Tropic

Tropic charges an annual subscription based on the customer's software spend under management. The platform pays for itself through savings — if Tropic helps a company save $500,000 on software renewals, the subscription cost is a fraction of that.

Some pricing includes a success fee tied to actual savings achieved.

The value proposition is mathematically clear: Tropic typically saves customers 23% on their SaaS spending. For a company spending $5 million annually on software, that's $1.15 million in savings.

Tropic's subscription fee is a small percentage of those savings, making the ROI calculation trivially obvious.

The data moat grows with every customer. Each contract that flows through Tropic adds to their pricing benchmarks database, making their negotiation intelligence more accurate for future customers.

This is a classic network effect — the more companies use Tropic, the better it works for everyone.

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.

David Campbell spent years in SaaS sales and noticed something absurd: companies buying software almost never negotiated. They'd receive a quote, maybe push back slightly, and sign.

Meanwhile, the vendor knew exactly what discount they could offer because they had data from thousands of deals. The information asymmetry was massive — and it always favored the seller.

Campbell founded Tropic in 2020 to flip that asymmetry. The core insight was that if you aggregate pricing data from thousands of SaaS contracts across hundreds of companies, you can tell any buyer exactly what fair market price looks like.

Basically, "Company X is charging you $50 per user for this tier, but companies your size typically pay $32." That data-driven approach turns every negotiation from guesswork into science.

The timing was perfect. Post-COVID, companies were drowning in SaaS subscriptions.

The average mid-market company uses 100-200 software tools. CFOs started demanding visibility into software spend, and finance teams had no tools to manage it.

Tropic stepped into that gap with a platform that combined procurement automation with AI-powered negotiation intelligence.

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.

Tropic

Tropic grew by selling to CFOs with a message they couldn't resist: "we will literally save you more money than we cost." In a market where every other tool adds to the tech stack cost, Tropic reduces it. That positioning is powerful during economic downturns when CFOs are cutting budgets.

Customer success stories spread quickly. When a finance leader saves $500K on software renewals using Tropic, they tell other finance leaders.

The procurement community is tight-knit, and word travels fast at CFO conferences and finance Slack communities.

The managed services component creates stickiness. Tropic doesn't just provide data — their negotiators handle the actual vendor conversations.

This "done for you" model means customers don't need internal procurement expertise. Once Tropic handles your renewals, bringing the function in-house again feels like a downgrade.

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 procurement software market is getting crowded. Vendr, Zylo, Productiv, and Sastrify all target SaaS spend management from different angles.

Differentiation is challenging when every vendor claims to save customers money on software purchases.

Scaling the negotiation services team is operationally complex. Unlike pure software companies that scale with zero marginal cost, Tropic's managed negotiation service requires trained humans.

Each new customer needs real people conducting real vendor negotiations. Balancing human-led services with AI automation is an ongoing challenge.

Vendor pushback is real. As procurement platforms become more common, SaaS vendors are adjusting their pricing strategies to account for aggressive negotiation.

Some vendors have started offering "non-negotiable" pricing tiers or adjusting discount structures. The more successful Tropic becomes, the more vendors adapt their tactics.

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.

Insight Partners led the Series B. Canapi Ventures was an early investor.

8VC and other venture firms participated in growth rounds. The company has raised approximately $105 million total across multiple rounds.
