Compare / Grow Therapy vs Klarna
AT A GLANCE
FUNDING HISTORY
Grow Therapy
Klarna
BUSINESS MODEL
Grow Therapy
Two-sided marketplace for mental health. Therapists join Grow Therapy's network and the company handles insurance credentialing, claims billing, scheduling, and compliance.
In return, Grow Therapy takes a percentage of each session's insurance reimbursement. Patients search Grow Therapy's directory to find in-network therapists by specialty, insurance plan, and availability.
The therapist gets to focus on therapy. The patient gets affordable care.
Grow Therapy gets a cut for handling the business side. Everyone wins except the old credentialing companies that charged therapists thousands of dollars to do what Grow Therapy does for free.
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
Grow Therapy
Jake Cooper was working in healthcare operations when he saw the same problem from both sides. Patients couldn't find therapists who accepted their insurance.
Therapists wanted to accept insurance but the credentialing process took 6 to 12 months and the billing was a bureaucratic disaster. Most therapists just went cash-pay to avoid the headache, which meant only people who could afford $200 a session got care.
Cooper started Grow Therapy in 2020 to solve the plumbing problem. Not the clinical side — the administrative infrastructure that makes it possible for a therapist to see an insured patient without losing their mind.
He launched right as the pandemic made therapy demand explode and supply couldn't keep up.
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
Grow Therapy
Supply-side acquisition — recruit therapists by solving their biggest pain point (insurance credentialing) for free. Once therapists are in-network through Grow Therapy, patients find them through the directory.
The company expanded insurance partnerships aggressively, getting in-network with Aetna, Cigna, UnitedHealthcare, Anthem, and dozens of regional plans. State-by-state expansion tracking licensing requirements.
Content marketing targeting therapists frustrated with private practice admin. Referral loops from satisfied therapists bringing colleagues onto the platform.
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
Grow Therapy
Insurance reimbursement rates for therapy are low and getting lower in some states. Grow Therapy's margin depends on volume because per-session economics are thin.
Keeping therapists on the platform once they're credentialed is a retention challenge — some therapists use Grow Therapy to get credentialed, then leave to handle billing themselves. Competition from Headway, Alma, and others doing similar things means the race to sign up therapists is intense.
Quality control across 10,000+ providers is a real concern. And the fundamental tension remains: insurance companies want to pay less per session, therapists need to earn enough to survive, and Grow Therapy sits in the middle trying to make both sides happy.
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.
