AT A GLANCE
FUNDING HISTORY
Wiz
Klarna
BUSINESS MODEL
Wiz
Wiz sells annual subscriptions based on the number of cloud workloads (virtual machines, containers, serverless functions) protected. Pricing scales with cloud consumption — as customers use more cloud, they pay Wiz more.
This aligns perfectly with the broader trend of growing cloud spend.
The agentless model is a key pricing advantage. Traditional security tools require installing software agents on every server, which creates deployment costs, performance overhead, and maintenance burden.
Wiz connects via API to cloud provider accounts and scans everything externally. Deployment takes minutes instead of months, which dramatically shortens the sales cycle.
ARR growth was record-breaking: $1 million within months of launch, $100 million in 18 months, $350 million by 2023, and reportedly over $500 million by 2024. No enterprise SaaS company has ever scaled this fast.
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
Wiz
The four Wiz co-founders — Assaf Rappaport, Ami Luttwak, Yinon Costica, and Roy Reznik — had already built and sold a cybersecurity company together. Their previous startup, Adallom, was a cloud security company that Microsoft acquired in 2015 for $320 million.
After the acquisition, all four worked at Microsoft leading the Cloud Security Group.
By 2020, they were ready to leave and build again. They saw a gap in cloud security: as companies rushed workloads to AWS, Azure, and Google Cloud, security tools hadn't kept pace.
Existing solutions required installing agents on every server and generated floods of alerts that security teams couldn't process. The cloud was a mess of misconfigurations, exposed credentials, and hidden vulnerabilities — and nobody had a clear picture of it all.
Wiz launched in January 2020 — literally weeks before COVID-19 shut the world down. Instead of slowing them, the pandemic accelerated their market.
Every company on Earth was rushing to the cloud, and Wiz's agentless approach meant customers could deploy it in minutes with zero infrastructure changes. Connect your cloud account, and Wiz scans everything — VMs, containers, serverless functions, databases, identity configurations — building a complete risk map.
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
Wiz
Wiz grew through a combination of product excellence and founder credibility. The four co-founders had already sold a company to Microsoft and led cloud security there.
When they said "we built a better way," CISOs believed them because of the track record.
The product sold itself through demonstrations. Wiz's 15-minute deployment — connect your cloud account, see your risk map immediately — was the most effective sales tool.
Security vendors typically require weeks or months of setup. Wiz showed results in a single meeting.
Landing massive logos early created a cascade. Within two years, Wiz had 40% of the Fortune 100 as customers.
When one CISO at a major bank buys Wiz, every other bank CISO hears about it. Enterprise security is a trust-based market, and early customer logos created a self-reinforcing credibility loop.
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
Wiz
The Google acquisition decision dominated 2024. Wiz turned down Google's $23 billion offer in July 2024, with Rappaport saying they wanted to pursue an IPO and build an independent company.
Then they accepted a $32 billion offer later — the largest cybersecurity acquisition in history. The deal raised questions about cloud neutrality: Wiz secures AWS, Azure, and GCP equally, but becoming owned by Google could make AWS and Azure customers nervous.
Before the acquisition, the competitive landscape was intensifying. Palo Alto Networks acquired cloud security startups aggressively.
CrowdStrike expanded from endpoint security into cloud. AWS, Azure, and Google all improved their native security tools.
Wiz's lead was real but competitors were closing in.
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.

WHO BACKED THEM
Wiz
