Compare / Spring Health vs Stripe
AT A GLANCE
FUNDING HISTORY
Spring Health
Stripe
BUSINESS MODEL
Spring Health
B2B employer benefit — similar model to Lyra Health but with a sharper focus on precision matching. Companies pay Spring Health a per-employee-per-month fee.
Employees take an initial assessment and Spring Health's algorithm recommends a care pathway: therapy, medication management, coaching, digital self-care, or a combination. The key differentiator is the precision — the algorithm claims to reduce treatment time by 50% by getting the right match first instead of cycling through options.
Spring Health also provides a therapist network, psychiatric services, and crisis support. Revenue scales with employer contracts and employee utilization.
Stripe
Stripe charges a flat 2.9% + $0.30 per transaction. That's it.
No setup fees, no monthly fees, no hidden charges. The simplicity is the product.
When a customer pays on a website using Stripe, Stripe handles everything — fraud detection, currency conversion, bank transfers, tax calculation, compliance. The merchant just sees money arrive in their account.
On top of the core payments, Stripe has built an entire financial infrastructure stack. Billing for subscriptions, Connect for marketplace payments, Atlas for incorporating a company, Issuing for creating virtual cards, Treasury for banking-as-a-service, and Radar for fraud prevention.
They're basically building the financial plumbing for the entire internet.
HOW THEY STARTED
Spring Health
April Koh was studying computational neuroscience at Yale when she encountered research on precision medicine for depression — the idea that you could use data to predict which patients would respond to therapy versus medication versus a combination. The existing system was essentially trial and error: try an antidepressant for six weeks, and if it doesn't work, try another one.
Meanwhile, patients suffer. Koh co-founded Spring Health in 2016 with Adam Chekroud, a Yale neuroscience PhD, to build a platform that uses machine learning to match employees to the right mental health treatment on the first try.
They started by publishing peer-reviewed research showing their algorithms could predict treatment response better than chance, then turned that research into a product that employers would pay for.
Stripe
Patrick Collison was 19. His brother John was 17.
They had already built and sold a company — Auctomatic, an eBay auction tool — for $5 million while still teenagers in Limerick, Ireland. Patrick went to MIT, John went to Harvard, and they both dropped out because they had a better idea.
The idea was embarrassingly obvious in hindsight. In 2010, accepting payments on the internet was a nightmare.
You had to get a merchant account, negotiate with a payment processor, deal with a gateway provider, handle PCI compliance, and write thousands of lines of code. It took weeks or months.
The Collisons thought it should take five minutes.
They built a simple API — seven lines of code — that let any developer start accepting credit card payments immediately. No merchant account.
No paperwork. No phone calls with banks.
Just paste seven lines of code and you're in business. They originally called it /dev/payments, then changed it to Stripe in 2011.
Peter Thiel and Elon Musk — the PayPal mafia — were among the first investors. Sequoia and Andreessen Horowitz piled in soon after.
The Collisons had built exactly what every developer on Earth had been wishing for.
HOW THEY GREW
Spring Health
Enterprise sales to large employers, competing directly with Lyra Health, Headspace Health, and traditional EAP providers. Spring Health leads with outcomes data — publishing research showing faster recovery times and higher clinical improvement rates than industry benchmarks.
Celebrity advisor Apolo Ohno and high-profile board members gave early credibility. Series C at $2.5 billion valuation generated press coverage that opened doors.
International expansion to serve global workforces. Strategic investment from Kinnevik gave European distribution relationships.
Partnership with health plans to offer Spring Health as the behavioral health component within existing benefits.
Stripe
Stripe grew almost entirely through developer love. They didn't hire a sales team for years.
They didn't run ads. They just built the best developer documentation anyone had ever seen and let word of mouth do the rest.
The developer-first strategy was deliberate. The Collisons realized that in a startup, the developer usually decides which payment provider to use.
If you make the developer happy, you win the company. Stripe's API documentation became legendary — clear, beautiful, with working code examples in every language.
They also grew by growing with their customers. Early Stripe customers included tiny startups that later became giants — Lyft, DoorDash, Instacart, Shopify.
As those companies scaled to billions in revenue, Stripe's processing volume scaled with them. Stripe didn't need to acquire new customers because its existing ones kept getting bigger.
The international expansion was methodical. Instead of launching everywhere at once like Uber, Stripe carefully added country after country, making sure each one worked perfectly with local payment methods, currencies, and regulations.
By 2024 they were processing payments in 195 countries.
THE HARD PART
Spring Health
Direct competition with Lyra Health, which is larger and better-funded. The employer mental health benefit space is crowded and increasingly commoditized — every startup claims better outcomes and faster ROI.
Therapist supply is the binding constraint across the entire industry. Proving that ML-driven matching actually produces better outcomes than simply having a good therapist network is a difficult clinical claim to substantiate at scale.
Employee engagement is everything — if employees don't take the initial assessment, the precision matching engine can't work. And the macro headwind: employer benefits budgets are under pressure, and mental health benefits are easier to cut than medical benefits when money gets tight.
Stripe
Valuation whiplash. In 2021, Stripe hit a peak valuation of $95 billion during the fintech boom.
By 2023, they had to mark it down to $50 billion during the tech correction — a 47% drop that made headlines everywhere. Employees who had been paper millionaires suddenly weren't.
The valuation has since recovered to $91 billion after a secondary share sale in 2025, but those two years were rough for morale.
Competition is relentless. Adyen, the Dutch payments company, has been eating into Stripe's enterprise market.
Square (now Block) competes on the small business side. PayPal is everywhere.
New fintech players pop up constantly. The payments business has razor-thin margins and everyone is fighting for the same 2.9%.
Going public is the elephant in the room. Stripe has been expected to IPO for years.
Investors, employees, and the media keep asking when. The Collisons have consistently said they're in no rush, but with $8.7 billion raised and thousands of employees holding stock options, the pressure to provide liquidity is enormous.
As of 2025, they've opted for secondary sales instead of a public offering.
