Anthropic

Anthropic makes money through API access and subscriptions, similar to OpenAI. The Claude API charges developers per token for input and output.

Claude Pro costs $20/month for individuals with priority access and higher usage limits. Claude Team is $25-30/user/month for businesses.

Claude Enterprise offers custom pricing with enhanced security, admin controls, and longer context windows. Amazon Web Services resells Claude through Amazon Bedrock and Google Cloud offers it through Vertex AI, both generating revenue-sharing income for Anthropic.

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.

Anthropic

Dario Amodei was VP of Research at OpenAI. His sister Daniela Amodei was VP of Operations.

They were two of the most senior people at the company. In 2020-2021, they grew increasingly concerned that OpenAI was prioritizing commercialization over safety research.

The board crisis that would eventually happen in 2023 was already brewing beneath the surface — the tension between "move fast and ship products" and "slow down and do the safety work" was real.

In early 2021, Dario and Daniela left OpenAI and took a group of key researchers with them. They founded Anthropic as a public benefit corporation — a structure that legally requires the company to consider its impact on society, not just shareholder returns.

The name comes from "anthropic principle" in physics — the idea that the universe's fundamental parameters seem fine-tuned for human existence.

The founding thesis was simple: AI was going to become incredibly powerful whether anyone wanted it to or not. The safest path was to have a safety-focused lab at the frontier of capabilities, not watching from the sidelines.

Build the most powerful AI you can, but build it with safety baked into every layer.

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.

Anthropic

Anthropic grew through a deliberate "safety as a brand" strategy. While OpenAI chased consumer virality with ChatGPT, Anthropic positioned Claude as the thoughtful, reliable, safety-conscious alternative.

Developers who found ChatGPT inconsistent or who worried about data privacy gravitated to Claude.

The enterprise partnerships were the real growth engine. Amazon invested $4 billion and made Claude the featured AI on Amazon Bedrock.

Google invested $2 billion and integrated Claude into Google Cloud. These partnerships gave Anthropic instant distribution to millions of enterprise developers without building a sales team.

Claude's strength in specific use cases drove adoption. Claude became known as the best AI for long-document analysis, nuanced writing, and careful reasoning.

Law firms, financial analysts, researchers, and enterprise customers who needed accuracy over speed chose Claude. The reputation for quality over flash built a loyal and growing user base.

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.

Anthropic

The funding arms race is existential. Training frontier AI models costs billions.

Anthropic has raised $13.7 billion and needs to keep raising because each generation of Claude costs more to train. If a funding round fails or investors lose confidence, Anthropic can't compete at the frontier.

The company is in a spending war with OpenAI (backed by Microsoft) and Google (with DeepMind) — two of the richest companies in history.

Being second in consumer awareness hurts. ChatGPT is a household name.

Claude is not. Most non-technical people have never heard of Anthropic.

This matters because consumer brand recognition drives enterprise adoption — CIOs buy what they've heard of. Anthropic has to fight for mindshare against a competitor with a massive head start in public awareness.

The safety-capabilities tension is real. Anthropic's entire brand is built on being the "safe" AI company.

But to stay competitive, they must build increasingly powerful models. Every capability improvement creates new risks.

If Anthropic ships something that causes harm, the reputational damage is catastrophic because safety is their core promise. If they move too slowly, they become irrelevant.

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.

Anthropic

Claude is the flagship AI assistant — available via web app, mobile app, and API. Claude excels at long-document analysis, coding, writing, and reasoning.

Claude's context window handles up to 200,000 tokens (roughly 500 pages) — dramatically more than most competitors. The Claude API lets developers build applications powered by Claude.

Claude for Enterprise provides businesses with a private, secure deployment. Constitutional AI is Anthropic's research framework for training AI systems to be helpful, harmless, and honest — the safety methodology that differentiates Claude from competitors.

Stripe

Stripe Payments is the core — accept credit cards, debit cards, Apple Pay, Google Pay, and 135+ payment methods in 195 countries. Stripe Connect lets marketplaces and platforms pay out to sellers (Shopify, Lyft, DoorDash all use it).

Stripe Billing handles subscription and recurring billing. Stripe Atlas lets you incorporate a US company from anywhere in the world — fill out a form, get a Delaware C-corp, bank account, and tax ID in days.

Stripe Radar uses machine learning to block fraud in real time. Stripe Treasury lets platforms offer banking services to their customers.

Stripe Tax automatically calculates and collects sales tax in every jurisdiction.
