people on the street discussing Klarna’s push notifications. That is a retention metric disguised as a brand ambition.
The Money Pillar: Klarna Sells Ads Back to Its Merchants
Klarna’s IPO filing forced a disclosure that changes how you should read the whole strategy. In 2024, Klarna earned $180 million from advertising services sold to merchants, roughly 6% of its $2.81 billion in revenue.
Klarna sells three formats: sponsored search placements inside app search results, an affiliate program that gives a merchant a full product carousel in a consumer’s home feed, and programmatic brand ads that open Klarna’s audience data to third-party advertisers. The company claims it is addressing a $475 billion global digital advertising market.
The strategic logic is the same one Amazon ran a decade earlier. A shopping app collects browsing, search and transaction data. Merchants will pay for placement in front of a shopper whose intent is documented and whose payment method is already loaded. Klarna’s marketing department produces the audience. Klarna’s ad business monetizes it a second time, at a margin the lending business cannot match.
Klarna also gave merchants tools to run their own campaigns through Ads Manager, plus Creator Shops for influencers. Every merchant who learns to buy Klarna ads becomes harder to remove from the checkout page.
The Distribution Pillar: Marketing to Machines
The newest shift in Klarna’s strategy is the one most brands have not started. Klarna is placing its brand inside the AI assistants where product discovery is moving.
In May 2026, Klarna launched a Shopping Search app inside ChatGPT, connecting OpenAI’s assistant to a catalog of more than 100 million products and 400 million merchant listings across 13 markets, powered by Klarna’s own Product Search MCP server. Klarna also joined Google’s Universal Commerce Protocol and now appears as a payment option at checkout inside the Gemini app and Google Search via Google Pay.
Adobe reported that traffic from AI platforms to retail sites grew close to 700% during the 2025 holiday season, with those visitors converting at a higher rate. Klarna is treating the assistant window as the next shelf, and it bought the shelf early. The PriceRunner acquisition, and the $1.97 billion antitrust judgment Klarna won against Google in Stockholm in July 2026, gave it the structured product catalog that makes the shelf worth owning.

Where the Strategy Is Vulnerable
Three weak points deserve honest attention.
The brand and the regulator are pulling in opposite directions. “Smoooth” was designed to make borrowing feel frictionless. Consumer credit regulators in the UK, the EU and the US have spent five years arguing that frictionless borrowing is the problem. Klarna cannot run the 2019 playbook again.
The AI savings story has a ceiling. You can only remove the agency line item once. Klarna’s marketing cost curve gets harder from here, and investors who bought the “AI cuts costs forever” narrative at IPO have already repriced the stock well below its $40 debut.
Owning the AI shelf is not the same as owning the customer. Klarna does not control ChatGPT or Gemini. It rents placement there, exactly as merchants rent placement inside Klarna’s app. The company built a business on being the intermediary and is now, in agentic commerce, on the other side of that trade.
FAQ
What is Klarna’s marketing strategy? Klarna markets to consumers with a deliberately playful, un-bank-like brand, markets to merchants with conversion and advertising tools, and markets to AI agents by embedding its product catalog and payment options inside assistants like ChatGPT and Gemini. Its creative production runs largely on generative AI, and its advertising business turns marketing into a revenue line worth $180 million in 2024.
Who is Klarna’s target audience? Millennial and Gen Z online shoppers are the core consumer segment, with the Klarna Card and deposit products pushing the brand toward broader everyday banking. On the merchant side, the target is any retailer that wants higher checkout conversion, from Walmart-scale accounts to small e-commerce brands.
How much does Klarna spend on marketing? Klarna does not break out a public marketing budget line. It has disclosed that generative AI cut roughly $10 million a year from marketing and sales costs, including $6 million in image production and a $4 million run rate on external suppliers, and that it reduced external marketing supplier spend by 25%.
Why did Klarna partner with Snoop Dogg? Klarna wanted press coverage rather than clicks. Making Snoop Dogg a minority shareholder as well as the campaign’s face turned a marketing stunt into a financial news story, earning coverage across business, entertainment and advertising media at once.
How does Klarna make money from advertising? Klarna sells sponsored search placements in its app, affiliate carousels in the consumer home feed, and programmatic brand ads built on its browsing and transaction data. That business generated $180 million in 2024, about 6% of total revenue.
The Business Model Analyst Take
Klarna’s marketing strategy is worth studying because it inverts the usual relationship between marketing and the business model. At most companies, marketing spends money to feed the product. At Klarna, marketing built an audience, and the company then sold access to that audience back to the merchants it was already charging for payments. The same 119 million consumers get monetized twice.
The Snoop Dogg campaign gets the attention, and the AI savings get the LinkedIn posts, but the durable lesson sits in the ad business. Klarna proved that a payments company with an app and intent data is one product decision away from becoming a media network. Any founder with a high-frequency consumer app and a merchant relationship on the other side should be doing that math.
The open question is whether Klarna can hold the shelf. Its brand was built for a world where people browsed. Its future depends on a world where agents browse for them, and in that world Klarna is a supplier to OpenAI and Google rather than the owner of the storefront. The company that made its name by removing friction now needs to prove it can survive a checkout it does not control.
