Zoom

Zoom uses a freemium model. Free accounts get unlimited one-on-one meetings and 40-minute group meetings.

Paid plans start at $13.33/month per user for Pro (meetings up to 30 hours), $18.33/month for Business, and custom pricing for Enterprise. Zoom also charges for add-ons — Zoom Phone (cloud phone system), Zoom Rooms (conference room hardware), and Zoom Contact Center.

The free tier is the hook. The 40-minute limit on group calls creates just enough friction to push power users to pay.

And once one person in a company pays, the whole team follows because nobody wants to be the one whose meetings keep getting cut off.

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.

Eric Yuan grew up in Tai'an, a mining city in Shandong province, China. In 1997, he was 27 and inspired by the internet boom happening in America.

He applied for a US visa. He was rejected.

He applied again. Rejected again.

Eight times total over two years before he finally got approved in 1997. He moved to Silicon Valley with barely any English and joined WebEx as one of its first engineers.

Yuan spent 14 years at WebEx, eventually becoming VP of Engineering. Cisco acquired WebEx in 2007 for $3.2 billion.

Yuan watched Cisco slowly bloat the product with enterprise features while the core video quality deteriorated. He kept telling Cisco leadership they needed to rebuild the product from scratch.

They kept saying no.

In 2011, Yuan quit and took 40 WebEx engineers with him. He founded Zoom Video Communications with a simple thesis: video meetings should just work.

No downloads. No lag.

No "can you hear me?" No IT department required. He built the product that Cisco refused to build.

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.

Zoom

Zoom grew on one thing: it worked. In a world where every video call started with five minutes of technical issues, Zoom calls just connected.

That reliability was the entire marketing strategy for the first five years.

The freemium model did the rest. Teachers, coaches, therapists, book clubs, and small teams all started on the free tier.

When they hit the 40-minute limit, enough of them converted to paid. And every free meeting was essentially a demo — everyone in the meeting saw how good Zoom was.

Yuan obsessed over simplicity. While competitors like WebEx and GoToMeeting required downloads, plugins, and IT involvement, Zoom worked in the browser with one click.

The learning curve was essentially zero. Your grandmother could figure it out.

That turned out to be extremely important when a pandemic suddenly required your grandmother to figure it out.

Then COVID happened. In March 2020, the world shut down.

Every meeting — work, school, family, doctor, church, happy hour — moved to video. Zoom was already the easiest option.

Daily participants exploded from 10 million to 300 million in four months. The stock went from $70 to $588.

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.

Zoom

The post-pandemic hangover has been severe. Zoom's stock peaked at $588 in October 2020 and crashed to under $70 by 2022 — an 88% drop.

The company went from the most exciting tech stock on the planet to a cautionary tale about pandemic valuations. Revenue growth slowed from 300%+ to single digits as people returned to offices and competitors caught up.

Security and "Zoombombing" were early crises. In early 2020, as millions of new users flooded in, trolls discovered they could join open Zoom meetings and share offensive content.

Schools, churches, and AA meetings were disrupted. It turned out Zoom's encryption wasn't truly end-to-end as advertised.

Yuan had to halt all feature development for 90 days and focus exclusively on security fixes. It was a near-death reputational crisis.

Competition from Microsoft Teams and Google Meet intensified. Both companies bundled video calling for free into products that hundreds of millions of people already used.

Microsoft Teams integrated directly into Office 365. Google Meet was built into Gmail.

Zoom had to compete against free products from two of the richest companies on Earth.

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.

Zoom

Zoom Meetings is the core — video calls that actually work. Zoom Webinars handles large-scale events with up to 50,000 attendees.

Zoom Phone is a full cloud-based phone system replacing traditional office phones. Zoom Rooms turns physical conference rooms into one-click video meeting spaces.

Zoom Contact Center competes with established call center software. Zoom Team Chat is their Slack/Teams competitor.

Zoom Whiteboard is a collaborative digital canvas. Zoom Revenue Accelerator uses AI to analyze sales calls.

And Zoom AI Companion summarizes meetings and drafts messages.

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.
